-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](https://code.visualstudio.com/docs/python/tutorial-deploy-containers).

+## Navigation
 
 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`).
