Python Django Dockerfile

When setting up a Python/Django project, I like to do a few things:

• use poetry to manage dependencies and virtualenv
• use poe to manage tasks (similar to node's scripts)
• split the django settings.py into multiple files, with one per environment (similar to Elixir compile-time config)
• use gunicorn and whitenoise to serve the application
• use a multi-stage Dockerfile making heavy use of the docker layer cache to avoid running intensive steps needlessly
• use django-tailwind and django-anymail

    yield_!(2);
