Docker Compose | How to configure PostgreSQL or MySQL database with Python Django

In this Docker compose tutorial we start a Django application with Docker Compose and run it in a container. I will then show you how to configure a volume to build a mirrored folder from your computer and the container. This way you can develop on your computer but host the application in a container. Next up we configure first a PostgreSQL database and attach it to Django then build a bassline configuration for MySQL for a Django application. This is a docker compose tutorial for beginners. Take your first steps with Docker containers.

What about production? Do you have the real data stored on the machine, where the app is running? In this case in ./data/db?

For those who are getting error: could not translate host name "db" to address: temporary failure in name resolution
You should consider adding the addiotional configs to your docker-compose file:
db:
image: postgres
ports:
- 5432:5432
volumes:
-
- pgconf:/etc/postgresql
- pglog:/var/log/postgresql
environment:
- POSTGRES_DB=postgres
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgres
container_name: postgres_db
volumes:
pgdata:
driver: local
pgconf:
driver: local
pglog:
driver: local

Hi, anyone with this error ? : raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e)
django-container2 | Error loading psycopg2 module: No module named 'psycopg2'.
(UPDATE Fix) I had to delete my previous app image and create it again so it could install the psycopg2-binary package.
