k8s无法删除pv，pvc问题

问题：

在k8s里面创建了pv，pvc删除时报错：error: resource(s) were provided, but no name was specified

解决：

正确的删除顺序：

1.先删除pod

2.再删除pv 

3.在删除pvc

删除pv，pvc命令：

kubectl patch pv pvname -p '{"metadata":{"finalizers":null}}'

kubectl patch pvc pvcname -p '{"metadata":{"finalizers":null}}'

[root@master1 pv]# kubectl get pod
