无法将芹菜与docker上的rabbitmq服务器连接

Question

我试图创建docker-撰写文件，将运行django apache服务器与芹菜任务，并使用Rabbitmq作为消息经纪。我的问题是芹菜不能连接到Rabbitmq。我得到了这个错误：

[2021-02-18 08:11:44,769：错误/主进程]消费者：无法连接到amqp：//客人：**@Rabbitmq： 5672//：[Errno 111]连接拒绝。

这也是我第一次创建docker图像，所以我可能在那里犯了很多错误。

我的docker撰写文件：

version: "3.8"

services:
  server: &server
    build:
      context: .
    environment:
      - PYTHONUNBUFFERED=1
      - CELERY_BROKER=amqp://admin:password@rabbitmq:5672//
    volumes:
      - .:/var/www/html/public
    ports:
      - 80:80
    command:
      ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]
    depends_on:
      - rabbitmq
      - celery_beat
    networks:
      - main
  
  rabbitmq:
    container_name : rabbitmq
    image: rabbitmq:3.8
    hostname: rabbitmq
    ports:
      - 5672:5672
    networks:
      - main
    environment:   
    - RABBITMQ_DEFAULT_USER=admin
    - RABBITMQ_DEFAULT_PASS=password


  celery_worker:
    <<: *server
    hostname: rabbitmq
    command: celery -A public worker -l INFO
    ports: []
    networks:
      - main
    depends_on:
      - rabbitmq
    environment:
    #- RABBITMQ_DEFAULT_USER=admin
    #- RABBITMQ_DEFAULT_PASS=password
    - CELERY_BROKER=amqp://admin:password@rabbitmq:5672//

networks:
  main:

Dockerfile：

FROM ubuntu:latest

ENV PYTHONUNBUFFERED=1

RUN apt-get -y update
RUN DEBIAN_FRONTEND=noninteractive apt-get install -y apache2 python3.8 python3-pip libapache2-mod-wsgi-py3

RUN pip3 install --upgrade pip

ADD requirements.txt .

RUN pip install -r requirements.txt

ADD ./scraper_project.conf /etc/apache2/sites-available/scraper_project.conf
ADD . /var/www/html/public

WORKDIR /var/www/html/public

RUN chown -R :www-data .
RUN chmod -R 775 . 

EXPOSE 80

RUN a2ensite scraper_project
RUN a2dissite 000-default

CMD ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]

芹菜设置：

CELERY_BROKER_URL = os.environ['CELERY_BROKER']

Answer 1

固定。问题是我在芹菜工人中设置了主机名。如果有人有类似的问题只是删除主机名：Rabbitmqcelery_worker。
