QuickStart for bigger projects structured as a Python package

Note: You can download the example-flask-package-python3.6.zip project example and use it as an example or template for your project from the section Examples above.

You should be able to follow the same instructions as in the "QuickStart" section above, with some minor modifications:

    Instead of putting your code in the app/ directory, put it in a directory app/app/.
    Add an empty file __init__.py inside of that app/app/ directory.
    Add a file uwsgi.ini inside your app/ directory (that is copied to /app/uwsgi.ini inside the container).
    In your uwsgi.ini file, add:

[uwsgi]
module = app.main
callable = app

The explanation of the uwsgi.ini is as follows:

    The module in where my Python web app lives is app.main. So, in the package app (/app/app), get the main module (main.py).
    The Flask web application is the app object (app = Flask(__name__)).

Your file structure would look like:

.
├── app
│   ├── app
│   │   ├── __init__.py
│   │   ├── main.py
│   └── uwsgi.ini
└── Dockerfile

...instead of:

.
├── app
│   ├── main.py
└── Dockerfile

...after that, everything should work as expected. All the other instructions would apply normally.
