介绍：

目前动态生成NAS存储卷的实现：在一个已有文件系统上，自动生成子文件系统（子目录），并生成目标存储卷（PV）；

生成的PV名字为：pvc-${pv-uid}

镜像介绍：

registry.cn-hangzhou.aliyuncs.com/acs/alicloud-nas-controller:v3.1.0-k8s1.11

部署：

部署前要先创建一个NAS文件系统，并添加挂载点。注意：挂载点需要和集群处于同一个VPC内部。

部署模板中，创建Storageclass的时候可以定义reclaimPolicy类型，可以为Retain或者Delete；

根据自己NAS挂载点修改NFS_SERVER、server的值；
