需要使用NFS创建动态pv，之前查到的都是这个https://github.com/kubernetes-retired/external-storage/tree/master/nfs-client，后来实验了不可以，是因为版本更新了，插件的项目换为https://github.com/helm/charts/tree/master/stable/nfs-client-provisioner了，特此记录

k8s版本： v1.23.1

1. 准备：

   • 搭建好NFS服务；
   • 安装好helm；

2. 安装：

   #添加helm源
   helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner
   
   #直接安装(10.1.129.86为NFS地址，/data/nfs-ops为共享的目录)
   helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
       --set nfs.server=10.1.129.86 \
       --set nfs.path=/data/nfs-ops \
       -n kube-ops (可以选择安装的namespace)
   
   #查看创建的sc
   kubectl get sc -n kube-ops
   

   如果想改的参数更多些，可以下载chart改values.yaml

   #下载chart
   helm pull nfs-subdir-external-provisioner/nfs-subdir-external-provisioner
   
   #解压后可以看到values.yaml
   cat values.yaml | egrep -v '#|^$'
