Docker化Django+Celery+RabbitMQ项目遇域名解析失败问题求助

我正在尝试将集成Celery与RabbitMQ的Django项目进行Docker化部署，已编写Docker Compose文件，但无法正常运行。启动Docker Compose容器后，所有容器均显示正常运行，但在Django项目中执行Celery任务时，出现以下错误：

[Errno -3] Temporary failure in name resolution

我的Docker Compose配置 #

services:
  rabbitmq:
    image: rabbitmq:latest
    networks:
      - main
    ports:
      - "5672:5672"
    restart: always
    environment:
      - RABBITMQ_DEFAULT_USER=guest
      - RABBITMQ_DEFAULT_PASS=guest

  celery_worker:
    image: python:3.10
    command: celery -A zwitter worker -l INFO
    build:
      context: .
    depends_on:
      - app
      - rabbitmq
    environment:
      - CELERY_BROKER_URL=amqp://guest:guest@rabbitmq:5672/
    networks:
      - main
    restart: always

  redis:
    image: redis:latest
    ports:
      - "6379:6379"
    volumes:
      - cache:/data
    command: redis-server --save 60 1
    restart: always

  app:
    image: python:3.10
    build: .
    command: bash -c "python manage.py makemigrations && python manage.py migrate && python manage.py runserver 0.0.0.0:8000"
    volumes:
      - .:/src/
    ports:
      - "8000:8000"

networks:
  main:

volumes:
  cache:

已尝试的排查步骤 #

• 确认RabbitMQ服务器已运行且可访问
• 确认Celery Worker已配置为连接正确的RabbitMQ服务器
• 检查Celery Worker容器与RabbitMQ服务器之间的网络连接
