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}}'

1.停掉pod
[root@master1 pv]# kubectl delete -f nginx-pod.yaml 
service "nginx-service" deleted
deployment.apps "nginx-web" deleted

2.解除pv绑定
[root@master1 pv]# kubectl patch pv pv -p '{"metadata":{"finalizers":null}}'
persistentvolume/pv patched

3.解除pvc绑定
[root@master1 pv]# kubectl patch pvc pvc -p '{"metadata":{"finalizers":null}}'
persistentvolumeclaim/pvc patched

4.删除pv，pvc
[root@master1 pv]# kubectl delete pv pv
persistentvolumeclaim "pv" deleted

[root@master1 pv]# kubectl delete pvc pvc
persistentvolumeclaim "pvc" deleted
