1、先删除pod2、再删除对应的deployment否则只是删除pod是不管用的，还会看到pod，因为deployment.yaml文件中定义了副本数量

实例如下：

删除pod

[root@test2 ~]# kubectl get pod -n jenkins
NAME READY STATUS RESTARTS AGE
jenkins2-8698b5449c-grbdm 1/1 Running 0 8s
[root@test2 ~]# kubectl delete pod jenkins2-8698b5449c-grbdm -n jenkins
pod “jenkins2-8698b5449c-grbdm” deleted

查看pod仍然存储

[root@test2 ~]# kubectl get pod -n jenkins
NAME READY STATUS RESTARTS AGE
jenkins2-8698b5449c-dbqqb 1/1 Running 0 8s
[root@test2 ~]#

删除deployment

[root@test2 ~]# kubectl get deployment -n jenkins
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
jenkins2 1 1 1 1 17h
[root@test2 ~]# kubectl delete deployment jenkins2 -n jenkins

再次查看pod消失

deployment.extensions “jenkins2” deleted
[root@test2 ~]# kubectl get deployment -n jenkins
No resources found.
[root@test2 ~]#
[root@test2 ~]# kubectl get pod -n jenkins
No resources found.
