Question

Name:           abcxyz5
Namespace:      diyclientapps
Labels:         <none>
Annotations:        kubectl.kubernetes.io/last-applied-configuration={"apiVersion":"v1","kind":"Service","metadata":{"annotations":{},"name":"abcxyz5","namespace":"diyclientapps"},"spec":{"ports":[{"port":8080,"protocol"...
Selector:       app=abcxyz5
Type:           NodePort
IP:         10.97.214.209
Port:           <unset> 8080/TCP
NodePort:       <unset> 30097/TCP
Endpoints:      <none>
Session Affinity:   None
Events:         <none>

这是我的服务定义：

apiVersion: v1
kind: Service
spec:
  selector:
    app: abcxyz5
  ports:
  - port: 8080
    targetPort: 8123
    protocol: TCP
  type: NodePort
metadata:
  name: abcxyz5

为什么不使用8123的targetPort值？尽管如此，我无法访问此服务：

telnet 192.168.99.100 30097       
Trying 192.168.99.100...
telnet: Unable to connect to remote host: Connection refused

我引用了退回的IP：minikube ip：192.168.99.100。

选择器与任何端点都不匹配。

我修改了它，现在describe service命令显示了这个： Ñ

Annotations:        <none>
Selector:       appId=abcxyz7
Type:           NodePort
IP:         10.99.201.118
Port:           http    8080/TCP
NodePort:       http    30385/TCP
Endpoints:      172.17.0.11:8080

Kubernetes正在使用不正确的端口创建节点端口服务，并且无法访问
