Question

我有一个django渠道容器和一个芹菜工人，我正在尝试连接到芹菜容器内的django渠道容器，但是，我发现很难连接。我在http://127.0.0.1:8000/上运行了一个django服务器。这就是我的docker-compose文件的样子

web:
  restart: always
  tty: true
  build: ./web/
  working_dir: /data/web/fileshiffty
  expose:
    - "8000"
  ports:
    - "8000:8000"
  links:
    - postgres:postgres
    - redis:redis
  env_file: env
  volumes:
    - ./web:/data/web
  command: bash -c "python3 manage.py runserver 0.0.0.0:8000"
postgres:
  restart: always
  image: postgres:latest
  volumes_from:
    - data
  volumes:
    - ./postgres/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
    - ./backups/postgresql:/backup
  env_file:
    - env
  expose:
    - "5432"
redis:
  restart: always
  image: redis:latest
  expose:
    - "6379"
worker:
    build: ./web/
    working_dir: /data/web/fileshiffty
    command: bash -c "celery -A fileshiffty worker --loglevel=DEBUG"
    volumes:
      - ./web:/data/web
    links:
      - postgres:postgres
      - redis:redis
      - web:web
data:
  restart: always
  image: alpine
  volumes:
    - /var/lib/postgresql
  command: "true"

但是，在我的芹菜任务中，它要求它连接到具有URL ws://127.0.0.1:8000/ws/converter/public/的Web套接字。这就是我的任务的样子

# Create your tasks here
from __future__ import absolute_import, unicode_literals
from celery import shared_task
import img2pdf
import os
import websocket 
import json
import boto
from boto.s3.key import Key

@shared_task
def convert_file_to_pdf(file_name_on_cdn):
    ws = websocket.WebSocket()
    ws.connect('ws://web/ws/converter/public/')
    ws.send(json.dumps({
        'message': '{}'.format(file_name_on_cdn), 
        'progress': 0}))
    # some other stuff

但是，在运行任务时我一直收到以下错误

worker_1    | [2018-03-21 16:19:03,392: ERROR/ForkPoolWorker-2] Task api.tasks.convert_file_to_pdf[2fb26db9-7dd5-4b57-9242-fd61e743952d] raised unexpected: ConnectionRefusedError(111, 'Connection refused')

worker_1    |     sock.connect(address)
worker_1    | ConnectionRefusedError: [Errno 111] Connection refused

很明显它无法连接到网址。我甚至试过设置ws.connect('ws://web/ws/converter/public/')但是，这似乎也没有用。任何帮助，将不胜感激。一直试图弄清楚多少小时的错误

Answer 1

看起来我所要做的就是指定我的Django应用程序运行的端口是端口8000，所以我只需要将ws.connect('ws://web:8000/ws/converter/public/')更改为{{1}}

尝试从docker
