docker - 运行 docker compose 时 pika 异常 amqpconnectionerror 错误

Question

我有一个依赖于rabbitmq 的python docker 容器。我尝试使用 docker-compose 文件链接这两个容器：

version: "3.8"
services:
  rabbitmq:
    image: rabbitmq:3-management
    hostname: my-rabbit
    volumes:
      - ./rabbitmq/etc/configurations.json:/etc/rabbitmq/configurations.json
      - ./rabbitmq/etc/rabbitmq.conf:/etc/rabbitmq/rabbitmq.conf
    ports:
      - 5672:5672
      - 15672:15672
      - 25672:25672
    networks:
      - ihddocker

  notification:
    image: ihdnotification
    restart: on-failure
    links:
      - rabbitmq
    depends_on:
      - rabbitmq
    networks:
      - ihddocker

networks: 
  ihddocker:
    external:
      name: ihddocker

我在 python 应用程序容器中收到以下错误 -

File "broker.py", line 22, in start_consumer
connection = pika.BlockingConnection(message_broker_params)
File "/usr/local/lib/python3.8/site-packages/pika/adapters/blocking_connection.py", line 359, in __init__
self._impl = self._create_connection(parameters, _impl_class)
File "/usr/local/lib/python3.8/site-packages/pika/adapters/blocking_connection.py", line 450, in _create_connection
raise self._reap_last_connection_workflow_error(error)
pika.exceptions.AMQPConnectionError

这是 AMQP_SERVER_URL=amqp://guest:guest@localhost:5672，

我尝试先运行 rabbitmq 容器，然后运行 ​​python 容器来检查它是否有效，但它会引发相同的错误。
