RabbitMq在docker中运行时拒绝连接

Question

我的docker撰写文件如下所示：

version: '2'

services:
  explore:
    image: explore
    build:
      context: ./Explore
      dockerfile: VsDockerfile
    environment:
      - "ElasticUrl=http://localhost:9200"
      - "RabbitMq/Host=localhost"
      - "RabbitMq/Username=guest"
      - "RabbitMq/Password=guest"
    networks:
      - localnet

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:5.4.3
    container_name: elasticsearch
    environment:
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ports:
      - 9200:9200
    volumes:
      - ./esdata:/usr/share/elasticsearch/data
    networks:
      - localnet

  rabbit:
    image: rabbitmq:3.6.7-management
    hostname: rabbit
    ports:
      - 15672:15672
      - 5672:5672
    networks:
      - localnet

networks:
  localnet:
    external:
      name: localnet

如果我在浏览器中键入http://localhost:15672，我将获得Rabbitmq界面，但是如果我试图像这样从我的探索项目连接：

public SqlToRabbitProcessor(SqlToRabbitRepository sqlToRabbitRepository)
{
    _sqlToRabbitRepository = sqlToRabbitRepository;

    var factory = new ConnectionFactory
    {
        HostName = Environment.GetEnvironmentVariable("RabbitMq/Host"),
        UserName = Environment.GetEnvironmentVariable("RabbitMq/Username"),
        Password = Environment.GetEnvironmentVariable("RabbitMq/Password")
    };

    var rabbit = factory.CreateConnection();
    channel = rabbit.CreateModel();
}

然后它在队伍中断了

var rabbit = factory.CreateConnection();

错误是说

ExtendedSocketException:连接被拒绝127.0。0.1:5672html" target="_blank">系统。网插座。插座EndConnect（IAsyncResult异步结果）

ConnectFailureException:连接失败RabbitMQ。客户最终解决了紧张局势。SelectOne（IEndpointResolver解析器、Func选择器）

BrokerRunReachableException:指定的终结点都无法访问RabbitMQ。客户连接工厂。CreateConnection（IEndpointResolver endpointResolver，字符串clientProvidedName）

Answer 1

按照这篇文章的说明去做。

只是为了让偶然发现这个问题的人受益。--link功能现在被认为是遗留的，是docker不推荐的主要候选功能。最简单的方法是用

depends_on：为了做到这一点，建议首先创建一个这样的网络”

docker network create <network_name>

然后使用docker compose up生成相互绑定的服务。看看下面的例子，我将我的spring boot应用程序绑定到rabbit mq。你可以从这里克隆我的回购协议

version: "3.1"
services:
  rabbitmq-container:
    image: rabbitmq:3.5.3-management
    hostname: rabbitmq-container
    ports:
      - 5673:5673
      - 5672:5672
      - 15672:15672
    networks:
      - resolute

  resolute-container:
    build: .
    ports:
      - 8080:8080
    environment:
      - spring_rabbitmq_host=rabbitmq-container
      - spring_rabbitmq_port=5672
      - spring_rabbitmq_username=guest
      - spring_rabbitmq_password=guest
      - resolute_rabbitmq_publishQueueName=resolute-run-request
      - resolute_rabbitmq_exchange=resolute
    depends_on:
      - rabbitmq-container
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    networks:
      - resolute

networks:
  resolute:
    external:
      name: resolute

Answer 2

我和docker compose也有同样的问题。

我用主机名解决了这个问题：

  rabbit:
    hostname: rabbit
    command: sh -c "rabbitmq-plugins enable rabbitmq_management; rabbitmq-server"
    image: rabbitmq
    environment:
      RABBITMQ_DEFAULT_USER: admin
      RABBITMQ_DEFAULT_PASS: admin
    ports:
        - 5672:5672
        - 15672:15672

Answer 3

正如我在问题下的评论所指出的，这是因为web应用程序部分中定义的“localhost”是容器localhost，而不是docker主机。。

只是需要改变

- "ElasticUrl=http://localhost:9200"
- "RabbitMq/Host=localhost"

到

- "ElasticUrl=http://elasticsearch:9200"
- "RabbitMq/Host=rabbit"
