【问题描述】：

我正在尝试使用 Django 设置 Docker 容器。我的 Docker 文件是：

FROM python:3.7-alpine
MAINTAINER Freshness Productions

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt
RUN apk add --update --no-cache postgresql-client
RUN apk add --update --no-cache --virtual .tmp-build-deps \
    gcc libc-dev linux-headers postgresql-dev
RUN pip install -r /requirements.txt
RUN apk del .tmp-build-deps

RUN mkdir /app
WORKDIR /app
COPY ./app /app

RUN adduser -D user
USER user

RUN rabbitmqctl add_user test testpass1
RUN rabbitmqctl add_vhost myvhost
RUN rabbitmqctl set_permissions -p myvhost test ".*" ".*" ".*"
RUN rabbitmq-server

我的 docker-compose.yml 是：

version: "3"

services:
  app:
    build:
      context: .
    image: &app app
    ports:
      - "8000:8000"
    volumes:
      - ./app:/app
    command: >
      sh -c "python manage.py wait_for_db &&
             python manage.py migrate &&
             python manage.py runserver 0.0.0.0:8000
             export C_FORCE_ROOT='true'
             celery -A app beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler"
    env_file: &envfile
      - env.env
    depends_on:
      - db
      - broker

  db:
    image: postgres:10-alpine
    environment:
      - POSTGRES_DB=app
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=supersecretpassword

  worker:
    build: .
    image: *app
    restart: "no"
    env_file: *envfile
    command: sh -c "celery -A app worker --loglevel=info"
    volumes:
      - ./app:/app
    depends_on:
      - broker

  broker:
    image: rabbitmq:3
    env_file: *envfile
    ports:
      - 5672:5672

除了我在 docker-compose 中使用两个不同的图像之外，我没有看到我需要做什么？这有关系吗？我得到错误：

ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [Errno 111] Connection refused.

当我尝试运行 docker-compose up 时

【问题讨论】：

您似乎正在尝试连接到 RabbitMQ 的本地主机。尝试连接到代理而不是本地主机（127.0.0.1），看看是否存在问题
我不知道怎么做？我的环境文件中有一个环境变量 CELERY_BROKER=amqp://guest:guest@broker:5672
你找到解决办法了吗？>
使用您的 docker 设置，我收到此错误 /bin/sh: rabbitmqctl: not found ERROR: Service 'worker' failed to build: The command '/bin/sh -c rabbitmqctl add_user test testpass1'返回一个非零代码：127 你能帮忙吗？

【解决方案1】：

在那里你可以找到这个配置，它可以完美地与 RabbitMQ、Python Django、MYQL、Celery 和 Celery Beat 配合使用。

如果您愿意，请不要忘记投票。谢谢。
