Publish to Azure App Service
Python support on Azure App Service for Windows is officially deprecated. As a result, the Publish command in Visual Studio is officially supported only for an IIS target, and remote debugging on Azure App Service is no longer officially supported.
However, Publishing to App Service on Windows features still works for the time being, as the Python extensions for App Service on Windows remain available but will not be serviced or updated.
Publish to App Service on Linux using Git deploy
Git deploy connects an App Service on Linux to a specific branch of a Git repository. Committing code to that branch automatically deploys to the App Service, and App Service automatically installs any dependencies listed in requirements.txt. In this case, App Service on Linux runs your code in a pre-configured container image that uses the Gunicorn web server. At present, this service is in Preview and not supported for production use.
For more information, see the following articles in the Azure documentation:
- Quickstart: Create a Python web app in App Service provides a short walkthrough of the Git deploy process using a simple Flask app and deployment from a local Git repository.
- How to configure Python describes the characteristics of the App Service on Linux container and how to customize the Gunicorn startup command for your app.
Publish to App Service on Linux using containers
Instead of relying on the pre-built container with App Service on Linux, you can provide your own container. This option allows you to choose which web servers you use and to customize the container's behavior.
There are two options to build, manage, and push containers:
Use Visual Studio Code and the Docker extension, as described on Deploy Python using Docker Containers. Even if you don't use Visual Studio Code, the article provides helpful details on building container images for Flask and Django apps using the production-ready uwsgi and nginx web servers. You can then deploy those same container using the Azure CLI.
Use the command line and Azure CLI, as described on Use a custom Docker image in the Azure documentation. This guide is generic, however, and not specific to Python.
Publish to IIS
From Visual Studio, you can publish to a Windows virtual machine or other IIS-capable computer with the Publish command. When using IIS, be sure to create or modify a web.config file in the app that tells IIS where the find the Python interpreter. For more information, see Configure web apps for IIS.
