Django频道和泊坞窗 – 撰写错误

当通过docker和docker-compose运行runserver时，出现这个错误，我无法连接到django：

django_1 | 2017-01-09 08:24:44,328 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive django_1 | 2017-01-09 08:24:44,329 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive django_1 | 2017-01-09 08:24:44,331 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive django_1 | 2017-01-09 08:24:44,331 - INFO - worker - Listening on channels http.request, websocket.connect, websocket.disconnect, websocket.receive django_1 | Unhandled exception in thread started by <function wrapper at 0x7ff06bee5d70> django_1 | Traceback (most recent call last): django_1 | File "/usr/local/lib/python2.7/site-packages/django/utils/autoreload.py", line 226, in wrapper django_1 | fn(*args, **kwargs) django_1 | File "/usr/local/lib/python2.7/site-packages/channels/management/commands/runserver.py", line 84, in inner_run django_1 | Performing system checks... django_1 | django_1 | System check identified no issues (0 silenced). django_1 | January 09, 2017 - 08:24:44 django_1 | Django version 1.10.4, using settings 'backend.settings' django_1 | Starting Channels development server at http://0.0.0.0:8000/ django_1 | Channel layer default (asgi_redis.core.RedisChannelLayer) django_1 | Quit the server with CONTROL-C. django_1 | ws_protocols=getattr(settings, 'CHANNELS_WS_PROTOCOLS', None), django_1 | File "/usr/local/lib/python2.7/site-packages/daphne/server.py", line 41, in __init__ django_1 | ''' % self.__class__.__name__) django_1 | DeprecationWarning: django_1 | The host/port/unix_socket/file_descriptor keyword arguments to Server are deprecated. django_1 | 

在本地运行时，一切运行正常。 这是我的requirements.txt文件：

Django == 1.10.4 psycopg2 == 2.6.2 channels == 0.17.3 asgi-redis == 1.0.0

这里是我的docker-compose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" 

有任何想法吗？

Answer 1

原来我使用的是daphne的1.0.0版本，同时我使用的是旧版本的django频道，而且它们不兼容。 更新两个固定的错误。

Answer 2

你的容器没有链接。 尝试将他们联合起来。

 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: image: node command: bash -c "cd src && npm start" ports: - "3000:3000" networks: - django-network networks: tele-cluster-network: driver: bridge
