Python/Flask tutorial sample for Visual Studio Code
- This sample contains the completed program from the tutorial, make sure to visit the link: Using Flask in Visual Studio Code. Intermediate steps are not included.
- It also contains the Dockerfile and uwsgi.ini files necessary to build a container with a production server. The resulting image works both locally and when deployed to Azure App Service. See Deploy Python using Docker containers.
- You can also deploy this sample to Azure App Service using GitHub Actions. See https://blog.siliconvalve.com/2019/03/22/use-github-actions-to-deploy-a-python-flask-web-app-to-azure-app-service-on-linux/.
startup.py file, for its part, is specifically for deploying to Azure App Service on Linux without containers. Because the app code is in its own module in the
hello_app folder (which has an
__init__.py), trying to start the Gunicorn server within App Service on Linux produces an "Attempted relative import in non-package" error. The
startup.py file, therefore, is just a shim to import the app object from the
hello_app module, which then allows you to use startup:app in the Gunicorn command line (see
