How do you perform Django database migrations when using Docker-Compose?

Question

I have set up a Docker Django/PostgreSQL app closely following the Django Quick Start instructions on the Docker site.

The first time I run Django\'s manage.py migr

Answer 1

Have your stack running then fire off a one shot docker-compose run command. E.g

#assume django in container named web
docker-compose run web python3 manage.py migrate

This works great for the built-in (default) SQLite database, but also for an external dockerized database that's listed as dependency. Here's an example docker-compose.yaml file

version: '3'

services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db
