#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
