docker および docker-compose を介して runserver を実行すると、次のエラーが発生し、django に接続できません。

ローカルで実行すると、すべて正常に実行されます。これが私のrequirements.txtです：

Django==1.10.4 psycopg2==2.6.2 チャンネル==0.17.3 asgi-redis==1.0.0

そして、これが私のdocker-composeファイルです：

version: '2' 
  services:
    redis:
      image: redis:3.0-alpine
    postgres:
        image: postgres
    django:
        build: ../backend
        command:  python backend/manage.py runserver 0.0.0.0:8000
        volumes:
            - ../backend:/backend
        ports:
            - "8000:8000"
        depends_on:
            - postgres
            - redis
            - django-migration
    django-migration:
        build: ../backend
        command: python backend/manage.py migrate
        volumes:
          - ../backend:/backend
        depends_on:
          - postgres
    client:
        image: node
        command: bash -c "cd src && npm start"
        ports:
            - "3000:3000"

何か案は？

コンテナが相互にリンクしていません。それらをネットワークに結合してみてください。

  services:
    redis:

      networks:
       - django-network

    postgres:

        networks:

        command:  python backend/manage.py runserver 0.0.0.0:8000
        volumes:
            - ../backend:/backend
        ports:
