Question

我一直在尝试创建一个 docker compose 文件来在 swarm 中的不同节点上运行服务。 VerneMQ 的想法是在一个集群内有一个主节点和 N 个（在我的例子中是 2）个副本。

这是目前我的 docker-compose.yml

version: "3.7"
services:
  vmq0:
    image: erlio/docker-vernemq
    environment:
      DOCKER_VERNEMQ_SWARM: 1
      DOCKER_VERNEMQ_ACCEPT_EULA: "yes"
      DOCKER_VERNEMQ_PLUGINS.vmq_passwd: 'off'
      DOCKER_VERNEMQ_ALLOW_ANONYMOUS: 'on'
      DOCKER_NET_INTERFACE: eth0
  vmq:
    image: erlio/docker-vernemq
    depends_on:
      - vmq0
    environment:
      DOCKER_VERNEMQ_SWARM: 1
      DOCKER_VERNEMQ_DISCOVERY_NODE: vmq0
      DOCKER_VERNEMQ_ACCEPT_EULA: "yes"
      DOCKER_VERNEMQ_PLUGINS.vmq_passwd: 'off'
      DOCKER_VERNEMQ_ALLOW_ANONYMOUS: 'on'
      DOCKER_NET_INTERFACE: eth1
    ports:
      - 50005:1883
      - 8080:8080
    deploy:
      replicas: 2

我创建了群。

尝试部署堆栈：

docker stack deploy -c docker-compose.yml  my-vernemq-stack

输出：

Ignoring deprecated options:.

Creating network my-vernemq-stack_default
Creating service my-vernemq-stack_vmq0
Creating service my-vernemq-stack_vmq

主节点输出（两个“从”节点都成功加入）：

13:34:43.340 [info] successfully connected to cluster node 'VerneMQ@10.0.9.4'
13:34:43.454 [info] successfully connected to cluster node 'VerneMQ@10.0.9.3'

我试图获取容器的 IP：

docker inspect my-vernemq-stack_default | grep \"IPv4Address\"

输出：

            "IP": "192.168.1.14"
        }
    ]
}

这些是 IPv4 地址：

"IPv4Address": "10.0.9.7/24",
"IPv4Address": "10.0.9.4/24",
"IPv4Address": "10.0.9.3/24",
"IPv4Address": "10.0.9.5/24",

前三个是容器/节点 IPv4，最后一个是网络的默认端点。

现在，我尝试使用 mosquitto 代理订阅任何节点：

sudo mosquitto_sub -h 10.0.9.7 -p 1883 -t Sample/Topic -d

但是没有任何反应。群内的一切都在工作，我可以使用“docker exec”连接到容器，但我无法发布或订阅代理（我没有得到任何回应）。我做错了什么？

Docker Swarm + VerneMQ（无法从本地主机连接）
