yaml - Using Docker-Compose, how to execute multiple commands

Question

I want to do something like this where I can run multiple commands in order.

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

Answer 1

Figured it out, use bash -c.

Example:

command: bash -c "python manage.py migrate && python manage.py runserver 0.0.0.0:8000"

Same example in multilines:

command: >
    bash -c "python manage.py migrate
    && python manage.py runserver 0.0.0.0:8000"

Or:

command: bash -c "
    python manage.py migrate
    && python manage.py runserver 0.0.0.0:8000
  "
