-In the simple case without the _reasoning_ feature, the Groundedness detection API classifies the ungroundedness of the submitted content as `true` or `false` and provides a confidence score.

-> [!TIP]

-> To test a summarization task instead of a question answering (QnA) task, use the following sample JSON body:

->

-> ```json

-> {

-> "Domain": "Medical",

-> "Task": "Summarization",

-> "Text": "Ms Johnson has been in the hospital after experiencing a stroke.",

-> "GroundingSources": ["Our patient, Ms. Johnson, presented with persistent fatigue, unexplained weight loss, and frequent night sweats. After a series of tests, she was diagnosed with HodgkinΓÇÖs lymphoma, a type of cancer that affects the lymphatic system. The diagnosis was confirmed through a lymph node biopsy revealing the presence of Reed-Sternberg cells, a characteristic of this disease. She was further staged using PET-CT scans. Her treatment plan includes chemotherapy and possibly radiation therapy, depending on her response to treatment. The medical team remains optimistic about her prognosis given the high cure rate of HodgkinΓÇÖs lymphoma."],

-> "Reasoning": false

-| **reasoning** | (Optional) Specifies whether to use the reasoning feature. The default value is `false`. If `true`, you need to bring your own Azure OpenAI resources to provide an explanation. Be careful: using reasoning increases the processing time and incurs extra fees.| Boolean |

-| **confidenceScore** | The confidence value of the _ungrounded_ designation. The score ranges from 0 to 1. | Float |

-| -**`Text`** | The specific text that is ungrounded. | String |

-In order to use your Azure OpenAI resource to enable the reasoning feature, use Managed Identity to allow your Content Safety resource to access the Azure OpenAI resource:

-In your request to the Groundedness detection API, set the `"Reasoning"` body parameter to `true`, and provide the other needed parameters:

-For help with role assignments, see [Assign Azure roles using the Azure portal](../../role-based-access-control/role-assignments-portal.md).

-1. **Document type confidence score**: The document type confidence is an indicator of closely the analyzed document resembleds documents in the training dataset. When the document type confidence is low, this is indicative of template or structural variations in the analyzed document. To improve the document type confidence, label a document with that specific variation and add it to your training dataset. Once the model is re-trained, it should be better equipped to handl that class of variations.

-2. **Field level confidence**: Each labled field extracted has an associated confidence score. This score reflects the model's confidence on the position of the value extracted. While evaluating the confidence you should also look at the underlying extraction confidence to generate a comprehensive confidence for the extracted result. Evaluate the OCR results for text extraction or selection marks depending on the field type to generate a composite confidence score for the field.

-3. **Word confidence score** Each word extracted within the document has an associated confidence score. The score represents the confidence of the transcription. The pages array contains an array of words, each word has an associated span and confidence. Spans from the custom field extracted values will match the spans of the extracted words.

-4. **Selection mark confidence score**: The pages array also contains an array of selection marks, each selection mark has a confidence score representing the confidence of the seletion mark and selection state detection. When a labeled field is a selection mark, the custom field selection confidence combined with the selection mark confidence is an accurate representation of the overall confidence that the field was extracted correctly.

-## To Avoid Fabrication or Ungrounded Content

-You need to connect to a data source to upload your data. When you want to use your data to chat with an Azure OpenAI model, your data is chunked in a search index so that relevant data can be found based on user queries. For some data sources such as uploading files from your local machine (preview) or data contained in a blob storage account (preview), Azure AI Search is used.

-When you choose the following data sources, your data is ingested into an Azure AI Search index.

-# [Azure Cosmos DB for MongoDB vCore](#tab/mongo-db)

-* [Azure Cosmos DB for MongoDB vCore](/azure/cosmos-db/mongodb/vcore/introduction) account

-* Only Azure Cosmos DB for MongoDB vCore is supported.

-* The search type is limited to [Azure Cosmos DB for MongoDB vCore vector search](/azure/cosmos-db/mongodb/vcore/vector-search) with an Azure OpenAI embedding model.

-Use the script provided on [GitHub](https://github.com/microsoft/sample-app-aoai-chatGPT/blob/feature/2023-9/scripts/cosmos_mongo_vcore_data_preparation.py) to prepare your data.

-To add Azure Cosmos DB for MongoDB vCore as a data source, you will need an existing Azure Cosmos DB for MongoDB vCore index containing your data, and a deployed Azure OpenAI Ada embeddings model that will be used for vector search.

-1. In the [Azure OpenAI portal](https://oai.azure.com/portal) chat playground, select **Add your data**. In the panel that appears, select **Azure Cosmos DB for MongoDB vCore** as the data source.

-When you add your Azure Cosmos DB for MongoDB vCore data source, you can specify data fields to properly map your data for retrieval.

-### Failed ingestion jobs

-To troubleshoot a failed job, always look out for errors or warnings specified either in the API response or Azure OpenAI studio. Here are some of the common errors and warnings:

-description: Learn how to create helpful AI Assistants with tools like Code Interpreter

-Azure OpenAI Assistants (Preview) allows you to create AI assistants tailored to your needs through custom instructions and augmented by advanced tools like code interpreter, and custom functions. In this article we'll provide an in-depth walkthrough of getting started with the Assistants API.

-Now let's create a thread

-A thread is essentially the record of the conversation session between the assistant and the user. It's similar to the messages array/list in a typical chat completions API call. One of the key differences, is unlike a chat completions messages array, you don't need to track tokens with each call to make sure that you're remaining below the context length of the model. Threads abstract away this management detail and will compress the thread history as needed in order to allow the conversation to continue. The ability for threads to accomplish this with larger conversations is enhanced when using the latest models, which have larger context lengths as well as support for the latest features.

-Next create the first user question to add to the thread

-description: Learn about the options for how to use the GPT-35-Turbo and GPT-4 models

-zone_pivot_groups: openai-chat

-# Learn how to work with the GPT-35-Turbo and GPT-4 models

-The GPT-35-Turbo and GPT-4 models are language models that are optimized for conversational interfaces. The models behave differently than the older GPT-3 models. Previous models were text-in and text-out, meaning they accepted a prompt string and returned a completion to append to the prompt. However, the GPT-35-Turbo and GPT-4 models are conversation-in and message-out. The models expect input formatted in a specific chat-like transcript format, and return a completion that represents a model-written message in the chat. While this format was designed specifically for multi-turn conversations, you'll find it can also work well for non-chat scenarios too.

-In Azure OpenAI there are two different options for interacting with these type of models:

-The Chat Completion API is a new dedicated API for interacting with the GPT-35-Turbo and GPT-4 models. This API is the preferred method for accessing these models. **It is also the only way to access the new GPT-4 models**.

-ChatML uses the same [completion API](../reference.md#completions) that you use for other models like text-davinci-002, it requires a unique token based prompt format known as Chat Markup Language (ChatML). This provides lower level access than the dedicated Chat Completion API, but also requires additional input validation, only supports gpt-35-turbo models, and **the underlying format is more likely to change over time**.

-This article walks you through getting started with the GPT-35-Turbo and GPT-4 models. It's important to use the techniques described here to get the best results. If you try to interact with the models the same way you did with the older model series, the models will often be verbose and provide less useful responses.

-Assistants use the [same API for file upload as fine-tuning](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP). When uploading a file you have to specify an appropriate value for the [purpose parameter](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP#purpose).

-In the beginning, there was nothingness, a vast expanse of empty space, a blank canvas waiting to be painted with the wonders of existence. Then, approximately 13.8 billion years ago, something extraordinary happened, an event that would mark the birth of the universe ΓÇô the Big Bang.

-The Big Bang was not an explosion in the conventional sense but rather an expansion, an incredibly rapid stretching of space that took place everywhere in the universe at once. In just a fraction of a second, the universe grew from smaller than a single atom to an incomprehensibly large expanse.

-In these first moments, the universe was unimaginably hot and dense, filled with a seething soup of subatomic particles and radiant energy. As the universe expanded, it began to cool, allowing the first particles to form. Protons and neutrons came together to create the first simple atomic nuclei in a process known as nucleosynthesis.

-For hundreds of thousands of years, the universe continued to cool and expand

-Once upon a time, in the vast expanse of nothingness, there was a moment that would come to define everything. This moment, a tiny fraction of a second that would be forever known as the Big Bang, marked the birth of the universe as we know it.

-Before this moment, there was no space, no time, just an infinitesimally small point of pure energy, a singularity where all the laws of physics as we understand them did not apply. Then, suddenly, this singular point began to expand at an incredible rate. In a cosmic symphony of creation, matter, energy, space, and time all burst forth into existence.

-The universe was a hot, dense soup of particles, a place of unimaginable heat and pressure. It was in this crucible of creation that the simplest elements were formed. Hydrogen and helium, the building blocks of the cosmos, came into being.

-As the universe continued to expand and cool, these primordial elements began to co

-Once upon a time, in the vast expanse of nothingness, there was a singularity, an infinitely small and infinitely dense point where all the mass and energy of what would become the universe were concentrated. This singularity was like a tightly wound cosmic spring holding within it the potential of everything that would ever exist.

-Then, approximately 13.8 billion years ago, something extraordinary happened. This singularity began to expand in an event we now call the Big Bang. In just a fraction of a second, the universe grew exponentially during a period known as cosmic inflation. It was like a symphony's first resounding chord, setting the stage for a cosmic performance that would unfold over billions of years.

-As the universe expanded and cooled, the fundamental forces of nature that we know today ΓÇô gravity, electromagnetism, and the strong and weak nuclear forces ΓÇô began to take shape. Particles of matter were created and began to clump together under the force of gravity, forming the first atoms

-## Keyword argument for model

-OpenAI uses the `model` keyword argument to specify what model to use. Azure OpenAI has the concept of unique model [deployments](create-resource.md?pivots=web-portal#deploy-a-model). When using Azure OpenAI `model` should refer to the underlying deployment name you chose when you deployed the model.

-> [!IMPORTANT]

-> When you access the model via the API in Azure OpenAI you will need to refer to the deployment name rather than the underlying model name in API calls. This is one of the [key differences](../how-to/switching-endpoints.md) between OpenAI and Azure OpenAI. OpenAI only requires the model name, Azure OpenAI always requires deployment name, even when using the model parameter. In our docs we often have examples where deployment names are represented as identical to model names to help indicate which model works with a particular API endpoint. Ultimately your deployment names can follow whatever naming convention is best for your use case.

-## Resources configuration

-> To allow access to your Azure AI Search resource from Azure OpenAI resource, you need to submit an [application form](https://aka.ms/applyacsvpnaoaioyd). The application will be reviewed in 10 business days and you will be contacted via email about the results. If you are eligible, we will provision the private endpoint in Microsoft managed virtual network, and send a private endpoint connection request to your search service, and you will need to approve the request.

-See the [ingestion API reference article](/azure/ai-services/openai/reference#start-an-ingestion-job) for details on the request and response objects used by the ingestion API.

-The Whisper models, currently in preview, can be used to transcribe and translate speech to text.

-| Max Files per resource (fine-tuning) | 30 |

- "n": 3,

-| ```file```| file | Yes | N/A | The audio file object (not file name) to transcribe, in one of these formats: `flac`, `mp3`, `mp4`, `mpeg`, `mpga`, `m4a`, `ogg`, `wav`, or `webm`.<br/><br/>The file size limit for the Azure OpenAI Whisper model is 25 MB. If you need to transcribe a file larger than 25 MB, break it into chunks. Alternatively you can use the Azure AI Speech [batch transcription](../speech-service/batch-transcription-create.md#use-a-whisper-model) API.<br/><br/>You can get sample audio files from the [Azure AI Speech SDK repository at GitHub](https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/sampledata/audiofiles). |

-Azure OpenAI is deployed as a part of the Azure AI services. All Azure AI services rely on the same set of management APIs for creation, update, and delete operations. The management APIs are also used for deploying models within an OpenAI resource.

-If you want to clean up and remove an OpenAI resource, you can delete the resource. Before deleting the resource, you must first delete any deployed models.

-If you created an OpenAI resource solely for completing this tutorial and want to clean up and remove an OpenAI resource, you'll need to delete your deployed models, and then delete the resource or associated resource group if it's dedicated to your test resource. Deleting the resource group also deletes any other resources associated with it.

-# Azure AI SDK reference

-> The maximum JSON payload size that will be accepted is 2 megabytes. Each Speech resource can have up to 300 batch synthesis jobs that are running concurrently.

-To create a transcription, use the [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) operation of the [Speech to text REST API](rest-speech-to-text.md#transcriptions). Construct the request body according to the following instructions:

-Make an HTTP POST request that uses the URI as shown in the following [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) example.

-The top-level `self` property in the response body is the transcription's URI. Use this URI to [get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) details such as the URI of the transcriptions and transcription report files. You also use this URI to [update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Update) or [delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Delete) a transcription.

-You can query the status of your transcriptions with the [Transcriptions_Get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) operation.

-Call [Transcriptions_Delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Delete)

-Here are some property options that you can use to configure a transcription when you call the [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) operation.

-|`diarization`|Indicates that the Speech service should attempt diarization analysis on the input, which is expected to be a mono channel that contains multiple voices. The feature isn't available with stereo recordings.<br/><br/>Diarization is the process of separating speakers in audio data. The batch pipeline can recognize and separate multiple speakers on mono channel recordings.<br/><br/>Specify the minimum and maximum number of people who might be speaking. You must also set the `diarizationEnabled` property to `true`. The [transcription file](batch-transcription-get.md#transcription-result-file) contains a `speaker` entry for each transcribed phrase.<br/><br/>You need to use this property when you expect three or more speakers. For two speakers, setting `diarizationEnabled` property to `true` is enough. For an example of the property usage, see [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create).<br/><br/>The maximum number of speakers for diarization must be less than 36 and more or equal to the `minSpeakers` property. For an example, see [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create).<br/><br/>When this property is selected, source audio length can't exceed 240 minutes per file.<br/><br/>**Note**: This property is only available with Speech to text REST API version 3.1 and later. If you set this property with any previous version, such as version 3.0, it's ignored and only two speakers are identified.|

-|`timeToLive`|A duration after the transcription job is created, when the transcription results will be automatically deleted. The value is an ISO 8601 encoded duration. For example, specify `PT12H` for 12 hours. As an alternative, you can call [Transcriptions_Delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Delete) regularly after you retrieve the transcription results.|

-Whisper models by batch transcription are supported in the East US, Southeast Asia, and West Europe regions.

-You can make a [Models_ListBaseModels](https://westus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-2-preview2/operations/Models_ListBaseModels) request to get available base models for all locales.

-To get the status of the transcription job, call the [Transcriptions_Get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) operation of the [Speech to text REST API](rest-speech-to-text.md).

-The [Transcriptions_ListFiles](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) operation returns a list of result files for a transcription. A [transcription report](#transcription-report-file) file is provided for each submitted batch transcription job. In addition, one [transcription](#transcription-result-file) file (the end result) is provided for each successfully transcribed audio file.

-Batch transcription is used to transcribe a large amount of audio data in storage. Both the [Speech to text REST API](rest-speech-to-text.md#transcriptions) and [Speech CLI](spx-basics.md) support batch transcription.

-[Speech to text REST API](rest-speech-to-text.md) fully supports BYOS-enabled Speech resources. However, because the data is now stored within the BYOS-enabled Storage account, requests like [Get Transcription Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) interact with the BYOS-associated Storage account Blob storage, instead of Speech service internal resources. It allows using the same REST API based code for both "regular" and BYOS-enabled Speech resources.

-For maximum security use the `sasValidityInSeconds` parameter with the value set to `0` in the requests, that return data file URLs, like [Get Transcription Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) request. Here's an example request URL:

-> If `sasValidityInSeconds` parameter is omitted in [Get Transcription Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) request or similar ones, then a [User delegation SAS](../../storage/common/storage-sas-overview.md) with the validity of 30 days will be generated for each data file URL returned. This SAS is signed by the system assigned managed identity of your BYOS-enabled Speech resource. Because of it, the SAS allows access to the data, even if storage account key access is disabled. See details [here](../../storage/common/shared-key-authorization-prevent.md#understand-how-disallowing-shared-key-affects-sas-tokens).

-> Logging data is kept for 30 days. After this period the logs are automatically deleted. This is valid for BYOS-enabled Speech resources as well. If you want to keep the logs longer, copy the correspondent files and folders from `customspeech-audiologs` Blob container directly or use REST API.

-[Speech to text REST API](rest-speech-to-text.md) fully supports BYOS-enabled Speech resources. However, because the data is now stored within the BYOS-enabled Storage account, requests like [Get Base Model Logs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListBaseModelLogs) interact with the BYOS-associated Storage account Blob storage, instead of Speech service internal resources. It allows using the same REST API based code for both "regular" and BYOS-enabled Speech resources.

-For maximum security use the `sasValidityInSeconds` parameter with the value set to `0` in the requests, that return data file URLs, like [Get Base Model Logs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListBaseModelLogs) request. Here's an example request URL:

-> If `sasValidityInSeconds` parameter is omitted in [Get Base Model Logs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListBaseModelLogs) request or similar ones, then a [User delegation SAS](../../storage/common/storage-sas-overview.md) with the validity of 30 days will be generated for each data file URL returned. This SAS is signed by the system assigned managed identity of your BYOS-enabled Speech resource. Because of it, the SAS allows access to the data, even if storage account key access is disabled. See details [here](../../storage/common/shared-key-authorization-prevent.md#understand-how-disallowing-shared-key-affects-sas-tokens).

-[Speech to text REST API](rest-speech-to-text.md) fully supports BYOS-enabled Speech resources. However, because the data is now stored within the BYOS-enabled Storage account, requests like [Get Dataset Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_ListFiles) interact with the BYOS-associated Storage account Blob storage, instead of Speech service internal resources. It allows using the same REST API based code for both "regular" and BYOS-enabled Speech resources.

-For maximum security use the `sasValidityInSeconds` parameter with the value set to `0` in the requests, that return data file URLs, like [Get Dataset Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_ListFiles) request. Here's an example request URL:

-> If `sasValidityInSeconds` parameter is omitted in [Get Dataset Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_ListFiles) request or similar ones, then a [User delegation SAS](../../storage/common/storage-sas-overview.md) with the validity of 30 days will be generated for each data file URL returned. This SAS is signed by the system assigned managed identity of your BYOS-enabled Speech resource. Because of it, the SAS allows access to the data, even if storage account key access is disabled. See details [here](../../storage/common/shared-key-authorization-prevent.md#understand-how-disallowing-shared-key-affects-sas-tokens).

-To create a project, use the [Projects_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Create) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-Make an HTTP POST request using the URI as shown in the following [Projects_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Create) example. Replace `YourSubscriptionKey` with your Speech resource key, replace `YourServiceRegion` with your Speech resource region, and set the request body properties as previously described.

-The top-level `self` property in the response body is the project's URI. Use this URI to [get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Get) details about the project's evaluations, datasets, models, endpoints, and transcriptions. You also use this URI to [update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Update) or [delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Delete) a project.

-To create an endpoint and deploy a model, use the [Endpoints_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Create) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-Make an HTTP POST request using the URI as shown in the following [Endpoints_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Create) example. Replace `YourSubscriptionKey` with your Speech resource key, replace `YourServiceRegion` with your Speech resource region, and set the request body properties as previously described.

-The top-level `self` property in the response body is the endpoint's URI. Use this URI to [get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Get) details about the endpoint's project, model, and logs. You also use this URI to [update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Update) or [delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Delete) the endpoint.

-To redeploy the custom endpoint with a new model, use the [Endpoints_Update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Update) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-To get logs for an endpoint, start by using the [Endpoints_Get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Get) operation of the [Speech to text REST API](rest-speech-to-text.md).

-To create a test, use the [Evaluations_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Evaluations_Create) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-If you train a custom model with audio data, choose a Speech resource region with dedicated hardware for training audio data. For more information, see footnotes in the [regions](regions.md#speech-service) table. In regions with dedicated hardware for custom speech training, the Speech service uses up to 20 hours of your audio training data, and can process about 10 hours of data per day. In other regions, the Speech service uses up to 8 hours of your audio data, and can process about 1 hour of data per day. After the model is trained, you can copy the model to another region as needed with the [Models_CopyTo](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_CopyTo) REST API.

GUID value `537216f8-0620-4a10-ae2d-00bdb423b36f` found in the first `self` element is the Transcription ID.

-> Use the same technique to determine different IDs required for debugging issues related to [custom speech](custom-speech-overview.md), like uploading a dataset using [Datasets_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_Create) request.

-> You can also see all existing transcriptions and their Transcription IDs for a given Speech resource by using [Transcriptions_Get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) request.

-> We are retiring the standard voices from September 1, 2021 through August 31, 2024. If you used a standard voice with your Speech resource that was created prior to September 1, 2021 then you can continue to do so until August 31, 2024. To use neural voices, choose voice names that include 'Neural' in their name, for example: en-US-JennyMultilingualNeural. All other Speech resources can only use prebuilt neural voices. You can choose from the supported [neural voice names](language-support.md?tabs=tts). After August 31, 2024 the standard voices won't be supported with any Speech resource.

-To identify languages with [Batch transcription REST API](batch-transcription.md), use `languageIdentification` property in the body of your [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) request.

-The table in this section summarizes the 27 locales supported for pronunciation assessment, and each language is available on all [Speech to text regions](regions.md#speech-service). Latest update extends support from English to 26 more languages and quality enhancements to existing features, including accuracy, fluency and miscue assessment. You should specify the language that you're learning or practicing improving pronunciation. The default language is set as `en-US`. If you know your target learning language, [set the locale](how-to-pronunciation-assessment.md#get-pronunciation-assessment-results) accordingly. For example, if you're learning British English, you should specify the language as `en-GB`. If you're teaching a broader language, such as Spanish, and are uncertain about which locale to select, you can run various accent models (`es-ES`, `es-MX`) to determine the one that achieves the highest score to suit your specific scenario.

-To turn off logging for a custom endpoint, use the [Endpoints_Update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Update) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-Here's a sample output of [Endpoints_ListLogs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListLogs). For simplicity, only one log set is shown:

-description: This document helps developers migrate code from v2 to v3 of the Speech to text REST API.speech-to-text REST API.

-# Migrate code from v2.0 to v3.0 of the REST API

-> [!IMPORTANT]

-> The Speech to text REST API v2.0 is retired as of February 29, 2024. Please migrate your applications to the Speech to text REST API v3.2. Complete the steps in this article and then see the Speech to text REST API [v3.0 to v3.1](migrate-v3-0-to-v3-1.md) and [v3.1 to v3.2](migrate-v3-1-to-v3-2.md) migration guides for additional requirements.

-## Forward compatibility

-All entities from v2.0 can also be found in the v3.0 API under the same identity. Where the schema of a result has changed (such as transcriptions), the result of a GET in the v3 version of the API uses the v3 schema. The result of a GET in the v2 version of the API uses the same v2 schema. Newly created entities on v3 aren't available in responses from v2 APIs.

-## Migration steps

-This is a summary list of items you need to be aware of when you're preparing for migration. Details are found in the individual links. Depending on your current use of the API not all steps listed here might apply. Only a few changes require nontrivial changes in the calling code. Most changes just require a change to item names.

-General changes:

-1. [Change the host name](#host-name-changes)

-1. [Rename the property ID to self in your client code](#identity-of-an-entity)

-1. [Change code to iterate over collections of entities](#working-with-collections-of-entities)

-1. [Rename the property name to displayName in your client code](#name-of-an-entity)

-1. [Adjust the retrieval of the metadata of referenced entities](#accessing-referenced-entities)

-1. If you use Batch transcription:

- * [Adjust code for creating batch transcriptions](#creating-transcriptions)

- * [Adapt code to the new transcription results schema](#format-of-v3-transcription-results)

- * [Adjust code for how results are retrieved](#getting-the-content-of-entities-and-the-results)

-1. If you use Custom model training/testing APIs:

- * [Apply modifications to custom model training](#customizing-models)

- * [Change how base and custom models are retrieved](#retrieving-base-and-custom-models)

- * [Rename the path segment accuracy tests to evaluations in your client code](#accuracy-tests)

-1. If you use endpoints APIs:

- * [Change how endpoint logs are retrieved](#retrieving-endpoint-logs)

-1. Other minor changes:

- * [Pass all custom properties as customProperties instead of properties in your POST requests](#using-custom-properties)

- * [Read the location from response header Location instead of Operation-Location](#response-headers)

-## Breaking changes

-### Host name changes

-Endpoint host names changed from `{region}.cris.ai` to `{region}.api.cognitive.microsoft.com`. Paths to the new endpoints no longer contain `api/` because it's part of the hostname. The [Speech to text REST API v3.0](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0) reference documentation lists valid regions and paths.

->[!IMPORTANT]

->Change the hostname from `{region}.cris.ai` to `{region}.api.cognitive.microsoft.com` where region is the region of your speech subscription. Also remove `api/`from any path in your client code.

-### Identity of an entity

-The property `id` is now `self`. In v2, an API user had to know how our paths on the API are being created. This was non-extensible and required unnecessary work from the user. The property `id` (uuid) is replaced by `self` (string), which is location of the entity (URL). The value is still unique between all your entities. If `id` is stored as a string in your code, a rename is enough to support the new schema. You can now use the `self` content as the URL for the `GET`, `PATCH`, and `DELETE` REST calls for your entity.

-If the entity has more functionality available through other paths, they're listed under `links`. The following example for transcription shows a separate method to `GET` the content of the transcription:

->[!IMPORTANT]

->Rename the property `id` to `self` in your client code. Change the type from `uuid` to `string` if needed.

-**v2 transcription:**

-```json

-{

- "id": "9891c965-bb32-4880-b14b-6d44efb158f3",

- "createdDateTime": "2019-01-07T11:34:12Z",

- "lastActionDateTime": "2019-01-07T11:36:07Z",

- "status": "Succeeded",

- "locale": "en-US",

- "name": "Transcription using locale en-US"

-}

-```

-**v3 transcription:**

-```json

-{

- "self": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/transcriptions/9891c965-bb32-4880-b14b-6d44efb158f3",

- "createdDateTime": "2019-01-07T11:34:12Z",

- "lastActionDateTime": "2019-01-07T11:36:07Z",

- "status": "Succeeded",

- "locale": "en-US",

- "displayName": "Transcription using locale en-US",

- "links": {

- "files": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/transcriptions/9891c965-bb32-4880-b14b-6d44efb158f3/files"

- }

-}

-```

-Depending on your code's implementation, it might not be enough to rename the property. We recommend using the returned `self` and `links` values as the target urls of your REST calls, rather than generating paths in your client. By using the returned URLs, you can be sure that future changes in paths won't break your client code.

-### Working with collections of entities

-Previously the v2 API returned all available entities in a result. To allow a more fine grained control over the expected response size in v3, all collection results are paginated. You have control over the count of returned entities and the starting offset of the page. This behavior makes it easy to predict the runtime of the response processor.

-The basic shape of the response is the same for all collections:

-```json

-{

- "values": [

- {

- }

- ],

- "@nextLink": "https://{region}.api.cognitive.microsoft.com/speechtotext/v3.0/{collection}?skip=100&top=100"

-}

-```

-The `values` property contains a subset of the available collection entities. The count and offset can be controlled using the `skip` and `top` query parameters. When `@nextLink` isn't `null`, there's more data available and the next batch of data can be retrieved by doing a GET on `$.@nextLink`.

-This change requires calling the `GET` for the collection in a loop until all elements are returned.

->[!IMPORTANT]

->When the response of a GET to `speechtotext/v3.1/{collection}` contains a value in `$.@nextLink`, continue issuing `GETs` on `$.@nextLink` until `$.@nextLink` is not set to retrieve all elements of that collection.

-### Creating transcriptions

-A detailed description on how to create batches of transcriptions can be found in [Batch transcription How-to](./batch-transcription.md).

-The v3 transcription API lets you set specific transcription options explicitly. All (optional) configuration properties can now be set in the `properties` property.

-Version v3 also supports multiple input files, so it requires a list of URLs rather than a single URL as v2 did. The v2 property name `recordingsUrl` is now `contentUrls` in v3. The functionality of analyzing sentiment in transcriptions is removed in v3. See [Text Analysis](https://azure.microsoft.com/services/cognitive-services/text-analytics/) for sentiment analysis options.

-The new property `timeToLive` under `properties` can help prune the existing completed entities. The `timeToLive` specifies a duration after which a completed entity is deleted automatically. Set it to a high value (for example `PT12H`) when the entities are continuously tracked, consumed, and deleted and therefore usually processed long before 12 hours have passed.

-**v2 transcription POST request body:**

-```json

-{

- "locale": "en-US",

- "name": "Transcription using locale en-US",

- "recordingsUrl": "https://contoso.com/mystoragelocation",

- "properties": {

- "AddDiarization": "False",

- "AddWordLevelTimestamps": "False",

- "PunctuationMode": "DictatedAndAutomatic",

- "ProfanityFilterMode": "Masked"

- }

-}

-```

-**v3 transcription POST request body:**

-```json

-{

- "locale": "en-US",

- "displayName": "Transcription using locale en-US",

- "contentUrls": [

- "https://contoso.com/mystoragelocation",

- "https://contoso.com/myotherstoragelocation"

- ],

- "properties": {

- "diarizationEnabled": false,

- "wordLevelTimestampsEnabled": false,

- "punctuationMode": "DictatedAndAutomatic",

- "profanityFilterMode": "Masked"

- }

-}

-```

->[!IMPORTANT]

->Rename the property `recordingsUrl` to `contentUrls` and pass an array of urls instead of a single url. Pass settings for `diarizationEnabled` or `wordLevelTimestampsEnabled` as `bool` instead of `string`.

-### Format of v3 transcription results

-The schema of transcription results has changed slightly to align with transcriptions created by real-time endpoints. Find an in-depth description of the new format in the [Batch transcription How-to](./batch-transcription.md). The schema of the result is published in our [GitHub sample repository](https://aka.ms/csspeech/samples) under `samples/batch/transcriptionresult_v3.schema.json`.

-Property names are now camel-cased and the values for `channel` and `speaker` now use integer types. Formats for durations now use the structure described in ISO 8601, which matches duration formatting used in other Azure APIs.

-Sample of a v3 transcription result. The differences are described in the comments.

-```json

- }

- ]

- }

- ]

- }

- ]

-}

-```

->[!IMPORTANT]

->Deserialize the transcription result into the new type as shown previously. Instead of a single file per audio channel, distinguish channels by checking the property value of `channel` for each element in `recognizedPhrases`. There is now a single result file for each input file.

-### Getting the content of entities and the results

-In v2, the links to the input or result files are inline with the rest of the entity metadata. As an improvement in v3, there's a clear separation between entity metadata (which is returned by a GET on `$.self`) and the details and credentials to access the result files. This separation helps protect customer data and allows fine control over the duration of validity of the credentials.

-In v3, `links` include a sub-property called `files` in case the entity exposes data (datasets, transcriptions, endpoints, or evaluations). A GET on `$.links.files` returns a list of files and a SAS URL

-to access the content of each file. To control the validity duration of the SAS URLs, the query parameter `sasValidityInSeconds` can be used to specify the lifetime.

-Before v3, there was a distinction between an _acoustic model_ and a _language model_ when a model was being trained. This distinction resulted in the need to specify multiple models when creating endpoints or transcriptions. To simplify this process for a caller, we removed the differences and made everything depend on the content of the datasets that are being used for model training. With this change, the model creation now supports mixed datasets (language data and acoustic data). Endpoints and transcriptions now require only one model.

-With this change, the need for a `kind` in the `POST` operation is removed and the `datasets[]` array can now contain multiple datasets of the same or mixed kinds.

-To improve the results of a trained model, the acoustic data is automatically used internally during language training. In general, models created through the v3 API deliver more accurate results than models created with the v2 API.

->[!IMPORTANT]

->To customize both the acoustic and language model part, pass all of the required language and acoustic datasets in `datasets[]` of the POST to `/speechtotext/v3.0/models`. This will create a single model with both parts customized.

-### Retrieving base and custom models

-To simplify getting the available models, v3 has separated the collections of "base models" from the customer owned "customized models". The two routes are now

-`GET /speechtotext/v3.0/models/base` and `GET /speechtotext/v3.0/models/`.

-In v2, all models were returned together in a single response.

->[!IMPORTANT]

->To get a list of provided base models for customization, use `GET` on `/speechtotext/v3.0/models/base`. You can find your own customized models with a `GET` on `/speechtotext/v3.0/models`.

-### Name of an entity

-The `name` property is now `displayName`. This is consistent with other Azure APIs to not indicate identity properties. The value of this property must not be unique and can be changed after entity creation with a `PATCH` operation.

-**v2 transcription:**

-```json

-{

- "name": "Transcription using locale en-US"

-}

-```

-**v3 transcription:**

-```json

-{

- "displayName": "Transcription using locale en-US"

-}

-```

->[!IMPORTANT]

->Rename the property `name` to `displayName` in your client code.

-### Accessing referenced entities

-In v2, referenced entities were always inlined, for example the used models of an endpoint. The nesting of entities resulted in large responses and consumers rarely consumed the nested content. To shrink the response size and improve performance, the referenced entities are no longer inlined in the response. Instead, a reference to the other entity appears, and can directly be used for a subsequent `GET` (it's a URL as well), following the same pattern as the `self` link.

-**v2 transcription:**

-```json

-{

- "id": "9891c965-bb32-4880-b14b-6d44efb158f3",

- "models": [

-}

-```

-**v3 transcription:**

-```json

-{

- }

-}

-```

-If you need to consume the details of a referenced model as shown in the above example, just issue a GET on `$.model.self`.

->[!IMPORTANT]

->To retrieve the metadata of referenced entities, issue a GET on `$.{referencedEntity}.self`, for example to retrieve the model of a transcription do a `GET` on `$.model.self`.

-### Retrieving endpoint logs

-Version v2 of the service supported logging endpoint results. To retrieve the results of an endpoint with v2, you would create a "data export", which represented a snapshot of the results defined by a time range. The process of exporting batches of data was inflexible. The v3 API gives access to each individual file and allows iteration through them.

-**A successfully running v3 endpoint:**

-```json

-{

- "self": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/endpoints/afa0669c-a01e-4693-ae3a-93baf40f26d6",

- "links": {

- "logs": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/endpoints/afa0669c-a01e-4693-ae3a-93baf40f26d6/files/logs"

- }

-}

-```

-**Response of GET `$.links.logs`:**

-}

-```

-Pagination for endpoint logs works similar to all other collections, except that no offset can be specified. Due to the large amount of available data, pagination is determined by the server.

-In v3, each endpoint log can be deleted individually by issuing a `DELETE` operation on the `self` of a file, or by using `DELETE` on `$.links.logs`. To specify an end date, the query parameter `endDate` can be added to the request.

-> [!IMPORTANT]

-> Instead of creating log exports on `/api/speechtotext/v2.0/endpoints/{id}/data` use `/v3.0/endpoints/{id}/files/logs/` to access log files individually.

-### Using custom properties

-To separate custom properties from the optional configuration properties, all explicitly named properties are now located in the `properties` property and all properties defined by the callers are now located in the `customProperties` property.

-**v2 transcription entity:**

-```json

-{

- "properties": {

- "customerDefinedKey": "value",

- "diarizationEnabled": "False",

- "wordLevelTimestampsEnabled": "False"

- }

-}

-```

-**v3 transcription entity:**

-```json

-{

- "properties": {

- "diarizationEnabled": false,

- "wordLevelTimestampsEnabled": false

- },

- "customProperties": {

- "customerDefinedKey": "value"

- }

-}

-```

-This change also lets you use correct types on all explicitly named properties under `properties` (for example boolean instead of string).

->[!IMPORTANT]

->Pass all custom properties as `customProperties` instead of `properties` in your `POST` requests.

-### Response headers

-v3 no longer returns the `Operation-Location` header in addition to the `Location` header on `POST` requests. The value of both headers in v2 was the same. Now only `Location` is returned.

-Because the new API version is now managed by Azure API management (APIM), the throttling related headers `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` aren't contained in the response headers.

->[!IMPORTANT]

->Read the location from response header `Location` instead of `Operation-Location`. In case of a 429 response code, read the `Retry-After` header value instead of `X-RateLimit-Limit`, `X-RateLimit-Remaining`, or `X-RateLimit-Reset`.

-### Accuracy tests

-Accuracy tests have been renamed to evaluations because the new name describes better what they represent. The new paths are: `https://{region}.api.cognitive.microsoft.com/speechtotext/v3.0/evaluations`.

->[!IMPORTANT]

->Rename the path segment `accuracytests` to `evaluations` in your client code.

-* [Speech to text REST API v3.0 reference](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0)

-In the [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) operation the following three properties are added:

-The `filter` property is added to the [Transcriptions_List](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_List), [Transcriptions_ListFiles](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles), and [Projects_ListTranscriptions](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_ListTranscriptions) operations. The `filter` expression can be used to select a subset of the available resources. You can filter by `displayName`, `description`, `createdDateTime`, `lastActionDateTime`, `status`, and `locale`. For example: `filter=createdDateTime gt 2022-02-01T11:00:00Z`

-To support model adaptation with [structured text in markdown](how-to-custom-speech-test-and-train.md#structured-text-data-for-training) data, the [Datasets_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_Create) operation now supports the **LanguageMarkdown** data kind. For more information, see [upload datasets](how-to-custom-speech-upload-data.md#upload-datasets).

-The [Models_ListBaseModels](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_ListBaseModels) and [Models_GetBaseModel](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_GetBaseModel) operations return information on the type of adaptation supported by each base model.

-The [Models_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_Create) operation has a new `customModelWeightPercent` property where you can specify the weight used when the Custom Language Model (trained from plain or structured text data) is combined with the Base Language Model. Valid values are integers between 1 and 100. The default value is currently 30.

-Added the [Models_ListFiles](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_ListFiles) operation to get the files of the model identified by the given ID.

-Added the [Models_GetFile](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_GetFile) operation to get one specific file (identified with fileId) from a model (identified with ID). This lets you retrieve a **ModelReport** file that provides information on the data processed during training.

-The name of each `operationId` in version 3.1 is prefixed with the object name. For example, the `operationId` for "Create Model" changed from [CreateModel](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0/operations/CreateModel) in version 3.0 to [Models_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_Create) in version 3.1.

-> We are retiring the standard voices from September 1, 2021 through August 31, 2024. If you used a standard voice with your Speech resource that was created prior to September 1, 2021 then you can continue to do so until August 31, 2024. All other Speech resources can only use prebuilt neural voices. You can choose from the supported [neural voice names](language-support.md?tabs=tts). After August 31, 2024 the standard voices won't be supported with any Speech resource.

-| **Speech output audio format** | opus, mp3, aac, flac | opus, mp3, pcm, truesilk | opus, mp3, pcm, truesilk |

-The following table outlines the Speech Synthesis Markup Language (SSML) elements supported by OpenAI text to speech voices in Azure AI speech. Only a subset of SSML tags are supported for OpenAI voices. See [SSML document structure and events](speech-synthesis-markup-structure.md) for more information.

-The demo in Speech Studio is made available to approved customers. You can apply for access [here](https://aka.ms/customneural).

-1. Select **Request demo access**.

-1. After your access is approved, you can record your own voice and try the voice output samples in different languages. The demo includes a subset of the languages supported by personal voice.

-This article describes how to use [Power Automate](/power-automate/getting-started) and the [Azure AI services for Batch Speech to text connector](/connectors/cognitiveservicesspe/) to transcribe audio files from an Azure Storage container. The connector uses the [Batch Transcription REST API](batch-transcription.md), but you don't need to write any code to use it. If the connector doesn't meet your requirements, you can still use the [REST API](rest-speech-to-text.md#transcriptions) directly.

-2. Run the [Models_CopyTo](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_CopyTo) operation to replicate the custom model to all prepared regions (Secondary).

-The [Swagger specification](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1) has options that allow you to quickly test for various paths. However, sometimes it's desirable to generate code for all paths, creating a single library of calls that you can base future solutions on. Let's take a look at the process to generate a Python library.

-1. In a browser, go to the Swagger specification for your [region](regions.md#speech-service):

- `https://<your-region>.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1`

-1. On that page, select **API definition**, and select **Swagger**. Copy the URL of the page that appears.

-1. In a new browser, go to [https://editor.swagger.io](https://editor.swagger.io)

-1. Select **File**, select **Import URL**, paste the URL, and select **OK**.

-description: The Translator container runtime environment is configured using the `docker run` command arguments. There are both required and optional settings.

-#

-recommendations: false

-# Configure Translator Docker containers

-Azure AI services provide each container with a common configuration framework. You can easily configure your Translator containers to build Translator application architecture optimized for robust cloud capabilities and edge locality.

-The **Translator** container runtime environment is configured using the `docker run` command arguments. This container has both required and optional settings. The required container-specific settings are the billing settings.

-## Configuration settings

-The container has the following configuration settings:

-|Required|Setting|Purpose|

-|--|--|--|

-|Yes|[ApiKey](#apikey-configuration-setting)|Tracks billing information.|

-|No|[ApplicationInsights](#applicationinsights-setting)|Enables adding [Azure Application Insights](/azure/application-insights) telemetric support to your container.|

-|Yes|[Billing](#billing-configuration-setting)|Specifies the endpoint URI of the service resource on Azure.|

-|Yes|[EULA](#eula-setting)| Indicates that you've accepted the license for the container.|

-|No|[Fluentd](#fluentd-settings)|Writes log and, optionally, metric data to a Fluentd server.|

-|No|HTTP Proxy|Configures an HTTP proxy for making outbound requests.|

-|No|[Logging](#logging-settings)|Provides ASP.NET Core logging support for your container. |

-|Yes|[Mounts](#mount-settings)|Reads and writes data from the host computer to the container and from the container back to the host computer.|

- > [!IMPORTANT]

-> The [**ApiKey**](#apikey-configuration-setting), [**Billing**](#billing-configuration-setting), and [**EULA**](#eula-setting) settings are used together, and you must provide valid values for all three of them; otherwise your container won't start. For more information about using these configuration settings to instantiate a container.

-## ApiKey configuration setting

-The `ApiKey` setting specifies the Azure resource key used to track billing information for the container. You must specify a value for the ApiKey and the value must be a valid key for the _Translator_ resource specified for the [`Billing`](#billing-configuration-setting) configuration setting.

-This setting can be found in the following place:

-* Azure portal: **Translator** resource management, under **Keys**

-## ApplicationInsights setting

-## Billing configuration setting

-The `Billing` setting specifies the endpoint URI of the _Translator_ resource on Azure used to meter billing information for the container. You must specify a value for this configuration setting, and the value must be a valid endpoint URI for a _Translator_ resource on Azure. The container reports usage about every 10 to 15 minutes.

-This setting can be found in the following place:

-* Azure portal: **Translator** Overview page labeled `Endpoint`

-| Required | Name | Data type | Description |

-| -- | - | | -- |

-| Yes | `Billing` | String | Billing endpoint URI. For more information on obtaining the billing URI, see [gathering required parameters](translator-how-to-install-container.md#required-elements). For more information and a complete list of regional endpoints, see [Custom subdomain names for Azure AI services](../../cognitive-services-custom-subdomains.md). |

-## EULA setting

-## Fluentd settings

-## HTTP/HTTPS proxy credentials settings

-If you need to configure an HTTP proxy for making outbound requests, use these two arguments:

-| Name | Data type | Description |

-|--|--|--|

-|HTTPS_PROXY|string|The proxy to use, for example, `https://proxy:8888`<br>`<proxy-url>`|

-|HTTP_PROXY_CREDS|string|Any credentials needed to authenticate against the proxy, for example, `username:password`. This value **must be in lower-case**. |

-|`<proxy-user>`|string|The user for the proxy.|

-|`<proxy-password>`|string|The password associated with `<proxy-user>` for the proxy.|

-||||

-```bash

-docker run --rm -it -p 5000:5000 \

-<registry-location>/<image-name> \

-Eula=accept \

-Billing=<endpoint> \

-ApiKey=<api-key> \

-HTTPS_PROXY=<proxy-url> \

-HTTP_PROXY_CREDS=<proxy-user>:<proxy-password> \

-```

-## Logging settings

-Translator containers support the following logging providers:

-|Provider|Purpose|

-|--|--|

-|[Console](/aspnet/core/fundamentals/logging/#console-provider)|The ASP.NET Core `Console` logging provider. All of the ASP.NET Core configuration settings and default values for this logging provider are supported.|

-|[Debug](/aspnet/core/fundamentals/logging/#debug-provider)|The ASP.NET Core `Debug` logging provider. All of the ASP.NET Core configuration settings and default values for this logging provider are supported.|

-|[Disk](#disk-logging)|The JSON logging provider. This logging provider writes log data to the output mount.|

-* The `Logging` settings manage ASP.NET Core logging support for your container. You can use the same configuration settings and values for your container that you use for an ASP.NET Core application.

-* The `Logging.LogLevel` specifies the minimum level to log. The severity of the `LogLevel` ranges from 0 to 6. When a `LogLevel` is specified, logging is enabled for messages at the specified level and higher: Trace = 0, Debug = 1, Information = 2, Warning = 3, Error = 4, Critical = 5, None = 6.

-* Currently, Translator containers have the ability to restrict logs at the **Warning** LogLevel or higher.

-The general command syntax for logging is as follows:

-```bash

- -Logging:LogLevel:{Provider}={FilterSpecs}

-```

-The following command starts the Docker container with the `LogLevel` set to **Warning** and logging provider set to **Console**. This command prints anomalous or unexpected events during the application flow to the console:

-```bash

-docker run --rm -it -p 5000:5000

-mcr.microsoft.com/azure-cognitive-services/translator/text-translation:latest

-```

-### Disk logging

-The `Disk` logging provider supports the following configuration settings:

-| Name | Data type | Description |

-||--|-|

-| `Format` | String | The output format for log files.<br/> **Note:** This value must be set to `json` to enable the logging provider. If this value is specified without also specifying an output mount while instantiating a container, an error occurs. |

-| `MaxFileSize` | Integer | The maximum size, in megabytes (MB), of a log file. When the size of the current log file meets or exceeds this value, the logging provider starts a new log file. If -1 is specified, the size of the log file is limited only by the maximum file size, if any, for the output mount. The default value is 1. |

-#### Disk provider example

-```bash

-docker run --rm -it -p 5000:5000 \

-Eula=accept \

-Billing=<endpoint> \

-ApiKey=<api-key> \

-Logging:Disk:Format=json \

-Mounts:Output=/output

-```

-For more information about configuring ASP.NET Core logging support, see [Settings file configuration](/aspnet/core/fundamentals/logging/).

-## Mount settings

-Use bind mounts to read and write data to and from the container. You can specify an input mount or output mount by specifying the `--mount` option in the [docker run](https://docs.docker.com/engine/reference/commandline/run/) command.

-#

-# Container: Translate

-Translate text.

-## Request URL

-Send a `POST` request to:

-```HTTP

-http://localhost:{port}/translate?api-version=3.0

-```

-Example: http://<span></span>localhost:5000/translate?api-version=3.0

-## Request parameters

-Request parameters passed on the query string are:

-### Required parameters

-| Query parameter | Description |

-| | |

-| api-version | _Required parameter_. <br>Version of the API requested by the client. Value must be `3.0`. |

-| from | _Required parameter_. <br>Specifies the language of the input text. Find which languages are available to translate from by looking up [supported languages](../reference/v3-0-languages.md) using the `translation` scope.|

-| to | _Required parameter_. <br>Specifies the language of the output text. The target language must be one of the [supported languages](../reference/v3-0-languages.md) included in the `translation` scope. For example, use `to=de` to translate to German. <br>It's possible to translate to multiple languages simultaneously by repeating the parameter in the query string. For example, use `to=de&to=it` to translate to German and Italian. |

-### Optional parameters

-| Query parameter | Description |

-| | |

-| textType | _Optional parameter_. <br>Defines whether the text being translated is plain text or HTML text. Any HTML needs to be a well-formed, complete element. Possible values are: `plain` (default) or `html`. |

-| includeSentenceLength | _Optional parameter_. <br>Specifies whether to include sentence boundaries for the input text and the translated text. Possible values are: `true` or `false` (default). |

-Request headers include:

-| Headers | Description |

-| | |

-| Authentication header(s) | _Required request header_. <br>See [available options for authentication](../reference/v3-0-reference.md#authentication). |

-| Content-Type | _Required request header_. <br>Specifies the content type of the payload. <br>Accepted value is `application/json; charset=UTF-8`. |

-| Content-Length | _Required request header_. <br>The length of the request body. |

-| X-ClientTraceId | _Optional_. <br>A client-generated GUID to uniquely identify the request. You can omit this header if you include the trace ID in the query string using a query parameter named `ClientTraceId`. |

-## Request body

-The body of the request is a JSON array. Each array element is a JSON object with a string property named `Text`, which represents the string to translate.

-```json

-[

- {"Text":"I would really like to drive your car around the block a few times."}

-]

-```

-The following limitations apply:

-* The array can have at most 100 elements.

-* The entire text included in the request can't exceed 10,000 characters including spaces.

-## Response body

-A successful response is a JSON array with one result for each string in the input array. A result object includes the following properties:

-* `translations`: An array of translation results. The size of the array matches the number of target languages specified through the `to` query parameter. Each element in the array includes:

-* `to`: A string representing the language code of the target language.

-* `text`: A string giving the translated text.

-* `sentLen`: An object returning sentence boundaries in the input and output texts.

-* `srcSentLen`: An integer array representing the lengths of the sentences in the input text. The length of the array is the number of sentences, and the values are the length of each sentence.

-* `transSentLen`: An integer array representing the lengths of the sentences in the translated text. The length of the array is the number of sentences, and the values are the length of each sentence.

- Sentence boundaries are only included when the request parameter `includeSentenceLength` is `true`.

- * `sourceText`: An object with a single string property named `text`, which gives the input text in the default script of the source language. `sourceText` property is present only when the input is expressed in a script that's not the usual script for the language. For example, if the input were Arabic written in Latin script, then `sourceText.text` would be the same Arabic text converted into Arab script.

-Examples of JSON responses are provided in the [examples](#examples) section.

-## Response headers

-| Headers | Description |

-| | |

-| X-RequestId | Value generated by the service to identify the request. It's used for troubleshooting purposes. |

-| X-MT-System | Specifies the system type that was used for translation for each 'to' language requested for translation. The value is a comma-separated list of strings. Each string indicates a type: </br></br>&FilledVerySmallSquare; Custom - Request includes a custom system and at least one custom system was used during translation.</br>&FilledVerySmallSquare; Team - All other requests |

-## Response status codes

-If an error occurs, the request will also return a JSON error response. The error code is a 6-digit number combining the 3-digit HTTP status code followed by a 3-digit number to further categorize the error. Common error codes can be found on the [v3 Translator reference page](../reference/v3-0-reference.md#errors).

-## Examples

-### Translate a single input

-This example shows how to translate a single sentence from English to Simplified Chinese.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'Hello, what is your name?'}]"

-```

-The response body is:

-```

-[

- {

- "translations":[

- {"text":"你好, 你叫什么名字？","to":"zh-Hans"}

- ]

- }

-]

-```

-The `translations` array includes one element, which provides the translation of the single piece of text in the input.

-### Translate multiple pieces of text

-Translating multiple strings at once is simply a matter of specifying an array of strings in the request body.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'Hello, what is your name?'}, {'Text':'I am fine, thank you.'}]"

-```

-The response contains the translation of all pieces of text in the exact same order as in the request.

-The response body is:

-```

-[

- {

- "translations":[

- {"text":"你好, 你叫什么名字？","to":"zh-Hans"}

- ]

- },

- {

- "translations":[

- {"text":"我很好，谢谢你。","to":"zh-Hans"}

- ]

- }

-]

-```

-### Translate to multiple languages

-This example shows how to translate the same input to several languages in one request.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans&to=de" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'Hello, what is your name?'}]"

-```

-The response body is:

-```

-[

- {

- "translations":[

- {"text":"你好, 你叫什么名字？","to":"zh-Hans"},

- {"text":"Hallo, was ist dein Name?","to":"de"}

- ]

- }

-]

-```

-### Translate content with markup and decide what's translated

-It's common to translate content that includes markup such as content from an HTML page or content from an XML document. Include query parameter `textType=html` when translating content with tags. In addition, it's sometimes useful to exclude specific content from translation. You can use the attribute `class=notranslate` to specify content that should remain in its original language. In the following example, the content inside the first `div` element won't be translated, while the content in the second `div` element will be translated.

-```

-<div class="notranslate">This will not be translated.</div>

-<div>This will be translated. </div>

-```

-Here's a sample request to illustrate.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans&textType=html" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'<div class=\"notranslate\">This will not be translated.</div><div>This will be translated.</div>'}]"

-```

-The response is:

-```

-[

- {

- "translations":[

- {"text":"<div class=\"notranslate\">This will not be translated.</div><div>这将被翻译。</div>","to":"zh-Hans"}

- ]

- }

-]

-```

-### Translate with dynamic dictionary

-If you already know the translation you want to apply to a word or a phrase, you can supply it as markup within the request. The dynamic dictionary is only safe for proper nouns such as personal names and product names.

-The markup to supply uses the following syntax.

-```

-<mstrans:dictionary translation="translation of phrase">phrase</mstrans:dictionary>

-```

-For example, consider the English sentence "The word wordomatic is a dictionary entry." To preserve the word _wordomatic_ in the translation, send the request:

-```

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=de" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'The word <mstrans:dictionary translation=\"wordomatic\">word or phrase</mstrans:dictionary> is a dictionary entry.'}]"

-```

-The result is:

-```

-[

- {

- "translations":[

- {"text":"Das Wort \"wordomatic\" ist ein W├╢rterbucheintrag.","to":"de"}

- ]

- }

-]

-```

-This feature works the same way with `textType=text` or with `textType=html`. The feature should be used sparingly. The appropriate and far better way of customizing translation is by using Custom Translator. Custom Translator makes full use of context and statistical probabilities. If you've created training data that shows your work or phrase in context, you'll get much better results. [Learn more about Custom Translator](../custom-translator/concepts/customization.md).

-## Request limits

-Each translate request is limited to 10,000 characters, across all the target languages you're translating to. For example, sending a translate request of 3,000 characters to translate to three different languages results in a request size of 3000x3 = 9,000 characters, which satisfy the request limit. You're charged per character, not by the number of requests. It's recommended to send shorter requests.

-The following table lists array element and character limits for the Translator **translation** operation.

-| Operation | Maximum size of array element | Maximum number of array elements | Maximum request size (characters) |

-|:-|:-|:-|:-|

-| translate | 10,000 | 100 | 10,000 |

-<!-- markdownlint-disable MD036 -->

-<!-- markdownlint-disable MD001 -->

-# Use Translator containers in disconnected environments

- Azure AI Translator containers allow you to use Translator Service APIs with the benefits of containerization. Disconnected containers are offered through commitment tier pricing offered at a discounted rate compared to pay-as-you-go pricing. With commitment tier pricing, you can commit to using Translator Service features for a fixed fee, at a predictable total cost, based on the needs of your workload.

-## Get started

-Before attempting to run a Docker container in an offline environment, make sure you're familiar with the following requirements to successfully download and use the container:

-* Host computer requirements and recommendations.

-* The Docker `pull` command to download the container.

-* How to validate that a container is running.

-* How to send queries to the container's endpoint, once it's running.

-## Request access to use containers in disconnected environments

-Complete and submit the [request form](https://aka.ms/csdisconnectedcontainers) to request access to the containers disconnected from the Internet.

-Access is limited to customers that meet the following requirements:

-* Your organization should be identified as strategic customer or partner with Microsoft.

-* Disconnected containers are expected to run fully offline, hence your use cases must meet at least one of these or similar requirements:

- * Environment or device(s) with zero connectivity to internet.

- * Remote location that occasionally has internet access.

- * Organization under strict regulation of not sending any kind of data back to cloud.

-* Application completed as instructed. Make certain to pay close attention to guidance provided throughout the application to ensure you provide all the necessary information required for approval.

-## Create a new resource and purchase a commitment plan

-1. Create a [Translator resource](https://portal.azure.com/#create/Microsoft.CognitiveServicesTextTranslation) in the Azure portal.

-1. Enter the applicable information to create your resource. Be sure to select **Commitment tier disconnected containers** as your pricing tier.

- > [!NOTE]

- >

- > * You will only see the option to purchase a commitment tier if you have been approved by Microsoft.

- :::image type="content" source="../media/create-resource-offline-container.png" alt-text="A screenshot showing resource creation on the Azure portal.":::

-1. Select **Review + Create** at the bottom of the page. Review the information, and select **Create**.

-## Gather required parameters

-There are three required parameters for all Azure AI services' containers:

-* The end-user license agreement (EULA) must be present with a value of *accept*.

-* The endpoint URL for your resource from the Azure portal.

-* The API key for your resource from the Azure portal.

-Both the endpoint URL and API key are needed when you first run the container to configure it for disconnected usage. You can find the key and endpoint on the **Key and endpoint** page for your resource in the Azure portal:

- :::image type="content" source="../media/quickstarts/keys-and-endpoint-portal.png" alt-text="Screenshot of Azure portal keys and endpoint page.":::

-> [!IMPORTANT]

-> You will only use your key and endpoint to configure the container to run in a disconnected environment. After you configure the container, you won't need the key and endpoint values to send API requests. Store them securely, for example, using Azure Key Vault. Only one key is necessary for this process.

-## Download a Docker container with `docker pull`

-Download the Docker container that has been approved to run in a disconnected environment. For example:

-|Docker pull command | Value |Format|

-|-|-||

-|&bullet; **`docker pull [image]`**</br>&bullet; **`docker pull [image]:latest`**|The latest container image.|&bullet; mcr.microsoft.com/azure-cognitive-services/translator/text-translation</br> </br>&bullet; mcr.microsoft.com/azure-cognitive-services/translator/text-translation: latest |

-|||

-|&bullet; **`docker pull [image]:[version]`** | A specific container image |mcr.microsoft.com/azure-cognitive-services/translator/text-translation:1.0.019410001-amd64 |

- **Example Docker pull command**

-```docker

-docker pull mcr.microsoft.com/azure-cognitive-services/translator/text-translation:latest

-```

-## Configure the container to run in a disconnected environment

-Now that you've downloaded your container, you need to execute the `docker run` command with the following parameters:

-* **`DownloadLicense=True`**. This parameter downloads a license file that enables your Docker container to run when it isn't connected to the internet. It also contains an expiration date, after which the license file is invalid to run the container. You can only use the license file in corresponding approved container.

-* **`Languages={language list}`**. You must include this parameter to download model files for the [languages](../language-support.md) you want to translate.

-> [!IMPORTANT]

-> The `docker run` command will generate a template that you can use to run the container. The template contains parameters you'll need for the downloaded models and configuration file. Make sure you save this template.

-The following example shows the formatting for the `docker run` command with placeholder values. Replace these placeholder values with your own values.

-| Placeholder | Value | Format|

-|-|-||

-| `[image]` | The container image you want to use. | `mcr.microsoft.com/azure-cognitive-services/translator/text-translation` |

-| `{LICENSE_MOUNT}` | The path where the license is downloaded, and mounted. | `/host/license:/path/to/license/directory` |

- | `{MODEL_MOUNT_PATH}`| The path where the machine translation models are downloaded, and mounted. Your directory structure must be formatted as **/usr/local/models** | `/host/translator/models:/usr/local/models`|

-| `{ENDPOINT_URI}` | The endpoint for authenticating your service request. You can find it on your resource's **Key and endpoint** page, in the Azure portal. | `https://<your-custom-subdomain>.cognitiveservices.azure.com` |

-| `{API_KEY}` | The key for your Text Translation resource. You can find it on your resource's **Key and endpoint** page, in the Azure portal. |`{string}`|

-| `{LANGUAGES_LIST}` | List of language codes separated by commas. It's mandatory to have English (en) language as part of the list.| `en`, `fr`, `it`, `zu`, `uk` |

-| `{CONTAINER_LICENSE_DIRECTORY}` | Location of the license folder on the container's local filesystem. | `/path/to/license/directory` |

- **Example `docker run` command**

-```docker

-docker run --rm -it -p 5000:5000 \

-[image]

-```

-### Translator translation models and container configuration

-After you've [configured the container](#configure-the-container-to-run-in-a-disconnected-environment), the values for the downloaded translation models and container configuration will be generated and displayed in the container output:

-```bash

- -e MODELS= usr/local/models/model1/, usr/local/models/model2/

- -e TRANSLATORSYSTEMCONFIG=/usr/local/models/Config/5a72fa7c-394b-45db-8c06-ecdfc98c0832

-```

-## Run the container in a disconnected environment

-Once the license file has been downloaded, you can run the container in a disconnected environment with your license, appropriate memory, and suitable CPU allocations. The following example shows the formatting of the `docker run` command with placeholder values. Replace these placeholders values with your own values.

-Whenever the container is run, the license file must be mounted to the container and the location of the license folder on the container's local filesystem must be specified with `Mounts:License=`. In addition, an output mount must be specified so that billing usage records can be written.

-Placeholder | Value | Format|

-|-|-||

-| `[image]`| The container image you want to use. | `mcr.microsoft.com/azure-cognitive-services/translator/text-translation` |

- `{MEMORY_SIZE}` | The appropriate size of memory to allocate for your container. | `16g` |

-| `{NUMBER_CPUS}` | The appropriate number of CPUs to allocate for your container. | `4` |

-| `{LICENSE_MOUNT}` | The path where the license is located and mounted. | `/host/translator/license:/path/to/license/directory` |

-|`{MODEL_MOUNT_PATH}`| The path where the machine translation models are downloaded, and mounted. Your directory structure must be formatted as **/usr/local/models** | `/host/translator/models:/usr/local/models`|

-|`{MODELS_DIRECTORY_LIST}`|List of comma separated directories each having a machine translation model. | `/usr/local/models/enu_esn_generalnn_2022240501,/usr/local/models/esn_enu_generalnn_2022240501` |

-| `{OUTPUT_PATH}` | The output path for logging [usage records](#usage-records). | `/host/output:/path/to/output/directory` |

-| `{CONTAINER_LICENSE_DIRECTORY}` | Location of the license folder on the container's local filesystem. | `/path/to/license/directory` |

-| `{CONTAINER_OUTPUT_DIRECTORY}` | Location of the output folder on the container's local filesystem. | `/path/to/output/directory` |

-|`{TRANSLATOR_CONFIG_JSON}`| Translator system configuration file used by container internally.| `/usr/local/models/Config/5a72fa7c-394b-45db-8c06-ecdfc98c0832` |

- **Example `docker run` command**

-```docker

-docker run --rm -it -p 5000:5000 --memory {MEMORY_SIZE} --cpus {NUMBER_CPUS} \

-[image]

-```

-## Other parameters and commands

-Here are a few more parameters and commands you may need to run the container:

-#### Usage records

-When operating Docker containers in a disconnected environment, the container will write usage records to a volume where they're collected over time. You can also call a REST API endpoint to generate a report about service usage.

-#### Arguments for storing logs

-When run in a disconnected environment, an output mount must be available to the container to store usage logs. For example, you would include `-v /host/output:{OUTPUT_PATH}` and `Mounts:Output={OUTPUT_PATH}` in the following example, replacing `{OUTPUT_PATH}` with the path where the logs are stored:

- **Example `docker run` command**

-```docker

-docker run -v /host/output:{OUTPUT_PATH} ... <image> ... Mounts:Output={OUTPUT_PATH}

-```

-#### Environment variable names in Kubernetes deployments

-Some Azure AI Containers, for example Translator, require users to pass environmental variable names that include colons (`:`) when running the container. This will work fine when using Docker, but Kubernetes does not accept colons in environmental variable names.

-To resolve this, you can replace colons with two underscore characters (`__`) when deploying to Kubernetes. See the following example of an acceptable format for environmental variable names:

-```Kubernetes

- env:

- - name: Mounts__License

- value: "/license"

- - name: Mounts__Output

- value: "/output"

-```

-This example replaces the default format for the `Mounts:License` and `Mounts:Output` environment variable names in the docker run command.

-#### Get records using the container endpoints

-The container provides two endpoints for returning records regarding its usage.

-#### Get all records

-The following endpoint provides a report summarizing all of the usage collected in the mounted billing record directory.

-```HTTP

-https://<service>/records/usage-logs/

-```

- **Example HTTPS endpoint**

- `http://localhost:5000/records/usage-logs`

-The usage-logs endpoint returns a JSON response similar to the following example:

-```json

-{

-"apiType": "string",

-"serviceName": "string",

-"meters": [

-{

- "name": "string",

- "quantity": 256345435

- }

- ]

-}

-```

-#### Get records for a specific month

-The following endpoint provides a report summarizing usage over a specific month and year:

-```HTTP

-https://<service>/records/usage-logs/{MONTH}/{YEAR}

-```

-This usage-logs endpoint returns a JSON response similar to the following example:

-```json

-{

- "apiType": "string",

- "serviceName": "string",

- "meters": [

- {

- "name": "string",

- "quantity": 56097

- }

- ]

-}

-```

-### Purchase a different commitment plan for disconnected containers

-Commitment plans for disconnected containers have a calendar year commitment period. When you purchase a plan, you're charged the full price immediately. During the commitment period, you can't change your commitment plan, however you can purchase more unit(s) at a pro-rated price for the remaining days in the year. You have until midnight (UTC) on the last day of your commitment, to end a commitment plan.

-You can choose a different commitment plan in the **Commitment tier pricing** settings of your resource under the **Resource Management** section.

-### End a commitment plan

- If you decide that you don't want to continue purchasing a commitment plan, you can set your resource's autorenewal to **Do not auto-renew**. Your commitment plan expires on the displayed commitment end date. After this date, you won't be charged for the commitment plan. You're still able to continue using the Azure resource to make API calls, charged at pay-as-you-go pricing. You have until midnight (UTC) on the last day of the year to end a commitment plan for disconnected containers. If you do so, you avoid charges for the following year.

-## Troubleshooting

-Run the container with an output mount and logging enabled. These settings enable the container to generate log files that are helpful for troubleshooting issues that occur while starting or running the container.

-Translator container enables you to build a translator application architecture that is optimized for both robust cloud capabilities and edge locality.

-See the list of [languages supported](../language-support.md) when using Translator containers.

-> [!IMPORTANT]

->

-> * To use the Translator container, you must submit an online request and have it approved. For more information, _see_ [Request approval to run container](#request-approval-to-run-container).

-> * Translator container supports limited features compared to the cloud offerings. For more information, _see_ [**Container translate methods**](translator-container-supported-parameters.md).

-<!-- markdownlint-disable MD033 -->

-## Prerequisites

-To get started, you need an active [**Azure account**](https://azure.microsoft.com/free/cognitive-services/). If you don't have one, you can [**create a free account**](https://azure.microsoft.com/free/).

-You also need:

-| Required | Purpose |

-|--|--|

-| Familiarity with Docker | <ul><li>You should have a basic understanding of Docker concepts like registries, repositories, containers, and container images, as well as knowledge of basic `docker` [terminology and commands](/dotnet/architecture/microservices/container-docker-introduction/docker-terminology).</li></ul> |

-| Docker Engine | <ul><li>You need the Docker Engine installed on a [host computer](#host-computer). Docker provides packages that configure the Docker environment on [macOS](https://docs.docker.com/docker-for-mac/), [Windows](https://docs.docker.com/docker-for-windows/), and [Linux](https://docs.docker.com/engine/installation/#supported-platforms). For a primer on Docker and container basics, see the [Docker overview](https://docs.docker.com/engine/docker-overview/).</li><li> Docker must be configured to allow the containers to connect with and send billing data to Azure. </li><li> On **Windows**, Docker must also be configured to support **Linux** containers.</li></ul> |

-| Translator resource | <ul><li>An Azure [Translator](https://portal.azure.com/#create/Microsoft.CognitiveServicesTextTranslation) regional resource (not `global`) with an associated API key and endpoint URI. Both values are required to start the container and can be found on the resource overview page.</li></ul>|

-|Optional|Purpose|

-||-|

-|Azure CLI (command-line interface) |<ul><li> The [Azure CLI](/cli/azure/install-azure-cli) enables you to use a set of online commands to create and manage Azure resources. It's available to install in Windows, macOS, and Linux environments and can be run in a Docker container and Azure Cloud Shell.</li></ul> |

-## Required elements

-All Azure AI containers require three primary elements:

-* **EULA accept setting**. An end-user license agreement (EULA) set with a value of `Eula=accept`.

-* **API key** and **Endpoint URL**. The API key is used to start the container. You can retrieve the API key and Endpoint URL values by navigating to the Translator resource **Keys and Endpoint** page and selecting the `Copy to clipboard` <span class="docon docon-edit-copy x-hidden-focus"></span> icon.

-> [!IMPORTANT]

->

-> * Keys are used to access your Azure AI resource. Do not share your keys. Store them securely, for example, using Azure Key Vault. We also recommend regenerating these keys regularly. Only one key is necessary to make an API call. When regenerating the first key, you can use the second key for continued access to the service.

-## Host computer

-## Container requirements and recommendations

-The following table describes the minimum and recommended CPU cores and memory to allocate for the Translator container.

-| Container | Minimum |Recommended | Language Pair |

-|--|||-|

-| Translator |`2` cores, `4 GB` memory |`4` cores, `8 GB` memory | 2 |

-* Each core must be at least 2.6 gigahertz (GHz) or faster.

-* The core and memory correspond to the `--cpus` and `--memory` settings, which are used as part of the `docker run` command.

-> [!NOTE]

->

-> * CPU core and memory correspond to the `--cpus` and `--memory` settings, which are used as part of the docker run command.

->

-> * The minimum and recommended specifications are based on Docker limits, not host machine resources.

-## Request approval to run container

-Complete and submit the [**Azure AI services

-Application for Gated Services**](https://aka.ms/csgate-translator) to request access to the container.

-## Translator container image

-The Translator container image can be found on the `mcr.microsoft.com` container registry syndicate. It resides within the `azure-cognitive-services/translator` repository and is named `text-translation`. The fully qualified container image name is `mcr.microsoft.com/azure-cognitive-services/translator/text-translation:latest`.

-To use the latest version of the container, you can use the `latest` tag. You can find a full list of [tags on the MCR](https://mcr.microsoft.com/product/azure-cognitive-services/translator/text-translation/tags).

-## Get container images with **docker commands**

-> [!IMPORTANT]

->

-> * The docker commands in the following sections use the back slash, `\`, as a line continuation character. Replace or remove this based on your host operating system's requirements.

-> * The `EULA`, `Billing`, and `ApiKey` options must be specified to run the container; otherwise, the container won't start.

-Use the [docker run](https://docs.docker.com/engine/reference/commandline/run/) command to download a container image from Microsoft Container registry and run it.

-```Docker

-docker run --rm -it -p 5000:5000 --memory 12g --cpus 4 \

-mcr.microsoft.com/azure-cognitive-services/translator/text-translation:latest

-```

-The above command:

-* Downloads and runs a Translator container from the container image.

-* Allocates 12 gigabytes (GB) of memory and four CPU core.

-* Exposes TCP port 5000 and allocates a pseudo-TTY for the container

-* Accepts the end-user agreement (EULA)

-* Configures billing endpoint

-* Downloads translation models for languages English, French, Spanish, Arabic, and Russian

-* Automatically removes the container after it exits. The container image is still available on the host computer.

-### Run multiple containers on the same host

-If you intend to run multiple containers with exposed ports, make sure to run each container with a different exposed port. For example, run the first container on port 5000 and the second container on port 5001.

-You can have this container and a different Azure AI container running on the HOST together. You also can have multiple containers of the same Azure AI container running.

-## Query the container's Translator endpoint

- The container provides a REST-based Translator endpoint API. Here's an example request:

-```curl

-curl -X POST "http://localhost:5000/translate?api-version=3.0&from=en&to=zh-HANS"

- -H "Content-Type: application/json" -d "[{'Text':'Hello, what is your name?'}]"

-```

-> [!NOTE]

-> If you attempt the cURL POST request before the container is ready, you'll end up getting a *Service is temporarily unavailable* response. Wait until the container is ready, then try again.

-## Stop the container

-## Troubleshoot

-### Validate that a container is running

-There are several ways to validate that the container is running:

-* The container provides a homepage at `/` as a visual validation that the container is running.

-* You can open your favorite web browser and navigate to the external IP address and exposed port of the container in question. Use the following request URLs to validate the container is running. The example request URLs listed point to `http://localhost:5000`, but your specific container may vary. Keep in mind that you're navigating to your container's **External IP address** and exposed port.

-| Request URL | Purpose |

-|--|--|

-| `http://localhost:5000/` | The container provides a home page. |

-| `http://localhost:5000/ready` | Requested with GET. Provides a verification that the container is ready to accept a query against the model. This request can be used for Kubernetes [liveness and readiness probes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/). |

-| `http://localhost:5000/status` | Requested with GET. Verifies if the api-key used to start the container is valid without causing an endpoint query. This request can be used for Kubernetes [liveness and readiness probes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/). |

-| `http://localhost:5000/swagger` | The container provides a full set of documentation for the endpoints and a **Try it out** feature. With this feature, you can enter your settings into a web-based HTML form and make the query without having to write any code. After the query returns, an example CURL command is provided to demonstrate the HTTP headers and body format that's required. |

-## Text translation code samples

-description: Learn how to create an Azure AI Translator resource and retrieve your API key and endpoint URL in the Azure portal.

-#

-# Create a Translator resource

-In this article, you learn how to create a Translator resource in the Azure portal. [Azure AI Translator](translator-overview.md) is a cloud-based machine translation service that is part of the [Azure AI services](../what-are-ai-services.md) family. Azure resources are instances of services that you create. All API requests to Azure AI services require an *endpoint* URL and a read-only *key* for authenticating access.

-## Prerequisites

-To get started, you need an active [**Azure account**](https://azure.microsoft.com/free/cognitive-services/). If you don't have one, you can [**create a free 12-month subscription**](https://azure.microsoft.com/free/).

-## Create your resource

-With your Azure account, you can access the Translator service through two different resource types:

-* [**Single-service**](https://portal.azure.com/#create/Microsoft.CognitiveServicesTextTranslation) resource types enable access to a single service API key and endpoint.

-* [**Multi-service**](https://portal.azure.com/#create/Microsoft.CognitiveServicesAllInOne) resource types enable access to multiple Azure AI services by using a single API key and endpoint.

-## Complete your project and instance details

-After you decide which resource type you want use to access the Translator service, you can enter the details for your project and instance.

-1. **Subscription**. Select one of your available Azure subscriptions.

-1. **Resource Group**. You can create a new resource group or add your resource to a pre-existing resource group that shares the same lifecycle, permissions, and policies.

-1. **Resource Region**. Choose **Global** unless your business or application requires a specific region. If you're planning on using the Document Translation feature with [managed identity authorization](document-translation/how-to-guides/create-use-managed-identities.md), choose a geographic region such as **East US**.

-1. **Name**. Enter a name for your resource. The name you choose must be unique within Azure.

- > [!NOTE]

- > If you're using a Translator feature that requires a custom domain endpoint, such as Document Translation, the value that you enter in the Name field will be the custom domain name parameter for the endpoint.

-1. **Pricing tier**. Select a [pricing tier](https://azure.microsoft.com/pricing/details/cognitive-services/translator) that meets your needs:

- * Each subscription has a free tier.

- * The free tier has the same features and functionality as the paid plans and doesn't expire.

- * Only one free tier resource is available per subscription.

- * Document Translation is supported in paid tiers. The Language Studio only supports the S1 or D3 instance tiers. If you just want to try Document Translation, select the Standard S1 instance tier.

-1. If you've created a multi-service resource, the links at the bottom of the **Basics** tab provides technical documentation regarding the appropriate operation of the service.

-1. Select **Review + Create**.

-1. Review the service terms, and select **Create** to deploy your resource.

-1. After your resource has successfully deployed, select **Go to resource**.

-### Authentication keys and endpoint URL

-All Azure AI services API requests require an endpoint URL and a read-only key for authentication.

-* **Authentication keys**. Your key is a unique string that is passed on every request to the Translation service. You can pass your key through a query-string parameter or by specifying it in the HTTP request header.

-* **Endpoint URL**. Use the Global endpoint in your API request unless you need a specific Azure region or custom endpoint. For more information, see [Base URLs](reference/v3-0-reference.md#base-urls). The Global endpoint URL is `api.cognitive.microsofttranslator.com`.

-## Get your authentication keys and endpoint

-To authenitcate your connection to your Translator resource, you'll need to find its keys and endpoint.

-1. After your new resource deploys, select **Go to resource** or go to your resource page.

-1. In the left navigation pane, under **Resource Management**, select **Keys and Endpoint**.

-1. Copy and paste your keys and endpoint URL in a convenient location, such as Notepad.

-## Create a Text Translation client

-Text Translation supports both [global and regional endpoints](#complete-your-project-and-instance-details). Once you have your [authentication keys](#authentication-keys-and-endpoint-url), you need to create an instance of the `TextTranslationClient`, using an `AzureKeyCredential` for authentication, to interact with the Text Translation service:

-* To create a `TextTranslationClient` using a global resource endpoint, you need your resource **API key**:

- ```bash

- AzureKeyCredential credential = new('<apiKey>');

- TextTranslationClient client = new(credential);

- ```

-* To create a `TextTranslationClient` using a regional resource endpoint, you need your resource **API key** and the name of the **region** where your resource is located:

- ```bash

- AzureKeyCredential credential = new('<apiKey>');

- TextTranslationClient client = new(credential, '<region>');

- ```

-## How to delete a resource or resource group

-> [!WARNING]

->

-> Deleting a resource group also deletes all resources contained in the group.

-To delete the resource:

-1. Search and select **Resource groups** in the Azure portal, and select your resource group.

-1. Select the resources to be deleted by selecting the adjacent check box.

-1. Select **Delete** from the top menu near the right edge.

-1. Enter *delete* in the **Delete Resources** dialog box.

-1. Select **Delete**.

-To delete the resource group:

-1. Go to your Resource Group in the Azure portal.

-1. Select **Delete resource group** from the top menu bar.

-1. Confirm the deletion request by entering the resource group name and selecting **Delete**.

-## How to get started with Azure AI Translator REST APIs

-In our quickstart, you learn how to use the Translator service with REST APIs.

-For more information, *see* [how to create a Translator resource](../create-translator-resource.md).

-description: Get answers to frequently asked questions about Document Translation.

-When text is translated from the source to target language, the overall length of translated text can differ from source. The result could be reflow of text across pages. The same fonts aren't always available in both source and target language. In general, the same font style is applied in target language to retain formatting closer to source.

-No. The text in an image within a document isn't translated.

-No. The service can't translate encrypted or password-protected documents. If your scanned or text-embedded PDFs are password-locked, you must remove the lock before submission.

-No. Don't include SAS token-appended URLS. Managed identities eliminate the need for you to include shared access signature tokens (SAS) with your HTTP requests.

-* A brief understanding of [**Azure role-based access control (`Azure RBAC`)**](../../../../role-based-access-control/role-assignments-portal.md) using the Azure portal.

-* Once you have your Azure subscription, create a [Translator resource](create-translator-resource.md) in the [Azure portal](https://portal.azure.com/#create/Microsoft.CognitiveServicesTextTranslation).

-* [**How-to guides**](create-translator-resource.md). Instructions for accessing and using the service in more specific or customized ways.

-* [**Create a Translator resource**](create-translator-resource.md "Go to the Azure portal.") in the Azure portal.

-* [**Get your access keys and API endpoint**](create-translator-resource.md#authentication-keys-and-endpoint-url). An endpoint URL and read-only key are required for authentication.

-Now, you're ready to get started! [**Create a Translator service**](create-translator-resource.md "Go to the Azure portal."), [**get your access keys and API endpoint**](create-translator-resource.md#authentication-keys-and-endpoint-url "An endpoint URL and read-only key are required for authentication."), and try our [**quickstart**](quickstart-text-rest-api.md "Learn to use Translator via REST.").

-In the Azure AI Studio, there are two levels of access: the Azure AI hub resource and the Azure AI project. The resource is home to the infrastructure (including virtual network setup, customer-managed keys, managed identities, and policies) as well as where you configure your Azure AI services. Azure AI hub resource access can allow you to modify the infrastructure, create new Azure AI hub resources, and create projects. Azure AI projects are a subset of the Azure AI hub resource that act as workspaces that allow you to build and deploy AI systems. Within a project you can develop flows, deploy models, and manage project assets. Project access lets you develop AI end-to-end while taking advantage of the infrastructure setup on the Azure AI hub resource.

-# Get started with the Azure AI CLI

-The Azure AI command-line interface (CLI) is a cross-platform command-line tool to connect to Azure AI services and execute control-plane and data-plane operations without having to write any code. The Azure AI CLI allows the execution of commands through a terminal using interactive command-line prompts or via script.

-You can easily use the Azure AI CLI to experiment with key Azure AI features and see how they work with your use cases. Within minutes, you can set up all the required Azure resources needed, and build a customized copilot using Azure OpenAI chat completions APIs and your own data. You can try it out interactively, or script larger processes to automate your own workflows and evaluations as part of your CI/CD system.

-## Prerequisites

-To use the Azure AI CLI, you need to install the prerequisites:

- * The Azure AI SDK, following the instructions [here](./sdk-install.md)

- * The Azure CLI (not the Azure `AI` CLI), following the instructions [here](/cli/azure/install-azure-cli)

- * The .NET SDK, following the instructions [here](/dotnet/core/install/) for your operating system and distro

-> [!NOTE]

-> If you launched VS Code from the Azure AI Studio, you don't need to install the prerequisites. See options without installing later in this article.

-## Run the Azure AI CLI without installing it

-You can install the Azure AI CLI locally as described previously, or run it using a preconfigured Docker container in VS Code.

-### Option 1: Using VS Code (web) in Azure AI Studio

-VS Code (web) in Azure AI Studio creates and runs the development container on a compute instance. To get started with this approach, follow the instructions in [Work with Azure AI projects in VS Code](develop-in-vscode.md).

-Our prebuilt development environments are based on a docker container that has the Azure AI SDK generative packages, the Azure AI CLI, the Prompt flow SDK, and other tools. It's configured to run VS Code remotely inside of the container. The docker container is similar to [this Dockerfile](https://github.com/Azure/aistudio-copilot-sample/blob/main/.devcontainer/Dockerfile), and is based on [Microsoft's Python 3.10 Development Container Image](https://mcr.microsoft.com/en-us/product/devcontainers/python/about).

-### OPTION 2: Visual Studio Code Dev Container

-You can run the Azure AI CLI in a Docker container using VS Code Dev Containers:

-1. Follow the [installation instructions](https://code.visualstudio.com/docs/devcontainers/containers#_installation) for VS Code Dev Containers.

-1. Clone the [aistudio-copilot-sample](https://github.com/Azure/aistudio-copilot-sample) repository and open it with VS Code:

- ```

- git clone https://github.com/azure/aistudio-copilot-sample

- code aistudio-copilot-sample

- ```

-1. Select the **Reopen in Dev Containers** button. If it doesn't appear, open the command palette (`Ctrl+Shift+P` on Windows and Linux, `Cmd+Shift+P` on Mac) and run the `Dev Containers: Reopen in Container` command.

-## Try the Azure AI CLI

-The AI CLI offers many capabilities, including an interactive chat experience, tools to work with prompt flows and search and speech services, and tools to manage AI services.

-If you plan to use the AI CLI as part of your development, we recommend you start by running `ai init`, which guides you through setting up your Azure resources and connections in your development environment.

-Try `ai help` to learn more about these capabilities.

-### ai init

-The `ai init` command allows interactive and non-interactive selection or creation of Azure AI hub resources. When an Azure AI hub resource is selected or created, the associated resource keys and region are retrieved and automatically stored in the local AI configuration datastore.

-You can initialize the Azure AI CLI by running the following command:

-```bash

-ai init

-```

-If you run the Azure AI CLI with VS Code (Web) coming from Azure AI Studio, your development environment will already be configured. The `ai init` command takes fewer steps: you confirm the existing project and attached resources.

-If your development environment hasn't already been configured with an existing project, or you select the **Initialize something else** option, there will be a few flows you can choose when running `ai init`: **Initialize a new AI project**, **Initialize an existing AI project**, or **Initialize standalone resources**.

-The following table describes the scenarios for each flow.

-| Scenario | Description |

-| | |

-| Initialize a new AI project | Choose if you don't have an existing AI project that you have been working with in the Azure AI Studio. The `ai init` command walks you through creating or attaching resources. |

-| Initialize an existing AI project | Choose if you have an existing AI project you want to work with. The `ai init` command checks your existing linked resources, and asks you to set anything that hasn't been set before. |

-| Initialize standalone resources| Choose if you're building a simple solution connected to a single AI service, or if you want to attach more resources to your development environment |

-Working with an AI project is recommended when using the Azure AI Studio and/or connecting to multiple AI services. Projects come with An Azure AI hub resource that houses related projects and shareable resources like compute and connections to services. Projects also allow you to connect code to cloud resources (storage and model deployments), save evaluation results, and host code behind online endpoints. You're prompted to create and/or attach Azure AI Services to your project.

-Initializing standalone resources is recommended when building simple solutions connected to a single AI service. You can also choose to initialize more standalone resources after initializing a project.

-The following resources can be initialized standalone, or attached to projects:

-#### Initializing a new AI project

-1. Run `ai init` and choose **Initialize new AI project**.

-1. Select your subscription. You might be prompted to sign in through an interactive flow.

-1. Select your Azure AI hub resource, or create a new one. An Azure AI hub resource can have multiple projects that can share resources.

-1. Select the name of your new project. There are some suggested names, or you can enter a custom one. Once you submit, the project might take a minute to create.

-1. Select the resources you want to attach to the project. You can skip resource types you don't want to attach.

-1. `ai init` checks you have the connections you need for the attached resources, and your development environment is configured with your new project.

-#### Initializing an existing AI project

-1. Enter `ai init` and choose "Initialize an existing AI project".

-1. Select your subscription. You might be prompted to sign in through an interactive flow.

-1. Select the project from the list.

-1. Select the resources you want to attach to the project. There should be a default selection based on what is already attached to the project. You can choose to create new resources to attach.

-1. `ai init` checks you have the connections you need for the attached resources, and your development environment is configured with the project.

-#### Initializing standalone resources

-1. Enter `ai init` and choose "Initialize standalone resources".

-1. Select the type of resource you want to initialize.

-1. Select your subscription. You might be prompted to sign in through an interactive flow.

-1. Choose the desired resources from the list(s). You can create new resources to attach inline.

-1. `ai init` checks you have the connections you need for the attached resources, and your development environment is configured with attached resources.

-## Project connections

-When working the Azure AI CLI, you want to use your project's connections. Connections are established to attached resources and allow you to integrate services with your project. You can have project-specific connections, or connections shared at the Azure AI hub resource level. For more information, see [Azure AI hub resources](../concepts/ai-resources.md) and [connections](../concepts/connections.md).

-When you run `ai init` your project connections get set in your development environment, allowing seamless integration with AI services. You can view these connections by running `ai service connection list`, and further manage these connections with `ai service connection` subcommands.

-Any updates you make to connections in the Azure AI CLI is reflected in [Azure AI Studio](https://ai.azure.com), and vice versa.

-## ai dev

-`ai dev` helps you configure the environment variables in your development environment.

-After running `ai init`, you can run the following command to set a `.env` file populated with environment variables you can reference in your code.

-```bash

-ai dev new .env

-```

-## ai service

-`ai service` helps you manage your connections to resources and services.

-## ai flow

-`ai flow` lets you work with prompt flows in an interactive way. You can create new flows, invoke and test existing flows, serve a flow locally to test an application experience, upload a local flow to the Azure AI Studio, or deploy a flow to an endpoint.

-The following steps help you test out each capability. They assume you have run `ai init`.

-1. Run `ai flow new --name mynewflow` to create a new flow folder based on a template for a chat flow.

-1. Open the `flow.dag.yaml` file that was created in the previous step.

- 1. Update the `deployment_name` to match the chat deployment attached to your project. You can run `ai config @chat.deployment` to get the correct name.

- 1. Update the connection field to be **Default_AzureOpenAI**. You can run `ai service connection list` to verify your connection names.

-1. `ai flow invoke --name mynewflow --input question=hello` - this runs the flow with provided input and return a response.

-1. `ai flow serve --name mynewflow` - this will locally serve the application and you can test interactively in a new window.

-1. `ai flow package --name mynewflow` - this packages the flow as a Dockerfile.

-1. `ai flow upload --name mynewflow` - this uploads the flow to the AI Studio, where you can continue working on it with the prompt flow UI.

-1. You can deploy an uploaded flow to an online endpoint for inferencing via the Azure AI Studio UI, see [Deploy a flow for real-time inference](./flow-deploy.md) for more details.

-

-### Project connections with flows

-As mentioned in step 2 above, your flow.dag.yaml should reference connection and deployment names matching those attached to your project.

-If you're working in your own development environment (including Codespaces), you might need to manually update these fields so that your flow runs connected to Azure resources.

-If you launched VS Code from the AI Studio, you are in an Azure-connected custom container experience, and you can work directly with flows stored in the `shared` folder. These flow files are the same underlying files prompt flow references in the Studio, so they should already be configured with your project connections and deployments. To learn more about the folder structure in the VS Code container experience, see [Work with Azure AI projects in VS Code](develop-in-vscode.md)

-## ai chat

-Once you have initialized resources and have a deployment, you can chat interactively or non-interactively with the AI language model using the `ai chat` command. The CLI has more examples of ways to use the `ai chat` capabilities, simply enter `ai chat` to try them. Once you have tested the chat capabilities, you can add in your own data.

-# [Terminal](#tab/terminal)

-Here's an example of interactive chat:

-```bash

-ai chat --interactive --system @prompt.txt

-```

-Here's an example of non-interactive chat:

-```bash

-ai chat --system @prompt.txt --user "Tell me about Azure AI Studio"

-```

-# [PowerShell](#tab/powershell)

-Here's an example of interactive chat:

-```powershell

-ai --% chat --interactive --system @prompt.txt

-```

-Here's an example of non-interactive chat:

-```powershell

-ai --% chat --system @prompt.txt --user "Tell me about Azure AI Studio"

-```

-> [!NOTE]

-> If you're using PowerShell, use the `--%` stop-parsing token to prevent the terminal from interpreting the `@` symbol as a special character.

-#### Chat with your data

-Once you have tested the basic chat capabilities, you can add your own data using an Azure AI Search vector index.

-1. Create a search index based on your data

-1. Interactively chat with an AI system grounded in your data

-1. Clear the index to prepare for other chat explorations

-```bash

-ai search index update --name <index_name> --files "*.md"

-ai chat --index-name <index_name> --interactive

-```

-When you use `search index update` to create or update an index (the first step above), `ai config` stores that index name. Run `ai config` in the CLI to see more usage details.

-If you want to set a different existing index for subsequent chats, use:

-```bash

-ai config --set search.index.name <index_name>

-```

-If you want to clear the set index name, use

-```bash

-ai config --clear search.index.name

-```

-## ai help

-The Azure AI CLI is interactive with extensive `help` commands. You can explore capabilities not covered in this document by running:

-```bash

-ai help

-```

-## Next steps

-Not available in AI CLI, but you can use [Azure Machine Learning CLI](../../machine-learning/how-to-managed-network.md#configure-a-managed-virtual-network-to-allow-internet-outbound). Use your Azure AI hub name as workspace name in Azure Machine Learning CLI.

-Not available in AI CLI, but you can use [Azure Machine Learning CLI](../../machine-learning/how-to-managed-network.md#configure-a-managed-virtual-network-to-allow-only-approved-outbound). Use your Azure AI hub name as workspace name in Azure Machine Learning CLI.

-Not available in AI CLI, but you can use [Azure Machine Learning CLI](../../machine-learning/how-to-managed-network.md#manage-outbound-rules). Use your Azure AI hub name as workspace name in Azure Machine Learning CLI.

-description: Learn how to configure a private link for Azure AI

-# How to configure a private link for Azure AI

-We have two network isolation aspects. One is the network isolation to access an Azure AI. Another is the network isolation of computing resources in your Azure AI and Azure AI projects such as Compute Instance, Serverless and Managed Online Endpoint. This document explains the former highlighted in the diagram. You can use private link to establish the private connection to your Azure AI and its default resources. This article is for Azure AI. For information on Azure AI Services, see the [Azure AI Services documentation](/azure/ai-services/cognitive-services-virtual-networks).

-You get several Azure AI default resources in your resource group. You need to configure following network isolation configurations.

-* You must have an existing virtual network to create the private endpoint in.

-After creating the Azure AI, use the [Azure networking CLI commands](/cli/azure/network/private-endpoint#az-network-private-endpoint-create) to create a private link endpoint for the Azure AI.

-# [Azure portal](#tab/azure-portal)

-1. From the [Azure portal](https://portal.azure.com), go to Azure AI Studio and choose __+ New Azure AI__.

-1. Choose network isolation mode in __Networking__ tab.

-1. Scroll down to __Workspace Inbound access__ and choose __+ Add__.

-1. Input required fields. When selecting the __Region__, select the same region as your virtual network.

-## Add a private endpoint to an Azure AI

-Use one of the following methods to add a private endpoint to an existing Azure AI:

-Use the [Azure networking CLI commands](/cli/azure/network/private-endpoint#az-network-private-endpoint-create) to create a private link endpoint for the Azure AI.

-# [Azure portal](#tab/azure-portal)

-1. From the [Azure portal](https://portal.azure.com), select your Azure AI.

-1. From the left side of the page, select __Networking__ and then select the __Private endpoint connections__ tab.

-1. When selecting the __Region__, select the same region as your virtual network.

-1. When selecting __Resource type__, use azuremlworkspace.

-1. Set the __Resource__ to your workspace name.

-Finally, select __Create__ to create the private endpoint.

-You can remove one or all private endpoints for an Azure AI. Removing a private endpoint removes the Azure AI from the VNet that the endpoint was associated with. Removing the private endpoint might prevent the Azure AI from accessing resources in that VNet, or resources in the VNet from accessing the workspace. For example, if the VNet doesn't allow access to or from the public internet.

-> Removing the private endpoints for a workspace __doesn't make it publicly accessible__. To make the workspace publicly accessible, use the steps in the [Enable public access](#enable-public-access) section.

-# [Azure portal](#tab/azure-portal)

-1. From the [Azure portal](https://portal.azure.com), select your Azure AI.

-1. From the left side of the page, select __Networking__ and then select the __Private endpoint connections__ tab.

-1. Select the endpoint to remove and then select __Remove__.

-In some situations, you might want to allow someone to connect to your secured Azure AI over a public endpoint, instead of through the VNet. Or you might want to remove the workspace from the VNet and re-enable public access.

-> Enabling public access doesn't remove any private endpoints that exist. All communications between components behind the VNet that the private endpoint(s) connect to are still secured. It enables public access only to the Azure AI, in addition to the private access through any private endpoints.

-# [Azure CLI](#tab/cli)

-Not available in AI CLI, but you can use [Azure Machine Learning CLI](../../machine-learning/how-to-configure-private-link.md#enable-public-access). Use your Azure AI name as workspace name in Azure Machine Learning CLI.

-1. From the [Azure portal](https://portal.azure.com), select your Azure AI.

-This is required if you make your storage account private. Our services need to read/write data in your private storage account using [Allow Azure services on the trusted services list to access this storage account](../../storage/common/storage-network-security.md#grant-access-to-trusted-azure-services) with below managed identity configurations. Enable system assigned managed identity of Azure AI Service and Azure AI Search, configure role-based access control for each managed identity.

-| `Storage File Data Privileged Contributor` | Azure AI project | Storage Account | Read/Write prompt flow data. | [Prompt flow doc](../../machine-learning/prompt-flow/how-to-secure-prompt-flow.md#secure-prompt-flow-with-workspace-managed-virtual-network) |

-| `Storage Blob Data Contributor` | Azure AI Search | Storage Account | Read blob and write knowledge store | [Search doc](../../search/search-howto-managed-identities-data-sources.md)|

-See [Azure Machine Learning custom dns doc](../../machine-learning/how-to-custom-dns.md#example-custom-dns-server-hosted-in-vnet) for the DNS forwarding configurations.

-If you need to configure custom dns server without dns forwarding, the following is the required A records.

-See [this documentation](../../machine-learning/how-to-custom-dns.md#find-the-ip-addresses) to check your private IP addresses for your A records. To check AI-PROJECT-GUID, go to Azure portal > Your Azure AI Project > JSON View > workspaceId.

-* Private Azure AI services and Azure AI Search aren't supported.

-* You might encounter problems trying to access the private endpoint for your Azure AI if you're using Mozilla Firefox. This problem might be related to DNS over HTTPS in Mozilla Firefox. We recommend using Microsoft Edge or Google Chrome.

-| [ai-resource.bicep](https://github.com/Azure/azure-quickstart-templates/blob/master/quickstarts/microsoft.machinelearningservices/aistudio-basics/modules/ai-resource.bicep) | Defines the Azure AI hub resource. |

-Note that disabling SSH prevents SSH access from the public internet. When a private virtual network is used, users can still SSH from within the virtual network.

-description: Learn how to deploy Llama 2 family of large language models with Azure AI Studio.

-# How to deploy Llama 2 family of large language models with Azure AI Studio

-In this article, you learn about the Llama 2 family of large language models (LLMs). You also learn how to use Azure AI Studio to deploy models from this set either as a service with pay-as you go billing or with hosted infrastructure in real-time endpoints.

-The Llama 2 family of LLMs is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. The model family also includes fine-tuned versions optimized for dialogue use cases with reinforcement learning from human feedback (RLHF), called Llama-2-chat.

-## Deploy Llama 2 models with pay-as-you-go

-Llama 2 models deployed as a service with pay-as-you-go are offered by Meta AI through Microsoft Azure Marketplace, and they might add more terms of use and pricing.

-The following models are available in Azure Marketplace for Llama 2 when deployed as a service with pay-as-you-go:

-If you need to deploy a different model, [deploy it to real-time endpoints](#deploy-llama-2-models-to-real-time-endpoints) instead.

- > For Llama 2 family models, the pay-as-you-go model deployment offering is only available with AI hubs created in **East US 2** and **West US 3** regions.

-1. If this is your first time deploying the model in the project, you have to subscribe your project for the particular offering (for example, Llama-2-70b) from Azure Marketplace. This step requires that your account has the Azure subscription permissions and resource group permissions listed in the prerequisites. Each project has its own subscription to the particular Azure Marketplace offering, which allows you to control and monitor spending. Select **Subscribe and Deploy**.

- > Subscribing a project to a particular Azure Marketplace offering (in this case, Llama-2-70b) requires that your account has **Contributor** or **Owner** access at the subscription level where the project is created. Alternatively, your user account can be assigned a custom role that has the Azure subscription permissions and resource group permissions listed in the [prerequisites](#prerequisites).

-To learn about billing for Llama models deployed with pay-as-you-go, see [Cost and quota considerations for Llama 2 models deployed as a service](#cost-and-quota-considerations-for-llama-2-models-deployed-as-a-service).

-### Consume Llama 2 models as a service

- - For completions models, such as `Llama-2-7b`, use the [`/v1/completions`](#completions-api) API.

- - For chat models, such as `Llama-2-7b-chat`, use the [`/v1/chat/completions`](#chat-api) API.

- For more information on using the APIs, see the [reference](#reference-for-llama-2-models-deployed-as-a-service) section.

-### Reference for Llama 2 models deployed as a service

- "max_tokens": 512,

-## Deploy Llama 2 models to real-time endpoints

-Apart from deploying with the pay-as-you-go managed service, you can also deploy Llama 2 models to real-time endpoints in AI Studio. When deployed to real-time endpoints, you can select all the details about the infrastructure running the model, including the virtual machines to use and the number of instances to handle the load you're expecting. Models deployed to real-time endpoints consume quota from your subscription. All the models in the Llama family can be deployed to real-time endpoints.

-### Create a new deployment

-# [Studio](#tab/azure-studio)

-Follow these steps to deploy a model such as `Llama-2-7b-chat` to a real-time endpoint in [Azure AI Studio](https://ai.azure.com).

-# [Python SDK](#tab/python)

-Follow these steps to deploy an open model such as `Llama-2-7b-chat` to a real-time endpoint, using the Azure AI Generative SDK.

- deployment_name = "my-llam27bchat-deployment"

-### Consume Llama 2 models deployed to real-time endpoints

-For reference about how to invoke Llama 2 models deployed to real-time endpoints, see the model's card in the Azure AI Studio [model catalog](../how-to/model-catalog.md). Each model's card has an overview page that includes a description of the model, samples for code-based inferencing, fine-tuning, and model evaluation.

-### Cost and quota considerations for Llama 2 models deployed as a service

-### Cost and quota considerations for Llama 2 models deployed as real-time endpoints

-Azure AI Studio supports developing in VS Code - Web and Desktop. In each scenario, your VS Code instance is remotely connected to a prebuilt custom container running on a virtual machine, also known as a compute instance. To work in your local environment instead, or to learn more, follow the steps in [Install the Azure AI SDK](sdk-install.md) and [Install the Azure AI CLI](cli-install.md).

-python --version # ensure you've >=3.8

-## Create an index

-1. Choose your **Source data**. You can choose source data from a list of your recent data sources, a storage URL on the cloud or even upload files and folders from the local machine. You can also add a connection to another data source such as Azure Blob Storage.

- 1. The search type defaults to **Hybrid + Semantic**, which is a combination of keyword search, vector search and semantic search to give the best possible search results.

- 1. For the hybrid option to work, you need an embedding model. Choose the Azure OpenAI resource, which has the embedding model

-

-1. Use the prefilled name or type your own name for New Vector index name

-

- > [!NOTE]

- > If you see a **DeploymentNotFound** error, you need to assign more permissions. See [mitigate DeploymentNotFound error](#mitigate-deploymentnotfound-error) for more details.

-### Mitigate DeploymentNotFound error

-When you try to create a vector index, you might see the following error at the **Review + Finish** step:

-**Failed to create vector index. DeploymentNotFound: A valid deployment for the model=text-embedding-ada-002 was not found in the workspace connection=Default_AzureOpenAI provided.**

-This can happen if you are trying to create an index using an **Owner**, **Contributor**, or **Azure AI Developer** role at the project level. To mitigate this error, you might need to assign more permissions using either of the following methods.

-> [!NOTE]

-> You need to be assigned the **Owner** role of the resource group or higher scope (like Subscription) to perform the operation in the next steps. This is because only the Owner role can assign roles to others. See details [here](/azure/role-based-access-control/built-in-roles).

-#### Method 1: Assign more permissions to the user on the Azure AI hub resource

-If the Azure AI hub resource the project uses was created through Azure AI Studio:

-1. Sign in to [Azure AI Studio](https://aka.ms/azureaistudio) and select your project via **Build** > **Projects**.

-1. Select **AI project settings** from the collapsible left menu.

-1. From the **Resource Configuration** section, select the link for your resource group name that takes you to the Azure portal.

-1. In the Azure portal under **Overview** > **Resources** select the Azure AI service type. It's named similar to "YourAzureAIResourceName-aiservices."

- :::image type="content" source="../media/roles-access/resource-group-azure-ai-service.png" alt-text="Screenshot of Azure AI service in a resource group." lightbox="../media/roles-access/resource-group-azure-ai-service.png":::

-1. Select **Access control (IAM)** > **+ Add** to add a role assignment.

-1. Add the **Cognitive Services OpenAI User** role to the user who wants to make an index. `Cognitive Services OpenAI Contributor` and `Cognitive Services Contributor` also work, but they assign more permissions than needed for creating an index in Azure AI Studio.

-> [!NOTE]

-> You can also opt to assign more permissions [on the resource group](#method-2-assign-more-permissions-on-the-resource-group). However, that method assigns more permissions than needed to mitigate the **DeploymentNotFound** error.

-#### Method 2: Assign more permissions on the resource group

-If the Azure AI hub resource the project uses was created through Azure portal:

-1. Sign in to [Azure AI Studio](https://aka.ms/azureaistudio) and select your project via **Build** > **Projects**.

-1. Select **AI project settings** from the collapsible left menu.

-1. From the **Resource Configuration** section, select the link for your resource group name that takes you to the Azure portal.

-1. Select **Access control (IAM)** > **+ Add** to add a role assignment.

-1. Add the **Cognitive Services OpenAI User** role to the user who wants to make an index. `Cognitive Services OpenAI Contributor` and `Cognitive Services Contributor` also work, but they assign more permissions than needed for creating an index in Azure AI Studio.

-## Remarks

-description: This article introduces the Prompt tool for flows in Azure AI Studio.

-The prompt flow *Prompt* tool offers a collection of textual templates that serve as a starting point for creating prompts. These templates, based on the [Jinja](https://jinja.palletsprojects.com/en/3.1.x/) template engine, facilitate the definition of prompts. The tool proves useful when prompt tuning is required prior to feeding the prompts into the large language model (LLM) in prompt flow.

-Prepare a prompt. The [LLM tool](llm-tool.md) and Prompt tool both support [Jinja](https://jinja.palletsprojects.com/en/3.1.x/) templates.

-In this example, the prompt incorporates Jinja templating syntax to dynamically generate the welcome message and personalize it based on the user's name. It also presents a menu of options for the user to choose from. Depending on whether the user_name variable is provided, it either addresses the user by name or uses a generic greeting.

-For more information and best practices, see [prompt engineering techniques](../../../ai-services/openai/concepts/advanced-prompt-engineering.md).

-The list of inputs will change based on the arguments of the tool function, after you save the code. Adding type to arguments and return values help the tool show the types properly.

-| Code | string | Python code snippet | Yes |

-| Inputs | - | List of tool function parameters and its assignments | - |

-The output is the `return` value of the python tool function. For example, consider the following python tool function:

-If the input message is "world", the output is `hello world`.

-| Connection | param: CustomConnection | Connection type will be handled specially |

-Parameters with `Connection` type annotation will be treated as connection inputs, which means:

-> [!Note]

-> `Union[...]` type annotation is only supported for connection type, for example, `param: Union[CustomConnection, OpenAIConnection]`.

-## Consume custom connection in the Python tool

-If you're developing a python tool that requires calling external services with authentication, you can use the custom connection in prompt flow. It allows you to securely store the access key and then retrieve it in your python code.

-Create a custom connection that stores all your LLM API KEY or other required credentials.

-1. Go to **AI project settings**, then select **New Connection**.

-1. Select **Custom** service. You can define your connection name, and you can add multiple *Key-value pairs* to store your credentials and keys by selecting **Add key-value pairs**.

- > Make sure at least one key-value pair is set as secret, otherwise the connection will not be created successfully. You can set one Key-Value pair as secret by **is secret** checked, which will be encrypted and stored in your key value.

-### Remarks about adding your data

-Although it's beyond the scope of this tutorial, to understand more about how the model uses your data, you can export the playground setup to prompt flow.

-Following through from there you can see the graphical representation of how the model uses your data to construct the response. For more information about prompt flow, see [prompt flow](../how-to/prompt-flow.md).

- > Evaluation with AI-assisted metrics needs to call another GPT model to do the calculation. For best performance, use a GPT-4 or gpt-35-turbo-16k model. If you didn't previously deploy a GPT-4 or gpt-35-turbo-16k model, you can deploy another model by following the steps in [Deploy a chat model](#deploy-a-chat-model). Then return to this step and select the model you deployed.

- > The evaluation process may take up lots of tokens, so it's recommended to use a model which can support >=16k tokens.

-1. Install the [Azure AI CLI](../how-to/cli-install.md). The Azure AI CLI is a command-line interface for managing Azure AI resources. It's used to configure resources needed for your copilot.

-In this section, you use the [Azure AI CLI](../how-to/cli-install.md) to configure resources needed for your copilot:

-You use the following evaluation dataset, which contains a bunch of example questions and answers. The evaluation dataset is located at `src/copilot_aisdk/system-message.jinja2` in the copilot sample repository.

- kubectl apply -f https://raw.githubusercontent.com/Azure/kaito/main/examples/kaito_workspace_falcon_7b-instruct.yaml

- az aks update --resource-group myResourceGroup --name myAKSCluster -api-server-authorized-ip-ranges 73.140.245.0/24

-You can convert existing public/private AKS clusters to API Server VNet Integration clusters by supplying an API server subnet that meets the requirements listed earlier. These requirements include: in the same VNet as the cluster nodes, permissions granted for the AKS cluster identity, and size of at least */28*. Converting your cluster is a one-way migration. Clusters can't have API Server VNet Integration disabled after it's been enabled.

-description: Learn how to create a static or dynamic persistent volume with Azure Blob storage for use with multiple concurrent pods in Azure Kubernetes Service (AKS)

-### Storage class parameters for dynamic PersistentVolumes

-The following table includes parameters you can use to define a custom storage class for your PersistentVolumeClaim.

-The default storage classes suit the most common scenarios, but not all. For some cases, you might want to have your own storage class customized with your own parameters. To demonstrate, two examples are shown. One based on using the NFS protocol, and the other using blobfuse.

-### Static provisioning parameters for PersistentVolume

-The following table includes parameters you can use to define a PersistentVolume.

- > While the [Kubernetes API](https://github.com/kubernetes/kubernetes/blob/release-1.26/pkg/apis/core/types.go#L303-L306) **capacity** attribute is mandatory, this value isn't used by the Azure Blob storage CSI driver because you can flexibly write data until you reach your storage account's capacity limit. The value of the `capacity` attribute is used only for size matching between *PersistentVolumes* and *PersistenVolumeClaims*. We recommend using a fictitious high value. The pod sees a mounted volume with a fictitious size of 5 Petabytes.

-* You need an Azure [storage account][azure-storage-account].

-|DiskIOPSReadWrite | [UltraSSD disk][ultra-ssd-disks] IOPS Capability (minimum: 2 IOPS/GiB) | 100~160000 | No | `500`|

-|DiskMBpsReadWrite | [UltraSSD disk][ultra-ssd-disks] Throughput Capability(minimum: 0.032/GiB) | 1~2000 | No | `100`|

-It's not supported to reduce the size of a PVC (to prevent data loss). You can edit an existing storage class using the `kubectl edit sc` command, or you can create your own custom storage class. For example, if you want to use a disk of size 4 TiB, you must create a storage class that defines `cachingmode: None` because [disk caching isn't supported for disks 4 TiB and larger][disk-host-cache-setting]. For more information about storage classes and creating your own storage class, see [Storage options for applications in AKS][storage-class-concepts].

-This section provides guidance for cluster administrators who want to create one or more persistent volumes that include details of Azure Disks storage for use by a workload.

-### Static provisioning parameters for PersistentVolume

-2. Create a disk using the [`az disk create`][az-disk-create] command. Specify the node resource group name and a name for the disk resource, such as *myAKSDisk*. The following example creates a *20*GiB disk, and outputs the ID of the disk after it's created. If you need to create a disk for use with Windows Server containers, add the `--os-type windows` parameter to correctly format the disk.

-### Pod anti-affinity

-> Use pod anti-affinity to ensure that pods are spread across nodes for node-down scenarios.

-You can use the `nodeSelector` field in your pod specification to specify the node labels you want the target node to have. Kubernetes only schedules the pod onto nodes that have the specified labels. Anti-affinity expands the types of constraints you can define and gives you more control over the selection logic. Anti-affinity allows you to constrain pods against labels on other pods.

-The following example pod definition file shows how to use pod anti-affinity to ensure that pods are spread across nodes:

-apiVersion: apps/v1

-kind: Deployment

- name: multi-zone-deployment

- labels:

- app: myapp

- replicas: 3

- selector:

- matchLabels:

- app: myapp

- template:

- metadata:

- labels:

- app: myapp

- spec:

- containers:

- - name: myapp-container

- image: nginx

- ports:

- - containerPort: 80

- affinity:

- requiredDuringSchedulingIgnoredDuringExecution:

- - labelSelector:

- matchExpressions:

- - key: app

- operator: In

- values:

- - myapp

- topologyKey: topology.kubernetes.io/zone

-For more information, see [Affinity and anti-affinity in Kubernetes](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#affinity-and-anti-affinity).

-> [!TIP]

-> Use pod anti-affinity across availability zones to ensure that pods are spread across availability zones for zone-down scenarios.

->

-> You can think of availability zones as backups for your application. If one zone goes down, your application can continue to run in another zone. You use affinity and anti-affinity rules to schedule specific pods on specific nodes. For example, let's say you have a memory/CPU-intensive pod, you might want to schedule it on a larger VM SKU to give the pod the capacity it needs to run.

->

-> When you deploy your application across multiple availability zones, you can use pod anti-affinity to ensure that pods are spread across availability zones. This practice helps ensure that your application remains available in the event of a zone-down scenario.

->

-> For more information, see [Best practices for multiple zones](https://kubernetes.io/docs/setup/best-practices/multiple-zones/) and [Overview of availability zones for AKS clusters](./availability-zones.md#overview-of-availability-zones-for-aks-clusters).

-AKS doesn't expose control plane and API server metrics via Prometheus or through platform metrics. However, you can analyze API server traffic and client behavior through Kube Audit logs. For more information, see [Troubleshoot the Kubernetes control plane](/troubleshoot/azure/azure-kubernetes/troubleshoot-apiserver-etcd).

-* AKS supports scaling up to 5,000 nodes by default for all Standard Tier / LTS clusters. AKS scales your cluster's control plane at runtime based on cluster size and API server resource utilization. If you cannot scale up to the supported limit, enable [control plane metrics (Preview)](./monitor-control-plane-metrics.md) with the [Azure Monitor managed service for Prometheus](../azure-monitor/essentials/prometheus-metrics-overview.md) to monitor the control plane. To help troubleshoot scaling performance or reliability issues, see the following resources:

-description: Learn how to configure a cluster in Azure Kubernetes Service (AKS)

-# Configure an AKS cluster

-As part of creating an AKS cluster, you may need to customize your cluster configuration to suit your needs. This article introduces a few options for customizing your AKS cluster.

-## OS configuration

-AKS supports Ubuntu 22.04 and Azure Linux 2.0 as the node operating system (OS) for clusters with Kubernetes 1.25 and higher. Ubuntu 18.04 can also be specified at node pool creation for Kubernetes versions 1.24 and below.

-AKS supports Windows Server 2022 as the default operating system (OS) for Windows node pools in clusters with Kubernetes 1.25 and higher. Windows Server 2019 can also be specified at node pool creation for Kubernetes versions 1.32 and below. Windows Server 2019 is being retired after Kubernetes version 1.32 reaches end of life (EOL) and isn't supported in future releases. For more information about this retirement, see the [AKS release notes][aks-release-notes].

-## Container runtime configuration

-A container runtime is software that executes containers and manages container images on a node. The runtime helps abstract away sys-calls or operating system (OS) specific functionality to run containers on Linux or Windows. For Linux node pools, `containerd` is used on Kubernetes version 1.19 and higher. For Windows Server 2019 and 2022 node pools, `containerd` is generally available and is the only runtime option on Kubernetes version 1.23 and higher. As of May 2023, Docker is retired and no longer supported. For more information about this retirement, see the [AKS release notes][aks-release-notes].

-[`Containerd`](https://containerd.io/) is an [OCI](https://opencontainers.org/) (Open Container Initiative) compliant core container runtime that provides the minimum set of required functionality to execute containers and manage images on a node. `Containerd` was [donated](https://www.cncf.io/announcement/2017/03/29/containerd-joins-cloud-native-computing-foundation/) to the Cloud Native Compute Foundation (CNCF) in March of 2017. AKS uses the current Moby (upstream Docker) version, which is built on top of `containerd`.

-With a `containerd`-based node and node pools, instead of talking to the `dockershim`, the kubelet talks directly to `containerd` using the CRI (container runtime interface) plugin, removing extra hops in the data flow when compared to the Docker CRI implementation. As such, you see better pod startup latency and less resource (CPU and memory) usage.

-By using `containerd` for AKS nodes, pod startup latency improves and node resource consumption by the container runtime decreases. These improvements through this new architecture enable kubelet communicating directly to `containerd` through the CRI plugin. While in a Moby/docker architecture, kubelet communicates to the `dockershim` and docker engine before reaching `containerd`, therefore having extra hops in the data flow. For more details on the origin of the `dockershim` and its deprecation, see the [Dockershim removal FAQ][kubernetes-dockershim-faq].

-

-`Containerd` works on every GA version of Kubernetes in AKS, and in every newer Kubernetes version above v1.19, and supports all Kubernetes and AKS features.

-> [!IMPORTANT]

-> Clusters with Linux node pools created on Kubernetes v1.19 or greater default to `containerd` for its container runtime. Clusters with node pools on a earlier supported Kubernetes versions receive Docker for their container runtime. Linux node pools will be updated to `containerd` once the node pool Kubernetes version is updated to a version that supports `containerd`.

->

-> `containerd` with Windows Server 2019 and 2022 node pools is generally available, and is the only container runtime option in Kubernetes 1.23 and higher. You can continue using Docker node pools and clusters on versions earlier than 1.23, but Docker is no longer supported as of May 2023. For more information, see [Add a Windows Server node pool with `containerd`][aks-add-np-containerd].

->

-> We highly recommend testing your workloads on AKS node pools with `containerd` before using clusters with a Kubernetes version that supports `containerd` for your node pools.

-### `containerd` limitations/differences

-* For `containerd`, we recommend using [`crictl`](https://kubernetes.io/docs/tasks/debug-application-cluster/crictl) as a replacement CLI instead of the Docker CLI for **troubleshooting** pods, containers, and container images on Kubernetes nodes. For more information on `crictl`, see [General usage][general-usage] and [Client configuration options][client-config-options].

- * `Containerd` doesn't provide the complete functionality of the docker CLI. It's available for troubleshooting only.

- * `crictl` offers a more Kubernetes-friendly view of containers, with concepts like pods, etc. being present.

-* `Containerd` sets up logging using the standardized `cri` logging format (which is different from what you currently get from docker's json driver). Your logging solution needs to support the `cri` logging format (like [Azure Monitor for Containers](../azure-monitor/containers/container-insights-enable-new-cluster.md))

-* You can no longer access the docker engine, `/var/run/docker.sock`, or use Docker-in-Docker (DinD).

- * If you currently extract application logs or monitoring data from Docker engine, use [Container insights](../azure-monitor/containers/container-insights-enable-new-cluster.md) instead. AKS doesn't support running any out of band commands on the agent nodes that could cause instability.

- * Building images and directly using the Docker engine using the methods mentioned earlier aren't recommended. Kubernetes isn't fully aware of those consumed resources, and those methods present numerous issues as described [here](https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/) and [here](https://securityboulevard.com/2018/05/escaping-the-whale-things-you-probably-shouldnt-do-with-docker-part-1/).

-* Building images - You can continue to use your current Docker build workflow as normal, unless you're building images inside your AKS cluster. In this case, consider switching to the recommended approach for building images using [ACR Tasks](../container-registry/container-registry-quickstart-task-cli.md), or a more secure in-cluster option like [Docker Buildx](https://github.com/docker/buildx).

-## Generation 2 virtual machines

-Azure supports [Generation 2 (Gen2) virtual machines (VMs)](../virtual-machines/generation-2.md). Generation 2 VMs support key features not supported in generation 1 VMs (Gen1). These features include increased memory, Intel Software Guard Extensions (Intel SGX), and virtualized persistent memory (vPMEM).

-Generation 2 VMs use the new UEFI-based boot architecture rather than the BIOS-based architecture used by generation 1 VMs. Only specific SKUs and sizes support Gen2 VMs. Check the [list of supported sizes](../virtual-machines/generation-2.md#generation-2-vm-sizes), to see if your SKU supports or requires Gen2.

-Additionally, not all VM images support Gen2 VMs. On AKS, Gen2 VMs use [AKS Ubuntu 22.04 or 18.04 image](#os-configuration) or [AKS Windows Server 2022 image](#os-configuration). These images support all Gen2 SKUs and sizes.

-Gen2 VMs are supported on Linux. Gen2 VMs on Windows are supported for WS2022 only.

-### Generation 2 virtual machines on Windows

-#### Limitations

-* Generation 2 VMs are supported on Windows for WS2022 only.

-* Generation 2 VMs are default for Windows clusters greater than or equal to Kubernetes 1.25.

-* If you select a vm size which supports both Gen 1 and Gen 2, the default for windows node pools will be Gen 1. To specify Gen 2, use custom header `UseWindowsGen2VM=true`.

-#### Add a Windows node pool with a generation 2 VM

-* Add a node pool with generation 2 VMs on Windows using the [`az aks nodepool add`][az-aks-nodepool-add] command.

- ```azurecli

- az aks nodepool add --resource-group myResourceGroup --cluster-name myAKSCluster --name gen2np --node-vm-size Standard_D32_v4 --os-type Windows --aks-custom-headers UseWindowsGen2VM=true

- ```

-The above example will create a WS2022 node pool with a Gen 2 VM. If you're using a vm size which only supports Gen 2, you do not need to add the custom header. If you're using a kubernetes version where Windows Server 2022 is not default, you need to specify `--os-sku`.

-* Check whether you're using generation 1 or generation 2 using the [`az aks nodepool show`][az-aks-nodepool-show] command, and check that the `nodeImageVersion` contains `gen2`.

- ```azurecli

- az aks nodepool show

- ```

-* Check available generation 2 VM sizes using the [`az vm list`][az-vm-list] command.

- ```azurecli

- az vm list -skus -l $region

- ```

-For more information, see [Support for generation 2 VMs on Azure](../virtual-machines/generation-2.md).

-## Default OS disk sizing

-When you create a new cluster or add a new node pool to an existing cluster, the number for vCPUs by default determines the OS disk size. The number of vCPUs is based on the VM SKU, and in the following table we list the default values:

-|VM SKU Cores (vCPUs)| Default OS Disk Tier | Provisioned IOPS | Provisioned Throughput (Mbps) |

-|--|--|--|--|

-| 1 - 7 | P10/128G | 500 | 100 |

-| 8 - 15 | P15/256G | 1100 | 125 |

-| 16 - 63 | P20/512G | 2300 | 150 |

-| 64+ | P30/1024G | 5000 | 200 |

-> [!IMPORTANT]

-> Default OS disk sizing is only used on new clusters or node pools when ephemeral OS disks are not supported and a default OS disk size isn't specified. The default OS disk size may impact the performance or cost of your cluster, and you cannot change the OS disk size after cluster or node pool creation. This default disk sizing affects clusters or node pools created on July 2022 or later.

-## Use Ephemeral OS on new clusters

-Configure the cluster to use ephemeral OS disks when the cluster is created. Use the `--node-osdisk-type` argument to set Ephemeral OS as the OS disk type for the new cluster.

-```azurecli

-az aks create --name myAKSCluster --resource-group myResourceGroup -s Standard_DS3_v2 --node-osdisk-type Ephemeral

-```

-If you want to create a regular cluster using network-attached OS disks, you can do so by specifying the `--node-osdisk-type=Managed` argument. You can also choose to add other ephemeral OS node pools, which we cover in the following section.

-## Use Ephemeral OS on existing clusters

-Configure a new node pool to use Ephemeral OS disks. Use the `--node-osdisk-type` argument to set as the OS disk type as the OS disk type for that node pool.

-```azurecli

-az aks nodepool add --name ephemeral --cluster-name myAKSCluster --resource-group myResourceGroup -s Standard_DS3_v2 --node-osdisk-type Ephemeral

-```

-> [!IMPORTANT]

-> With ephemeral OS you can deploy VM and instance images up to the size of the VM cache. In the AKS case, the default node OS disk configuration uses 128 GB, which means that you need a VM size that has a cache larger than 128 GB. The default Standard_DS2_v2 has a cache size of 86 GB, which isn't large enough. The Standard_DS3_v2 has a cache size of 172 GB, which is large enough. You can also reduce the default size of the OS disk by using `--node-osdisk-size`. The minimum size for AKS images is 30 GB.

-If you want to create node pools with network-attached OS disks, you can do so by specifying `--node-osdisk-type Managed`.

-## Azure Linux container host for AKS

-You can deploy the Azure Linux container host for through Azure CLI or ARM templates.

-### Prerequisites

-1. You need the Azure CLI version 2.44.1 or later installed and configured. Run `az --version` to find the version currently installed. If you need to install or upgrade, see [Install Azure CLI][azure-cli-install].

-1. If you don't already have kubectl installed, install it through Azure CLI using `az aks install-cli` or follow the [upstream instructions](https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/).

-### Deploy an Azure Linux AKS cluster with Azure CLI

-Use the following example commands to create an Azure Linux cluster.

-```azurecli

-az group create --name AzureLinuxTest --location eastus

-az aks create --name testAzureLinuxCluster --resource-group AzureLinuxTest --os-sku AzureLinux --generate-ssh-keys

-az aks get-credentials --resource-group AzureLinuxTest --name testAzureLinuxCluster

-kubectl get pods --all-namespaces

-```

-### Deploy an Azure Linux AKS cluster with an ARM template

-To add Azure Linux to an existing ARM template, you need to make the following changes:

-The following deployment uses the ARM template `azurelinuxaksarm.json`.

-az aks get-credentials --resource-group AzureLinuxTest --name testAzureLinuxCluster

-kubectl get pods --all-namespaces

-```

-### Deploy an Azure Linux AKS cluster with Terraform

-To deploy an Azure Linux cluster with Terraform, you first need to set your `azurerm` provider to version 2.76 or higher.

-```

-required_providers {

- azurerm = {

- source = "hashicorp/azurerm"

- version = "~> 2.76"

- }

-}

-```

-Once you've updated your `azurerm` provider, you can specify the AzureLinux `os_sku` in `default_node_pool`.

-```

-default_node_pool {

- name = "default"

- node_count = 2

- vm_size = "Standard_D2_v2"

- os_sku = "AzureLinux"

-}

-```

-Similarly, you can specify the AzureLinux `os_sku` in [`azurerm_kubernetes_cluster_node_pool`][azurerm-azurelinux].

-## Custom resource group name

-When you deploy an Azure Kubernetes Service cluster in Azure, it also creates a second resource group for the worker nodes. By default, AKS names the node resource group `MC_resourcegroupname_clustername_location`, but you can specify a custom name.

-To specify a custom resource group name, install the `aks-preview` Azure CLI extension version 0.3.2 or later. When using the Azure CLI, include the `--node-resource-group` parameter with the `az aks create` command to specify a custom name for the resource group. To deploy an AKS cluster with an Azure Resource Manager template, you can define the resource group name by using the `nodeResourceGroup` property.

-```azurecli

-az aks create --name myAKSCluster --resource-group myResourceGroup --node-resource-group myNodeResourceGroup

-```

-The Azure resource provider in your subscription automatically creates the secondary resource group. You can only specify the custom resource group name during cluster creation.

-As you work with the node resource group, keep in mind that you can't:

-## Node Restriction (Preview)

-The [Node Restriction](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#noderestriction) admission controller limits the Node and Pod objects a kubelet can modify. Node Restriction is on by default in AKS 1.24+ clusters. If you're using an older version, use the following commands to create a cluster with Node Restriction, or update an existing cluster to add Node Restriction.

-### Before you begin

-You must have the following resource installed:

-* The Azure CLI

-* The `aks-preview` extension version 0.5.95 or later

-#### Install the aks-preview CLI extension

-```azurecli-interactive

-# Install the aks-preview extension

-az extension add --name aks-preview

-# Update the extension to make sure you have the latest version installed

-az extension update --name aks-preview

-```

-### Create an AKS cluster with Node Restriction

-To create a cluster using Node Restriction.

-```azurecli-interactive

-az aks create -n aks -g myResourceGroup --enable-node-restriction

-```

-### Update an AKS cluster with Node Restriction

-To update a cluster to use Node Restriction.

-```azurecli-interactive

-az aks update -n aks -g myResourceGroup --enable-node-restriction

-```

-### Remove Node Restriction from an AKS cluster

-To remove Node Restriction from a cluster.

-```azurecli-interactive

-az aks update -n aks -g myResourceGroup --disable-node-restriction

-```

-## Fully managed resource group (Preview)

-AKS deploys infrastructure into your subscription for connecting to and running your applications. Changes made directly to resources in the [node resource group][whatis-nrg] can affect cluster operations or cause issues later. For example, scaling, storage, or network configuration should be through the Kubernetes API, and not directly on these resources.

-To prevent changes from being made to the Node Resource Group, you can apply a deny assignment and block users from modifying resources created as part of the AKS cluster.

-### Before you begin

-You must have the following resources installed:

-* The Azure CLI version 2.44.0 or later. Run `az --version` to find the current version, and if you need to install or upgrade, see [Install Azure CLI][azure-cli-install].

-* The `aks-preview` extension version 0.5.126 or later

-#### Install the aks-preview CLI extension

-```azurecli-interactive

-# Install the aks-preview extension

-az extension add --name aks-preview

-# Update the extension to make sure you have the latest version installed

-az extension update --name aks-preview

-```

-#### Register the 'NRGLockdownPreview' feature flag

-Register the `NRGLockdownPreview` feature flag by using the [az feature register][az-feature-register] command, as shown in the following example:

-```azurecli-interactive

-az feature register --namespace "Microsoft.ContainerService" --name "NRGLockdownPreview"

-```

-It takes a few minutes for the status to show *Registered*. Verify the registration status by using the [az feature show][az-feature-show] command:

-```azurecli-interactive

-az feature show --namespace "Microsoft.ContainerService" --name "NRGLockdownPreview"

-```

-When the status reflects *Registered*, refresh the registration of the *Microsoft.ContainerService* resource provider by using the [az provider register][az-provider-register] command:

-```azurecli-interactive

-az provider register --namespace Microsoft.ContainerService

-```

-### Create an AKS cluster with node resource group lockdown

-To create a cluster using node resource group lockdown, set the `--nrg-lockdown-restriction-level` to **ReadOnly**. This configuration allows you to view the resources, but not modify them.

-```azurecli-interactive

-az aks create -n aksTest -g aksTest --nrg-lockdown-restriction-level ReadOnly

-```

-### Update an existing cluster with node resource group lockdown

-```azurecli-interactive

-az aks update -n aksTest -g aksTest --nrg-lockdown-restriction-level ReadOnly

-```

-### Remove node resource group lockdown from a cluster

-```azurecli-interactive

-az aks update -n aksTest -g aksTest --nrg-lockdown-restriction-level Unrestricted

-```

-# Core Kubernetes concepts for Azure Kubernetes Service

-Application development continues to move toward a container-based approach, increasing our need to orchestrate and manage resources. As the leading platform, Kubernetes provides reliable scheduling of fault-tolerant application workloads. Azure Kubernetes Service (AKS), a managed Kubernetes offering, further simplifies container-based application deployment and management.

-This article introduces core concepts:

-* Kubernetes infrastructure components:

- * *control plane*

-Kubernetes is a rapidly evolving platform that manages container-based applications and their associated networking and storage components. Kubernetes focuses on the application workloads, not the underlying infrastructure components. Kubernetes provides a declarative approach to deployments, backed by a robust set of APIs for management operations.

-You can build and run modern, portable, microservices-based applications, using Kubernetes to orchestrate and manage the availability of the application components. Kubernetes supports both stateless and stateful applications as teams progress through the adoption of microservices-based applications.

-AKS provides a managed Kubernetes service that reduces the complexity of deployment and core management tasks, like upgrade coordination. The Azure platform manages the AKS control plane, and you only pay for the AKS nodes that run your applications.

-When you create an AKS cluster, a control plane is automatically created and configured. This control plane is provided at no cost as a managed Azure resource abstracted from the user. You only pay for the nodes attached to the AKS cluster. The control plane and its resources reside only on the region where you created the cluster.

-| *kube-apiserver* | The API server is how the underlying Kubernetes APIs are exposed. This component provides the interaction for management tools, such as `kubectl` or the Kubernetes dashboard. |

-| *etcd* | To maintain the state of your Kubernetes cluster and configuration, the highly available *etcd* is a key value store within Kubernetes. |

-| *kube-scheduler* | When you create or scale applications, the Scheduler determines what nodes can run the workload and starts them. |

-| *kube-controller-manager* | The Controller Manager oversees a number of smaller controllers that perform actions such as replicating pods and handling node operations. |

-AKS provides a single-tenant control plane, with a dedicated API server, scheduler, etc. You define the number and size of the nodes, and the Azure platform configures the secure communication between the control plane and nodes. Interaction with the control plane occurs through Kubernetes APIs, such as `kubectl` or the Kubernetes dashboard.

-While you don't need to configure components (like a highly available *etcd* store) with this managed control plane, you can't access the control plane directly. Kubernetes control plane and node upgrades are orchestrated through the Azure CLI or Azure portal. To troubleshoot possible issues, you can review the control plane logs through Azure Monitor logs.

-To configure or directly access a control plane, deploy a self-managed Kubernetes cluster using [Cluster API Provider Azure][cluster-api-provider-azure].

-For associated best practices, see [Best practices for cluster security and upgrades in AKS][operator-best-practices-cluster-security].

-For AKS cost management information, see [AKS cost basics](/azure/architecture/aws-professional/eks-to-aks/cost-management#aks-cost-basics) and [Pricing for AKS](https://azure.microsoft.com/pricing/details/kubernetes-service/#pricing).

-## Nodes and node pools

-To run your applications and supporting services, you need a Kubernetes *node*. An AKS cluster has at least one node, an Azure virtual machine (VM) that runs the Kubernetes node components and container runtime.

-| *kube-proxy* | Handles virtual networking on each node. The proxy routes network traffic and manages IP addressing for services and pods. |

-| *container runtime* | Allows containerized applications to run and interact with additional resources, such as the virtual network or storage. AKS clusters using Kubernetes version 1.19+ for Linux node pools use `containerd` as their container runtime. Beginning in Kubernetes version 1.20 for Windows node pools, `containerd` can be used in preview for the container runtime, but Docker is still the default container runtime. AKS clusters using prior versions of Kubernetes for node pools use Docker as their container runtime. |

-The Azure VM size for your nodes defines CPUs, memory, size, and the storage type available (such as high-performance SSD or regular HDD). Plan the node size around whether your applications may require large amounts of CPU and memory or high-performance storage. Scale out the number of nodes in your AKS cluster to meet demand. For more information on scaling, see [Scaling options for applications in AKS](concepts-scale.md).

-In AKS, the VM image for your cluster's nodes is based on Ubuntu Linux, [Azure Linux](use-azure-linux.md), or Windows Server 2019. When you create an AKS cluster or scale out the number of nodes, the Azure platform automatically creates and configures the requested number of VMs. Agent nodes are billed as standard VMs, so any VM size discounts (including [Azure reservations][reservation-discounts]) are automatically applied.

-For managed disks, the default disk size and performance will be assigned according to the selected VM SKU and vCPU count. For more information, see [Default OS disk sizing](cluster-configuration.md#default-os-disk-sizing).

-If you need advanced configuration and control on your Kubernetes node container runtime and OS, you can deploy a self-managed cluster using [Cluster API Provider Azure][cluster-api-provider-azure].

-To find a node's allocatable resources, run:

-To maintain node performance and functionality, AKS reserves resources on each node. As a node grows larger in resources, the resource reservation grows due to a higher need for management of user-deployed pods.

-> Using AKS add-ons such as Container Insights (OMS) will consume additional node resources.

-Two types of resources are reserved:

-Reserved CPU is dependent on node type and cluster configuration, which may cause less allocatable CPU due to running additional features.

-Memory utilized by AKS includes the sum of two values.

-1. **`kubelet` daemon** has the *memory.available<100Mi* eviction rule by default. This ensures that a node always has at least 100Mi allocatable at all times. When a host is below that available memory threshold, the `kubelet` triggers the termination of one of the running pods and frees up memory on the host machine.

-1. **`kubelet` daemon** is installed on all Kubernetes agent nodes to manage container creation and termination. By default on AKS, `kubelet` daemon has the *memory.available<750Mi* eviction rule, ensuring a node must always have at least 750Mi allocatable at all times. When a host is below that available memory threshold, the `kubelet` will trigger to terminate one of the running pods and free up memory on the host machine.

- * 2% of any memory above 128GB

->[!NOTE]

-> AKS reserves an additional 2GB for system process in Windows nodes that are not part of the calculated memory.

-Memory and CPU allocation rules are designed to do the following:

-The above resource reservations can't be changed.

-### Node pools

-Nodes of the same configuration are grouped together into *node pools*. A Kubernetes cluster contains at least one node pool. The initial number of nodes and size are defined when you create an AKS cluster, which creates a *default node pool*. This default node pool in AKS contains the underlying VMs that run your agent nodes.

-> To ensure your cluster operates reliably, you should run at least two (2) nodes in the default node pool.

-For more information about how to use multiple node pools in AKS, see [Create multiple node pools for a cluster in AKS][use-multiple-node-pools].

-### Node selectors

-In an AKS cluster with multiple node pools, you may need to tell the Kubernetes Scheduler which node pool to use for a given resource. For example, ingress controllers shouldn't run on Windows Server nodes.

-Node selectors let you define various parameters, like node OS, to control where a pod should be scheduled.

-For more information on how to control where pods are scheduled, see [Best practices for advanced scheduler features in AKS][operator-best-practices-advanced-scheduler].

-When you create an AKS cluster, you need to specify a resource group to create the cluster resource in. In addition to this resource group, the AKS resource provider also creates and manages a separate resource group called the node resource group. The *node resource group* contains the following infrastructure resources:

-The node resource group is assigned a name by default, such as *MC_myResourceGroup_myAKSCluster_eastus*. During cluster creation, you also have the option to specify the name assigned to your node resource group. When you delete your AKS cluster, the AKS resource provider automatically deletes the node resource group.

-If you modify or delete Azure-created tags and other resource properties in the node resource group, you could get unexpected results, such as scaling and upgrading errors. As AKS manages the lifecycle of infrastructure in the Node Resource Group, any changes will move your cluster into an [unsupported state][aks-support].

-A common scenario where customers want to modify resources is through tags. AKS allows you to create and modify tags that are propagated to resources in the Node Resource Group, and you can add those tags when [creating or updating][aks-tags] the cluster. You might want to create or modify custom tags, for example, to assign a business unit or cost center. This can also be achieved by creating Azure Policies with a scope on the managed resource group.

-Modifying any **Azure-created tags** on resources under the node resource group in the AKS cluster is an unsupported action, which breaks the service-level objective (SLO). For more information, see [Does AKS offer a service-level agreement?][aks-service-level-agreement]

-To reduce the chance of changes in the node resource group affecting your clusters, you can enable node resource group lockdown to apply a deny assignment to your AKS resources. More information can be found in [Cluster configuration in AKS][configure-nrg].

-Kubernetes uses *pods* to run an instance of your application. A pod represents a single instance of your application.

-Pods typically have a 1:1 mapping with a container. In advanced scenarios, a pod may contain multiple containers. Multi-container pods are scheduled together on the same node, and allow containers to share related resources.

-When you create a pod, you can define *resource requests* to request a certain amount of CPU or memory resources. The Kubernetes Scheduler tries to meet the request by scheduling the pods to run on a node with available resources. You can also specify maximum resource limits to prevent a pod from consuming too much compute resource from the underlying node. Best practice is to include resource limits for all pods to help the Kubernetes Scheduler identify necessary, permitted resources.

-A pod is a logical resource, but application workloads run on the containers. Pods are typically ephemeral, disposable resources. Individually scheduled pods miss some of the high availability and redundancy Kubernetes features. Instead, pods are deployed and managed by Kubernetes *Controllers*, such as the Deployment Controller.

-A *deployment* represents identical pods managed by the Kubernetes Deployment Controller. A deployment defines the number of pod *replicas* to create. The Kubernetes Scheduler ensures that additional pods are scheduled on healthy nodes if pods or nodes encounter problems.

-You can update deployments to change the configuration of pods, container image used, or attached storage. The Deployment Controller:

-Most stateless applications in AKS should use the deployment model rather than scheduling individual pods. Kubernetes can monitor deployment health and status to ensure that the required number of replicas run within the cluster. When scheduled individually, pods aren't restarted if they encounter a problem, and aren't rescheduled on healthy nodes if their current node encounters a problem.

-You don't want to disrupt management decisions with an update process if your application requires a minimum number of available instances. *Pod Disruption Budgets* define how many replicas in a deployment can be taken down during an update or node upgrade. For example, if you have *five (5)* replicas in your deployment, you can define a pod disruption of *4 (four)* to only allow one replica to be deleted or rescheduled at a time. As with pod resource limits, best practice is to define pod disruption budgets on applications that require a minimum number of replicas to always be present.

-Deployments are typically created and managed with `kubectl create` or `kubectl apply`. Create a deployment by defining a manifest file in the YAML format.

-The following example creates a basic deployment of the NGINX web server. The deployment specifies *three (3)* replicas to be created, and requires port *80* to be open on the container. Resource requests and limits are also defined for CPU and memory.

-| `.metadata.name` | Specifies the name of the deployment. This file will run the *nginx* image from Docker Hub. |

-| `.spec.replicas` | Specifies how many pods to create. This file will create three duplicate pods. |

-| `.spec.spec.resources.limits` | Specifies the maximum amount of compute resources allowed. This limit is enforced by the kubelet. |

-| `.spec.spec.resources.limits.cpu` | Specifies the maximum amount of CPU allowed. This limit is enforced by the kubelet. |

-| `.spec.spec.resources.limits.memory` | Specifies the maximum amount of memory allowed. This limit is enforced by the kubelet. |

-More complex applications can be created by including services (such as load balancers) within the YAML manifest.

-[Helm][helm] is commonly used to manage applications in Kubernetes. You can deploy resources by building and using existing public Helm *charts* that contain a packaged version of application code and Kubernetes YAML manifests. You can store Helm charts either locally or in a remote repository, such as an [Azure Container Registry Helm chart repo][acr-helm].

-Using the Kubernetes Scheduler, the Deployment Controller runs replicas on any available node with available resources. While this approach may be sufficient for stateless applications, the Deployment Controller isn't ideal for applications that require:

-Two Kubernetes resources, however, let you manage these types of applications:

-Modern application development often aims for stateless applications. For stateful applications, like those that include database components, you can use *StatefulSets*. Like deployments, a StatefulSet creates and manages at least one identical pod. Replicas in a StatefulSet follow a graceful, sequential approach to deployment, scale, upgrade, and termination. The naming convention, network names, and storage persist as replicas are rescheduled with a StatefulSet.

-Define the application in YAML format using `kind: StatefulSet`. From there, the StatefulSet Controller handles the deployment and management of the required replicas. Data is written to persistent storage, provided by Azure Managed Disks or Azure Files. With StatefulSets, the underlying persistent storage remains, even when the StatefulSet is deleted.

-Replicas in a StatefulSet are scheduled and run across any available node in an AKS cluster. To ensure at least one pod in your set runs on a node, you use a DaemonSet instead.

-For specific log collection or monitoring, you may need to run a pod on all nodes or a select set of nodes. You can use *DaemonSets* to deploy to one or more identical pods. The DaemonSet Controller ensures that each node specified runs an instance of the pod.

-The DaemonSet Controller can schedule pods on nodes early in the cluster boot process, before the default Kubernetes scheduler has started. This ability ensures that the pods in a DaemonSet are started before traditional pods in a Deployment or StatefulSet are scheduled.

-Like StatefulSets, a DaemonSet is defined as part of a YAML definition using `kind: DaemonSet`.

-> If using the [Virtual Nodes add-on](virtual-nodes-cli.md#enable-the-virtual-nodes-addon), DaemonSets will not create pods on the virtual node.

-Kubernetes resources, such as pods and deployments, are logically grouped into a *namespace* to divide an AKS cluster and create, view, or manage access to resources. For example, you can create namespaces to separate business groups. Users can only interact with resources within their assigned namespaces.

-When you create an AKS cluster, the following namespaces are available:

-| *default* | Where pods and deployments are created by default when none is provided. In smaller environments, you can deploy applications directly into the default namespace without creating additional logical separations. When you interact with the Kubernetes API, such as with `kubectl get pods`, the default namespace is used when none is specified. |

-| *kube-system* | Where core resources exist, such as network features like DNS and proxy, or the Kubernetes dashboard. You typically don't deploy your own applications into this namespace. |

-| *kube-public* | Typically not used, but can be used for resources to be visible across the whole cluster, and can be viewed by any user. |

-This article covers some of the core Kubernetes components and how they apply to AKS clusters. For more information on core Kubernetes and AKS concepts, see the following articles:

-* You can connect to and expose applications internally or externally.

-* You can build highly available applications by load balancing your applications.

-## Services

-To simplify the network configuration for application workloads, Kubernetes uses *Services* to logically group a set of pods together and provide network connectivity. You can specify a Kubernetes *ServiceType* to define the type of Service you want. For example, if you want to expose a Service on an external IP address outside of your cluster. For more information, see the Kubernetes documentation on [Publishing Services (ServiceTypes)][service-types].

-The following ServiceTypes are available:

-* **ClusterIP**

-

- ClusterIP creates an internal IP address for use within the AKS cluster. The ClusterIP Service is good for *internal-only applications* that support other workloads within the cluster. ClusterIP is the default used if you don't explicitly specify a type for a Service.

- ![Diagram showing ClusterIP traffic flow in an AKS cluster][aks-clusterip]

-* **NodePort**

- NodePort creates a port mapping on the underlying node that allows the application to be accessed directly with the node IP address and port.

- ![Diagram showing NodePort traffic flow in an AKS cluster][aks-nodeport]

-* **LoadBalancer**

- LoadBalancer creates an Azure load balancer resource, configures an external IP address, and connects the requested pods to the load balancer backend pool. To allow customers' traffic to reach the application, load balancing rules are created on the desired ports.

- ![Diagram showing Load Balancer traffic flow in an AKS cluster][aks-loadbalancer]

- For HTTP load balancing of inbound traffic, another option is to use an [Ingress controller](#ingress-controllers).

-* **ExternalName**

- Creates a specific DNS entry for easier application access.

-Either the load balancers and services IP address can be dynamically assigned, or you can specify an existing static IP address. You can assign both internal and external static IP addresses. Existing static IP addresses are often tied to a DNS entry.

-You can create both *internal* and *external* load balancers. Internal load balancers are only assigned a private IP address, so they can't be accessed from the Internet.

-Learn more about Services in the [Kubernetes docs][k8s-service].

-* ***Kubenet* networking**

-* ***Azure Container Networking Interface (CNI)* networking**

-Additionally, Cilium enforces network policies by default, without requiring a separate network policy engine. Azure CNI Powered by Cilium can scale beyond [Azure Network Policy Manager's limits of 250 nodes / 20-K pod][use-network-policies] by using ePBF programs and a more efficient API object structure.

-* **kubenet**

- * Conserves IP address space.

- * Uses Kubernetes internal or external load balancers to reach pods from outside of the cluster.

- * You manually manage and maintain user-defined routes (UDRs).

- * Maximum of 400 nodes per cluster.

-* **Azure CNI**

-* The Azure platform can automatically create and configure the virtual network resources when you create an AKS cluster.

-* You can manually create and configure the virtual network resources and attach to those resources when you create your AKS cluster.

-* If you manually create the virtual network resources for an AKS cluster, you're supported when configuring your own UDRs or service endpoints.

-* If the Azure platform automatically creates the virtual network resources for your AKS cluster, you can't manually change those AKS-managed resources to configure your own UDRs or service endpoints.

-* Easy configuration of managed NGINX Ingress controllers based on Kubernetes NGINX Ingress controller.

-* Integration with Azure DNS for public and private zone management.

-* SSL termination with certificates stored in Azure Key Vault.

-* Back-end applications are only exposed to required frontend services.

-* Database components are only accessible to the application tiers that connect to them.
