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

If you have something like this in your docker-compose.yml

version: "3.7"

services:

  app:
    build:
      context: .
      dockerfile: docker/app/Dockerfile
    ports:
    - 8000:8000
    volumes:
        - ./:/usr/src/app
    depends_on:
      - db

  db:
    image: postgres
    restart: always
    environment:
      POSTGRES_USER: docker
      POSTGRES_PASSWORD: docker
      POSTGRES_DB: docker

Then you can simple run...

~$ docker-compose exec app python manage.py makemigrations
~$ docker-compose exec app python manage.py migrate
