如何 docker-compose ThingsBoard + RabbitMQ？

Question

按照ThingsBoard 的教程，他们似乎建议对 RabbitMQ 使用本地桌面安装，并使用一些引用它的变量运行 docker-compose。

我个人不喜欢直接在我的 PC 上安装此类应用程序，而是更喜欢它们的 docker 实例。

我希望尝试通过 Docker 同步我的 docker ThingsBoard 和 RabbitMQ。

这是我目前使用的 docker-compose.yml 文件：

version: '2.2'
services:
  mytb:
    privileged: true
    restart: always
    depends_on: 
      - rabbitmq
    image: "thingsboard/tb-postgres"
    ports:
      - "9091:9090"
      - "1883:1883"
      - "7070:7070"
      - "5683-5688:5683-5688/udp"
    environment:
      TB_QUEUE_TYPE: rabbitmq
      TB_QUEUE_RABBIT_MQ_USERNAME: test
      TB_QUEUE_RABBIT_MQ_PASSWORD: test123369
      TB_QUEUE_RABBIT_MQ_HOST: localhost
      TB_QUEUE_RABBIT_MQ_PORT: 5672
    volumes:
      - ./mytb-data:/data
      - ./mytb-logs:/var/log/thingsboard

  rabbitmq:
    image: rabbitmq:3-management
    environment:
      # RABBITMQ_ERLANG_COOKIE: 'asdfjasifasjfawfjisfjasifjioasjfoiasj'
      RABBITMQ_DEFAULT_USER: test
      RABBITMQ_DEFAULT_PASS: test123369
    volumes:
     - ./rmq-test/db-data:/var/lib/rabbitmq
    ports:
      - 5672:5672
      - 15672:15672

我不断让 ThigsBoard 服务器重新启动，错误提示它无法连接到 RabbitMQ。

我尝试更改行： TB_QUEUE_RABBIT_MQ_HOST: localhost为TB_QUEUE_RABBIT_MQ_HOST: rabbitmq或使用分配给 docker 容器的 ip 地址，但我不断在循环中收到此错误：

别客气 ：）

默认情况下，docker 连接内部网络中的服务。 要引用其他服务，您需要使用服务名称（或别名...），localhost 将不起作用。

发布的第二个问题与 rabbitmq 连接无关，您的 mytb_1 容器无法访问您的数据卷映射。 该服务需要有足够的权限来写入映射的目录

version: '2.2'
services:
  mytb:
    privileged: true
    restart: always
    depends_on: 
      - rabbitmq

      - "9091:9090"
      - "1883:1883"
      - "7070:7070"
      - "5683-5688:5683-5688/udp"
    environment:
      TB_QUEUE_TYPE: rabbitmq
      TB_QUEUE_RABBIT_MQ_USERNAME: test
      TB_QUEUE_RABBIT_MQ_PASSWORD: test123369
      # Use the rabbitmq service name as a host instead of localhost
      TB_QUEUE_RABBIT_MQ_HOST: rabbitmq 
      TB_QUEUE_RABBIT_MQ_PORT: 5672
    volumes:        
      - ./.mytb-data:/data
      - ./.mytb-logs:/var/log/thingsboard
      # make sure that the service has sufficient rights to
      # write to the mapped directories
