openshift3.11使用nfs-client-provisioner+阿里云NAS提供动态nfs

参考：

https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client

https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client/deploy

在阿里云创建NFS协议的NAS文件系统

创建NAS 挂载点，挂载点地址为：975e54a43a-xxxxx-zhangjiakou.nas.aliyuncs.com:/

准备部署使用的yaml

部署

oc create -f rbac.yaml
oc create -f nfs-client-provisioner.yaml
oc create -f storageclass.yaml

所有需要挂载nfs的宿主机开放selinux pod 挂载nfs权限
