Tools](https://learn.microsoft.com/azure/azure-functions/functions-run-local) (version 4.x or later) +- [Azure CLI](https://learn.microsoft.com/cli/azure/install-azure-cli) installed and authenticated (`az login`) or an API key for the Azure OpenAI service +- [Azure OpenAI Service](https://learn.microsoft.com/azure/ai-services/openai/how-to/create-resource) with a deployed model (gpt-4o-mini or

DTS also allows you to view the status of orchestrations and their inputs and outputs from a web UI. + +To run the Durable Task Scheduler locally, you can use the following `docker` command: + +```bash +docker run -d --name dts-emulator -p 8080:8080 -p 8082:8082 mcr.microsoft.com/dts/dts-emulator:latest +``` + +The DTS dashboard will be available at `http://localhost:8080`. + +### Start the Azure Storage Emulator + +All Function apps require an Azure Storage account to store functions-specific state. You can use the Azure Storage Emulator to run a local instance of the Azure Storage service. + +You can run the Azure Storage emulator locally as a standalone process or via a Docker container. + +#### Docker + +```bash +docker run -d --name storage-emulator -p 10000:10000 -p 10001:10001 -p 10002:10002 mcr.microsoft.com/azure-storage/azurite +``` + +#### Standalone + +```bash +npm install -g azurite +azurite +``` + +### Environment Configuration + +Each sample has its own `local.settings.json` file that contains the environment variables for the sample. You'll need to update the `local.settings.json` file with the correct values for your Azure OpenAI resource. + +```json +{ + "Values": { + "AZURE_OPENAI_ENDPOINT": "https://your-resource.openai.azure.com/", + "AZURE_OPENAI_DEPLOYMENT": "your-deployment-name" + } +} +``` + +Alternatively, you can set the environment variables in the command line. + +### Bash (Linux/macOS/WSL) + +```bash +export AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/" +export AZURE_OPENAI_DEPLOYMENT="your-deployment-name" +``` + +### PowerShell + +```powershell +$env:AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/" +$env:AZURE_OPENAI_DEPLOYMENT="your-deployment-name" +``` + +These environment variables, when set, will override the values in the `local.settings.json` file, making it convenient to test the sample without having to update the `local.settings.json` file. + +### Start the Azure Functions app + +Navigate to the sample directory and start the Azure Functions app: + +```bash +cd dotnet/samples/AzureFunctions/01_SingleAgent +func start +``` + +The Azure Functions app will be available at `http://localhost:7071`. + +### Test the Azure Functions app + +The README.md file in each sample directory contains instructions for testing the sample. Each sample also includes a `demo.http` file that can be used to test the sample from the command line. These files can be opened in VS Code with the [REST Client](https://marketplace.visualstudio.com/items?itemName=humao.rest-client) extension or in the Visual Studio IDE. + +### Viewing the sample output + +The Azure Functions app logs are displayed in the terminal where you ran `func start`. This is where most agent output will be displayed. You can adjust logging levels in the `host.json` file as needed. + +You can also see the state of agents and orchestrations in the DTS dashboard.
