未处理的异常。RabbitMQ.Client.Exceptions.BrokerUnreachableException:没有一个指定的端点是可访问的。

Question

我已经在我的笔记本电脑上设置了RabbitMQ服务器，使用这个码头映像。

https://hub.docker.com/_/rabbitmq

和命令：docker run -d --hostname rabbit-release --name rabbit-releaset -p 15672:15672 -p 5672:5672 rabbitmq:3-management

和背景：

"rabbitMq": {
    "namespace": "common",
    "retries": 3,
    "retryInterval": 2,
    "username": "guest",
    "password": "guest",
    "virtualHost": "/",
    "port": 5672,
    "hostnames": [
      "rabbit-release"
    ],
    "requestTimeout": "00:00:10",
    "publishConfirmTimeout": "00:00:01",
    "recoveryInterval": "00:00:10",
    "persistentDeliveryMode": true,
    "autoCloseConnection": true,
    "automaticRecovery": true,
    "topologyRecovery": true,
    "exchange": {
      "durable": true,
      "autoDelete": false,
      "type": "Topic"
    },
    "queue": {
      "autoDelete": false,
      "durable": true,
      "exclusive": false
    }
  },

这是已退出的容器的日志：

如果在主机中运行客户端代码，则--hostname停靠器选项没有任何效果，因此您需要在客户端代码中使用localhost而不是rabbit-release。
