背景说明

通过kubectl进行获取资源对象例如pod、pv时可能需要自定义输出字段，比如默认情况下

  1. student@master01:~$ kubectl get pod
  2. NAME                            READY   STATUS    RESTARTS       AGE
  3. 11-factor-app                   1/1     Running   6 (23d ago)    72d
  4. foo                             1/1     Running   6 (23d ago)    72d
  5. front-end-94f5bf8fb-hxg4p       1/1     Running   6 (23d ago)    72d
  6. podname1                        1/1     Running   1 (112m ago)   113m
  7. podname2                        1/1     Running   1 (107m ago)   112m
  8. presentation-5649f596b9-jxfnn   1/1     Running   6 (23d ago)    72d
  9. student@master01:~$

假如只想得到NAME时则可以使用一定的指令进行配置
