Deploying Azure Functions with Python 3.7 in Visual Studio Code

Introduction

If you're trying to deploy an Azure Function using Python 3.7 through Visual Studio Code and are facing issues with OS selection during publishing, you're not alone. Many developers encounter this confusion when Azure's default settings seem to favor Windows OS over Linux, especially for Python applications. This guide will guide you through the problem and provide strategies to effectively deploy your Azure Function to the operating system of your choice.

Understanding the Issue

When attempting to publish an Azure Function application using Python 3.7 in Visual Studio Code, you might notice that:

VS Code defaults to Windows OS: The absence of an OS selection option can be frustrating if you're targeting a Linux environment as required by your resource group.

Python 3.7 Compatibility: Azure may not support Python 3.7 on Windows OS, thus leading to this publishing challenge.

For those who have experienced the ease of using Visual Studio, you might recall that it does allow OS selection during deployment, but alas, it does not support Python. This creates a conundrum for Python developers.

Solution Steps

Here’s how to effectively deploy your Azure Function application using Python 3.7 focusing on a Linux environment directly from Visual Studio Code:

Step 1: Ensure Your Function App is Configured for Linux

Create a Function App on Azure: Start by logging in to the Azure portal and creating a new Function App.

Select the OS: While setting up your Function App, ensure that you select Linux as your hosting environment. This is crucial because Python 3.7 is supported on Linux but not on Windows.

Step 2: Deploy Using Command Line

If you've already set up your Function App as outlined above, and you're still facing issues within Visual Studio Code, don't worry. You can directly publish your function app using a command line interface:

Open Your Terminal in VS Code:

You can find the terminal in the top menu bar under View Terminal.

Run the Deployment Command:

Use the following command to publish your Azure Function app:

Replace <FunctionAppName> with the actual name of your Function App.

Step 3: Verify the Deployment

Once you've executed the command, check the Azure portal to confirm that your function app is deployed correctly. You can run a test to ensure the functionality is as expected.

Conclusion

Deploying an Azure Function with Python 3.7 in Visual Studio Code can be tricky, especially when operating system preferences are assumed. By creating your Function App targeting Linux and utilizing the command line for publication, you can easily overcome this challenge. Keep these steps in mind for a smoother deployment experience in the future.

Happy coding!
