Docker 无法从kubernetes群集访问rabbitmq仪表板

kubernetes群集在两个节点上运行。一个主人，一个工人。。。 编织网是豆荚网

[root@irf-centos1 ~]# kubectl cluster-info
Kubernetes master is running at https://10.8.156.184:6443
KubeDNS is running at https://10.8.156.184:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

在kubernetes吊舱中部署了兔子码头工人图像作为容器

[root@irf-centos1 ~]# kubectl get pods
NAME                        READY   STATUS    RESTARTS   AGE

rabbitmq-86bd97fd9d-n2kgk   1/1     Running   0          51m

以下是服务和部署yaml文件

rabbitmq     NodePort    10.98.204.64   <none>        5672:31111/TCP   55m

当我从web浏览器中点击相同的URL时，什么都没有发生

请建议

注意：此集群是在AZure VM上使用kubeadm部署的。为了进行故障排除，我已经打开了这些虚拟机上的所有入站/出站端口，因此，这不应该是防火墙、端口阻塞问题

我修改了服务文件如下，并重新部署了相同的文件。公共安全局

apiVersion: v1

    - name: ui

      targetPort: 5672
      protocol: TCP
      nodePort: 31111
  selector:
    app: rabbitmq
  type: NodePort

仍然得到相同的错误

[root@irf-centos1 ~]# curl -I http://guest:guest@10.8.156.187:31111/api/users
curl: (56) Recv failure: Connection reset by peer
AMQP    [root@irf-centos1 ~]# curl -I http://guest:guest@10.8.156.187:31112/api/users
curl: (7) Failed connect to 10.8.156.187:31112; Connection refused

对于rabbitmq仪表板/UI，它运行在：

15672

所以服务文件中应该包括端口号：

15672

然后访问仪表板/UI为应用程序创建用户。然后使用此用户

curl

---
apiVersion: v1
kind: Service
metadata:
  name: rabbitmq
  namespace: default
spec:
  ports:
    -
      port: 5672
      targetPort: 5672
      protocol: TCP
      nodePort: 31111
    - 
      protocol: TCP
      port: 15672
      targetPort: 15672
      nodePort: 31112

  selector:
    app: rabbitmqapp
  type: NodePort

或者使用rabitmq的默认用户名和密码

guest

：

curl -I http://guest:guest@10.8.156.187:31112/api/users

部署文件添加容器端口：

      image: "docker.io/rabbitmq:latest"
      imagePullPolicy: Always
      name: rabbitmq
      ports:
        -
          containerPort: 5672
          name: http-port
          containerPort: 15672
          name: ui-port

事实上，使用了错误的docker图像。。。对于rabbitmq dashbaord，docker映像应为docker:management。我改变了，它成功了

以下是更新的服务和部署yaml文件：

          ports:
            -
              containerPort: 15672
              name: http-port
          volumeMounts:
            -
              mountPath: /var/rabbitmqapp_home
              name: rabbitmqapp-home
      volumes:
        -
          emptyDir: {}

请建议。我也修改了服务和部署，然后再次部署。。对于此命令，

kubectl get services
