無法連接到ClusterIP服務

Question

我已經使用RabbitIP部署了ClusterIP服務。

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

服務：

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

正如我對其他服務進行的測試以及在文檔中所說的那樣，ClusterIP服務對於群集內的所有Pod和節點都應該可見。 我需要RabbitMQ服務只能在集群內部訪問。 正如我定義的端口5672一樣，它也用於targetPort。

我有.NET Core應用程序使用以下連接字符串連接到服務： 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

當我嘗試連接到RabbitMQ時，出現錯誤：

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.

我是否誤解了ClusterIP服務的工作方式？

Answer 1

嘗試這個：

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

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