Kubernetes：打开Pod之间的不同服务连接

Question

我已在 pod 存储上创建了两个服务连接（节点端口），用于通过端口 8885 和 8881 与 pod 应用进行通信。我了解到我需要在应用部署上使用与我指定的节点端口相同的名称的 matchselect。您能否向我展示一个实际示例，其中 pod 应用可以通过端口 8881 和 8885 访问 pod 存储？

我已经在应用程序容器（docker）中测试了 telnet demo-storage-manageport 8885 和 demo-storage-nodeport 8881，但是它不起作用。

服务连接：

apiVersion: v1
kind: Service
metadata:
  name: demo-storage-nodeport
  namespace: demo-customer
  labels:
    run: demo-storage
spec:
  type: NodePort
  ports:
  - port: 8881
    targetPort: 8881
    protocol: TCP
    name: tomcat-http
  selector:
    app: demo-app
---
apiVersion: v1
kind: Service

  - port: 8885
    targetPort: 8885
