docker-compose "depends_on", but with "docker run"

Question

How can I implement the below docker-compose code, but using the docker run command? I am specifically interested in the depends_on part.

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

Answer 1

depends_on: doesn't map to a docker run option. When you have your two docker run commands you need to make sure you put them in the right order.

docker build -t web_image .
docker network create some_network
docker run --name db --net some_network postgres
# because this depends_on: [db] it must be second
docker run --name web --net some_network ... web_image ...
