This sample contains the completed program from the tutorial, 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.
The 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 startup.txt).
Contributions to the sample are welcome. When submitting changes, also consider submitting matching changes to the tutorial, the source file for which is tutorial-flask.md.
