Deployment with Docker-Compose

Using the docker-compose of the production environment of Django-Cookie-Cutter

docker-compose -f docker-compose.production.yml run --rm django python manage.py migrate
docker-compose -f docker-compose.production.yml run --rm django python manage.py createsuperuser
docker-compose -f docker-compose.production.yml --env-file .envs/.production/.django up
