spec.ports[0].name: Required value

这里复现一下这个问题，并记录一下解决方式。

我用kubernetes官网一个最简单的yaml做示例
vi MyApp.yaml

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  selector:
    app: MyApp
  ports:
    - protocol: TCP
      port: 80
      targetPort: 9376

如果用了create或者edit去创建或修改某个资源

~]# kubectl create -f MyApp.yaml              
service/my-service created

或

kubectl edit svc my-service

再用apply就会报错

~]# kubectl apply -f MyApp.yaml       
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
The Service "my-service" is invalid: 
* spec.ports[0].name: Required value
* spec.ports[1].name: Required value

解决方法就是加–force

~]# kubectl apply -f MyApp.yaml --force
service/my-service configured

建议create、edit命令慎用。
