Docker

Question

我已经使用 this docker 图像在我的开发机器上设置了 RabbitMQ 服务器。

我使用下面的命令来设置我的容器

docker run -d --name my-rabbit -p 5672:15672 rabbitmq:3-management

下面是dockerps命令输出

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a40704b7f3a4 rabbitmq:3-management "docker-entrypoint.s…" 13 minutes ago Up 12 minutes 4369/tcp, 5671-5672/tcp, 15671/tcp, 25672/tcp, 0.0.0.0:5672->15672/tcp my-rabbit

可在 http://localhost:5672 访问管理控制台，我可以使用默认用户名和密码 ( guest/guest )

登录

下面是我的 .Net Core 代码

public RabbitMQMnager()
        {
            var factory = new ConnectionFactory();
            factory.Port = 5672;
            Uri uri = new Uri("amqp://guest:guest@localhost:5672/");

            var connection = factory.CreateConnection();

            //Below are values of different connection string parameters
            factory.HostName = "localhost";
            factory.UserName = "guest";
            factory.Password = "guest";
            factory.VirtualHost = "/";
            factory.Port = 5672;

            var channel = connection.CreateModel(); //<- Exception here
        }

执行上述代码后，出现以下异常。

RabbitMQ.Client.Exceptions.BrokerUnreachableException: 'None of the specified endpoints were reachable'

堆栈跟踪

This exception was originally thrown at this call stack: RabbitMQ.Client.Framing.Impl.Connection.StartAndTune() RabbitMQ.Client.Framing.Impl.Connection.Open(bool) RabbitMQ.Client.Framing.Impl.Connection.Connection(RabbitMQ.Client.IConnectionFactory, bool, RabbitMQ.Client.Impl.IFrameHandler, string) RabbitMQ.Client.Framing.Impl.AutorecoveringConnection.Init(RabbitMQ.Client.Impl.IFrameHandler) RabbitMQ.Client.Framing.Impl.AutorecoveringConnection.Init(RabbitMQ.Client.IEndpointResolver) RabbitMQ.Client.ConnectionFactory.CreateConnection(RabbitMQ.Client.IEndpointResolver, string)

我发现了类似的问题，但提到的解决方案对我来说还不够。看起来它与 docker 和 docker.

创建的网络有关

根据@ThisIsNoZaku 的回答，公开额外的端口解决了我的问题。

docker run -d --hostname my-rabbit --name my-rabbit -p 15672:15672 -p  5672:5672 rabbitmq:3-management

用于使用 AMQP 客户端连接到 RabbitMQ 实例并连接到管理控制台的端口 UI（容器中的 15762，您已将其映射到 5762在主机上）是不同的。当应用程序尝试将 AMQP 客户端指向管理端口时，失败 because it's not supported:

The management UI can be accessed using a Web browser

...

Note that the UI and HTTP API port — typically 15672 — does not support AMQP 0-9-1, AMQP 1.0, STOMP or MQTT connections. Separate ports should be used by those clients.

您的 RabbitMQ 实例应该公开，并且您的客户端连接到 correct ports for AMQP:

5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS
