Question

我试图做一些非常简单的事情并且它不起作用。我必须做一些愚蠢的事情，但我无法看到它。我希望有人可以......

当我在本地docker上运行rabbitmq:latest Docker镜像时，我可以成功连接到它：

docker run -p 5672:5672 -d rabbitmq
telnet <dockerMachineIp> 5672
Trying x.y.z.w...
Connected to x.y.z.w.

现在我将图像部署到k8s：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  labels:
    run: rabbitmq
  name: rabbitmq
  namespace: uat
spec:
  replicas: 1
  selector:
    matchLabels:
      env: uat
      run: rabbitmq
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
    type: RollingUpdate
  template:
    metadata:
      creationTimestamp: null
      labels:
        env: uat
        run: rabbitmq
    spec:
      containers:
      - image: rabbitmq
        imagePullPolicy: Always
        name: rabbitmq
        ports:
        - containerPort: 5672
          protocol: TCP
        readinessProbe:
          failureThreshold: 3
          tcpSocket:
            port: 5672
          initialDelaySeconds: 15
          periodSeconds: 10
          successThreshold: 1
          timeoutSeconds: 1
        livenessProbe:
          failureThreshold: 3
          tcpSocket:
            port: 5672
          initialDelaySeconds: 15
          periodSeconds: 10
          successThreshold: 1
          timeoutSeconds: 1
        resources:
          limits:
            cpu: 100m
            memory: 150Mi
          requests:
            cpu: 100m
            memory: 150Mi
        terminationMessagePath: /dev/termination-log
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      securityContext: {}
      terminationGracePeriodSeconds: 30
status:
  availableReplicas: 1
  observedGeneration: 2
  replicas: 1
  updatedReplicas: 1

我为它创建了一个服务：

apiVersion: v1
kind: Service
metadata:
  name: rabbitmq
  namespace: uat
spec:
  ports:
  - name: tcp5672
    port: 5672
    protocol: TCP
    targetPort: 5672
  selector:
    run: rabbitmq
  sessionAffinity: None
  type: ClusterIP
status:
  loadBalancer: {}

图像已成功部署：

2016-08-16T06:08:15.903787400Z =INFO REPORT==== 16-Aug-2016::06:08:15 ===

2016-08-16T06:11:00.901609310Z

但在此之后我尝试连接到tcp://rabbitmq:5672的其他应用程序会收到Connection Refused。当我自己测试时：

kubectl run --namespace uat -i --tty busybox --image=busybox --restart=Never -- sh
/ # telnet rabbitmq 5672
Connection closed by foreign host

在rabbitmq日志中我可以看到：

2016-08-16T07:38:48.465296167Z =INFO REPORT==== 16-Aug-2016::07:38:48 ===

2016-08-16T07:38:48.465420105Z {handshake_timeout,handshake}

我在这里做的很简单，我不知道我错过了什么。

修改

我把这个问题留在了一边，因为我没有时间研究它。几个星期后，当我再次尝试时，它才开始工作。我没有更改k8s的版本或对基础架构进行任何更改。我怕我不知道发生了什么

Answer 1

5672是无法使用HTTP访问AMQP端口。

管理UI使用端口15672，但您已启用它：

rabbitmq-plugins enable rabbitmq_management

请参阅此https://www.rabbitmq.com/management.html

然后你可以使用：http://server-name:15672/

在Kubernetes集群中的Rabbitmq
