K8S基于NFS来动态创建PV【亲测可用】

博主的kubernetes的版本是1.24.0，- --feature-gates=RemoveSelfLink=false 默认是true，且不支持修改为false，否则apiserver会启动失败！
最终解决方案是将provisioner的容器镜像更新为最新版本，如 registry.cn-beijing.aliyuncs.com/mydlq/nfs-subdir-external-provisioner:v4.0.0。

# 安装 nfs-utils, rpcbind
yum install -y nfs-utils rpcbind
# 启动服务
systemctl enable nfs
systemctl start nfs
# 创建挂载目录
mkdir -pv /data/nfs
## 配置目录参数
echo "/data/nfs 192.168.81.128/24(rw,sync,no_root_squash,no_all_squash)" > /etc/exports
# 重启NFS服务
systemctl restart nfs
# 验证
showmount -e 127.0.0.1

# 安装 nfs-utils
yum install -y nfs-utils
# 验证
showmount -e 192.168.81.128
