我已经通过RabbitIP部署了ClusterIP服务。

部署:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: rabbit-mq
  name: rabbit-mq
spec:
  replicas: 1
  selector:
    matchLabels:
      app: rabbit-mq
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
         app: rabbit-mq
    spec:
      containers:
      - image: rabbitmq:3.6.1-management
        name: rabbit-mq
        ports:        
        - containerPort: 5672
        volumeMounts:
        - mountPath: /etc/rabbitmq
          name: rabbit-mq-data
      restartPolicy: Always
      hostname: rabbit-mq
      volumes:
      - name: rabbit-mq-data
        persistentVolumeClaim:
          claimName: rabbit-mq-data

服务:

apiVersion: v1
kind: Service
metadata:
  name: rabbit-mq-service
  labels:
    app: rabbit-mq
  namespace: default
spec:
  type: ClusterIP
  ports:
  - port: 5672    
  selector:
   app: rabbit-mq

正如我对其他服务进行的测试以及在文档中所述,ClusterIP服务对于群集内的所有pod和节点都应该可见。 我需要RabbitMQ服务只能在集群内部访问。 正如我定义的5672端口一样,它也用于targetPort。

我有.NET Core应用程序通过以下连接字符串连接到服务: amqp://user:password@10.100.10.10:5672/

kubectl get svc rabbit-mq-service NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE rabbit-mq-service ClusterIP 10.100.10.10 <none> 5672/TCP 3h7m

当我尝试连接RabbitMQ时,出现错误:

Unhandled Exception: RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---> System.AggregateException: One or more errors occurred. (Connection failed) ---> RabbitMQ.Client.Exceptions.ConnectFailureException: Connection failed ---> System.TimeoutException: The operation has timed out.

我是否误解了ClusterIP服务的工作原理?

1 个答案:

答案 0 :(得分:1)

尝试一下:

apiVersion: v1
kind: Service
metadata:
  name: rabbit-mq-service
  labels:
    app: rabbit-mq
  namespace: default
spec:
  type: ClusterIP
  clusterIP: None
  ports:
  - port: 5672    
  selector:
   app: rabbit-mq

amqp://user:password@rabbit-mq-service:5672/
