每个 StorageClass 都有一个制备器（Provisioner），用来决定使用哪个卷插件制备 PV。

nfs-storage-class.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: managed-nfs-storage
  namespace: kube-system
provisioner: fuseim.pri/ifs # 外部制备器提供者，编写为提供者的名称
parameters:
  archiveOnDelete: "false" # 是否存档，false 表示不存档，会删除 oldPath 下面的数据，true 表示存档，会重命名路径
reclaimPolicy: Retain # 回收策略，默认为 Delete 可以配置为 Retain
volumeBindingMode: Immediate # 默认为 Immediate，表示创建 PVC 立即进行绑定，只有 azuredisk 和 AWSelasticblockstore 支持其他值

nfs-provisioner-rbac.yaml

首先创建rabc

[root@k8s-master storageclass]# kubectl apply -f nfs-provisioner-rbac.yaml 
serviceaccount/nfs-client-provisioner created
clusterrole.rbac.authorization.k8s.io/nfs-client-provisioner-runner created
clusterrolebinding.rbac.authorization.k8s.io/run-nfs-client-provisioner created
role.rbac.authorization.k8s.io/leader-locking-nfs-client-provisioner created
rolebinding.rbac.authorization.k8s.io/leader-locking-nfs-client-provisioner created

创建deployment

1 2	`[root@k8s-master storageclass]# kubectl apply -f nfs-provisioner-deployment.yaml deployment.apps/nfs-client-provisioner created`

创建storageClass

1 2	`[root@k8s-master storageclass]# kubectl apply -f nfs-storage-class.yaml storageclass.storage.k8s.io/managed-nfs-storage created`

PS：

这里创建时出现了问题，将上面所有namespace改为default再重新apply一遍就好了

在pull quay.io/external_storage/nfs-client-provisioner时出现了错误，在我找解决方法时它自己好了
