一、部署ceph snapshot控制器

### --- snapshot控制器说明

~~~     k8s 1.19版本以上需要单独安装snapshot控制器，才能完成pvc的快照功能，
~~~     所以在此提前安装下，如果是1.19以下版本，不需要单独安装；
~~~     snapshot控制器的部署在集群安装时的k8s-ha-install项目中，需要切换到1.20.x分支：

二、安装ceph snapshot控制器

### --- 切换到k8s安装目录下
[root@k8s-master01 ceph]# cd /root/k8s-ha-install/

### --- 切换到1.20.x分支
[root@k8s-master01 k8s-ha-install]# git checkout manual-installation-v1.20.x

### --- 创建snapshot controller

[root@k8s-master01 k8s-ha-install]# kubectl create -f snapshotter/ -n kube-system
serviceaccount/snapshot-controller created
clusterrole.rbac.authorization.k8s.io/snapshot-controller-runner created
clusterrolebinding.rbac.authorization.k8s.io/snapshot-controller-role created
role.rbac.authorization.k8s.io/snapshot-controller-leaderelection created
rolebinding.rbac.authorization.k8s.io/snapshot-controller-leaderelection created
statefulset.apps/snapshot-controller created
service/snapshot-controller created
customresourcedefinition.apiextensions.k8s.io/volumesnapshotclasses.snapshot.storage.k8s.io created
customresourcedefinition.apiextensions.k8s.io/volumesnapshotcontents.snapshot.storage.k8s.io created

### --- 查看创建的snapshot controller
~~~     具体文档：https://rook.io/docs/rook/v1.5/ceph-csi-snapshot.html    

[root@k8s-master01 k8s-ha-install]# kubectl  get po -n kube-system -l app=snapshot-controller -owide
NAME                    READY   STATUS    RESTARTS   AGE   IP              NODE         NOMINATED NODE   READINESS GATES
