如图状态一直为ContainerCreating。

先用命令kubectl describe pod nfs-client-xxxx -n xxxx检查pod

原因是挂载的节点必须安装nfs的客户端，否则不适配、
执行命令安装nfs就好了

yum install nfs-utils

然后配置命令

echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports
mkdir -p /nfs/data
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server
exportfs -r

接着用命令exportfs 检查配置是否生效，显示/nfs/data <world>即为成功
