Django的通道和码头工人，撰写错误

Question

当通过码头工人和码头工人，撰写的runserver运行，我得到这个错误，我无法连接到Django的：

django_1   | 2017-01-09 08:24:44,328 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive

在本地运行，一切都运行正常。 这里是我的requirements.txt：

Django的== 1.10.4 psycopg2 == 2.6.2 渠道== 0.17.3 ASGI，Redis的== 1.0.0

而这里的我的码头 - 撰写文件：

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" 

任何想法？

Answer 1

原来我使用的是daphne的1.0.0版本，与此同时我使用的是老版本的django频道，它们不兼容。更新两个固定的错误。

Answer 2

您的容器没有相互链接。尝试将它们联合到网络中。

version: '2' 
    services: 
    redis: 
     image: redis:3.0-alpine 
     networks: 
     - django-network 

    postgres: 
     image: postgres 
     networks: 
     - django-network 

    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 
     networks: 
     - django-network 

    django-migration: 
     build: ../backend 
     command: python backend/manage.py migrate 
     volumes: 
      - ../backend:/backend 
     depends_on: 
      - postgres 
     networks: 
     - django-network 

    client:

     command: bash -c "cd src && npm start" 
     ports: 
      - "3000:3000"
