Question

我根据以下文章启动了RabbitMQ容器：https://docs.docker.com/samples/library/rabbitmq使用包含管理工具的图像

docker run -d --hostname my-rabbit --name some-rabbit -p 8080:15672 rabbitmq:3-management

docker container ls --all
CONTAINER ID        IMAGE                   COMMAND                  CREATED             STATUS              PORTS
         NAMES
8a42bb749074        rabbitmq:3-management   "docker-entrypoint.s…"   8 hours ago         Up 8 hours          4369/tcp, 5671-5672/tcp, 15671/tcp, 25672/tcp, 0.0.0.0:8080->15672/tcp   some-rabbit

我可以通过http://localhost:8080

访问管理工具

然后我创建了that article之后最基本的C＃项目，以与我的RabbitMQ本地实例进行通信：

using System.Globalization;
using RabbitMQ.Client;

namespace RabbitCSharp
{
    public static class Program
    {
        public static void Main(params string[] args)
        {
            var factory = new ConnectionFactory
            {
                HostName = "localhost"
            };
            using (var connection = factory.CreateConnection())
            {
                using (var channel = connection.CreateModel())
                {
                }
            }
        }
    }
}

但不幸的是出现了以下错误：

Unhandled Exception: RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---> System.AggregateException

Process finished with exit code -532,462,766.

不太确定为什么RabbitClient无法通过127.0.0.1:5672

有什么主意吗？

Answer 1

似乎我的容器端口5672没有映射到本地端口5672。

我刚刚创建了另一个包含端口映射的容器，如this answer所示：

docker stop some-rabbit
docker commit some-rabbit some-rabbit-right
docker run -p 5672:5672 -p 8080:15672 -td some-rabbit-right

或者直接运行新实例：

docker run -d --hostname my-rabbit --name some-rabbit -p 5672:5672 -p 8080:15672 rabbitmq:3-management

在C＃程序中（使用RabbitMQ.Client）无法连接到以Docker启动的RabbitMQ
