How to deploy django-q with docker?

Assume this simple docker-compose file

version: "3.9"
   
services:  
  redis:
    image: redis:alpine
    ports:
      - 6379:6379

  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - redis

How can i add django-q process to handle all requests from web container? I could probably build same image with different command such as python manage.py qcluster but I dont think this solution si elegant. Could you suggest some approach how to do that?

You need to run 2 docker containers. One for application server and one for django-q service. Your dockercompose file will look like this.

version: "3.9"
   
services:  
  redis:
    image: redis:alpine
    ports:
      - 6379:6379

  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - redis
  django-q:
    build: .
    command: python manage.py qcluster
    volumes:
      - .:/code
    depends_on:
      - redis

I have a question to this topic:

How can I serve environment variables (with os.environ[]) from a file to the settings.py with docker? It is working for my app but Django Q does not take those values and gave me errors like:

djangoq_1 | raise ImproperlyConfigured(“The SECRET_KEY setting must not be empty.”) djangoq_1 | django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

djangoq_1 | ALLOWED_HOSTS = os.environ.get(“DJANGO_ALLOWED_HOSTS”).split(" ") djangoq_1 | AttributeError: ‘NoneType’ object has no attribute ‘split’
