agent-framework/python/samples/04-hosting/azure_functions

These are common instructions for setting up your environment for every sample in this directory. These samples illustrate the Durable extensibility for Agent Framework running in Azure Functions.

All of these samples are set up to run in Azure Functions. Azure Functions has a local development tool called CoreTools which we will set up to run these samples locally.

Environment Setup

1. Install dependencies and create appropriate services

• Install Azure Functions Core Tools 4.x

• Install Azurite storage emulator

• Create an Azure OpenAI resource. Note the Azure OpenAI endpoint, deployment name, and the key (or ensure you can authenticate with AzureCliCredential).

• Install a tool to execute HTTP calls, for example the REST Client extension

• [Optionally] Create an Azure Function Python app to later deploy your app to Azure if you so desire.

2. Create and activate a virtual environment

Windows (PowerShell):

python -m venv .venv
.venv\Scripts\Activate.ps1

Linux/macOS:

python -m venv .venv
source .venv/bin/activate

3. Running the samples

• Start the Azurite emulator

• Inside each sample:

  • Install Python dependencies – from the sample directory, run pip install -r requirements.txt (or the equivalent in your active virtual environment).

  • Copy local.settings.json.template to local.settings.json, then update AZURE_OPENAI_ENDPOINT and AZURE_OPENAI_CHAT_DEPLOYMENT_NAME for Azure OpenAI authentication. The samples use AzureCliCredential by default, so ensure you're logged in via az login.

    • Alternatively, you can use API key authentication by setting AZURE_OPENAI_API_KEY and updating the code to use AzureOpenAIChatClient() without the credential parameter.
    • Keep TASKHUB_NAME set to default unless you plan to change the durable task hub name.

  • Run the command func start from the root of the sample

  • Follow each sample's README for scenario-specific steps, and use its demo.http file (or provided curl examples) to trigger the hosted HTTP endpoints.
