k8s里面存储一直是比较难搞得，之前做的静态存储，写这篇文档记录一下动态存储创建的过程。

使用动态存储的好处是开发者可以更关注自己的开发环境，不用关心后端的资源，还有就是更换存储类型不用做大的改变，只需切换一下storageclassName即可。

根据这篇博客来的！谢谢博主！！！

我把大致上思路分成三步：1.搭建NFS服务器；2.准备NFS动态插件的配置文件；3.创建一个pvc查看测试一下结果。

1.搭建NFS服务器：centos7 下面使用yum安装 ：

yum install nfs-utils

systemctl start nfs

systemctl enable nfs

2.准备nfs插件配置文件：

第一步先测试一下静态存储，测试没有问题了接着往下看动态存储
