Deploy Azure Functions with Visual Studio Code

Home/MSDN Documentation/Azure/Functions/Deploy with VS Code

This guide will walk you through the process of deploying your Azure Functions to the cloud using Visual Studio Code. Visual Studio Code provides a seamless development experience for Azure Functions, allowing you to create, debug, and deploy your functions with ease.

Prerequisites

Steps to Deploy

1

Create or Open Your Function App Project

You can either create a new Azure Functions project in VS Code or open an existing one. To create a new project:

  1. Open Visual Studio Code.
  2. Go to the Azure extension sidebar.
  3. Under the "Functions" section, click the "Create new project..." button.
  4. Follow the prompts to select a folder, language, and template for your function.

If you have an existing project, simply open the folder containing your function app code.

2

Sign in to Azure

Before deploying, ensure you are signed in to your Azure account within VS Code. In the Azure extension sidebar, click "Sign in to Azure..." and follow the authentication prompts.

3

Deploy to Azure

Once your project is ready and you are signed in, you can deploy:

  1. In the Azure extension sidebar, under the "Functions" section, click the "Deploy to Function App..." button (it looks like an upward-pointing arrow).
  2. Select the Azure subscription where you want to deploy your function app.
  3. Choose an existing Function App in Azure or select the option to create a new one.
  4. If creating a new Function App, you will be prompted for details like a unique name, runtime stack (e.g., Node.js, .NET, Python), region, and resource group.
  5. VS Code will now package your function code and deploy it to your selected Azure Function App. You can monitor the deployment progress in the VS Code output window.

Important: Ensure your project is correctly configured for deployment. The Azure Functions extension typically handles this, but always check your host.json and local.settings.json (for local development) files.

4

Verify Deployment

After the deployment is complete, you can verify your function is running in Azure:

  • In the Azure extension sidebar, navigate to your Function App under the "Functions" node.
  • You should see your deployed functions listed.
  • You can also navigate to your Function App in the Azure portal to check its status, logs, and endpoints.

Managing Deployed Functions

The Azure Functions extension in VS Code provides tools for managing your deployed functions:

Tip: For more complex deployments, consider using CI/CD pipelines with Azure DevOps or GitHub Actions. The Azure Functions extension can help you set these up.

Troubleshooting

If you encounter issues during deployment or when running your functions in Azure:
