安装NFS扩展

#添加helm源
helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner

#创建个namespace(可选，主要是为了查看资源方便)
kubectl create ns nfs-sc-default

#使用helm安装(10.1.129.86为NFS地址，/home/data/nfs-share/为共享的目录)
helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
    --set storageClass.name=nfs-sc-default    #指定sc的名字
    --set nfs.server=10.10.10.99 \                    #指定nfs地址
    --set nfs.path=/home/data/nfs-share/ \                    #指定nfs的共享目录
    --set storageClass.defaultClass=true \    #指定为默认sc
    -n default                                                #指定命名空间

#查看创建的sc

kubectl get sc

第二种、
#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 '#|^$'
