- Download source code as zip from gitlab instead of git+https because speed.
- Check if the $DATABASE_URL is not defined, use a default sqlite database.
- Use dj-database-url package to set database in django settings using
DATABASE_URL environment variable.
- Use UWSGI_LOG_URL as the URL for UWSGI logging and set it to a default value
if it has not been defined.
This commit adds a lot of new code including the mailman's web
frontend. It includes a configuration file which can later be
configured to run required configs.
Also, the docker-compose file spins off the containers, sets up
appropriate volumes and links.
