Example using Docker, Django, multiple Postgres databases, NginX, Gunicorn, pipenv, GitLab CI and tox

This is a Docker setup for a web application based on Django.

• The Django application is served by Gunicorn (WSGI application).
• We use NginX as reverse proxy and static files server. Static and media files are persistently stored in volumes.
• Multiple Postgres databases can be used. Data are persistently stored in volumes.
• Python dependencies are managed through pipenv, with Pipfile and Pipfile.lock.
• Support for multiple environment settings (variable DJANGO_SETTINGS_MODULE is passed to the djangoapp service).
• Tests are run using tox, pytest, and other tools such as safety, bandit, isort and prospector.
• Continuous Integration is configured for GitLab with .gitlab-ci.yml. CI follows a Build-Test-Release flow. WARNING: this part is not fully functional yet.

Also a Makefile is available for convenience. You might need to use sudo make instead of just make because docker and docker-compose commands often needs admin privilege.
