介绍

参考

存储类搭建

1. 首先搭建NFS-SERVER
2. 其次创建NFS-Subdir-External-Provisioner
3. 最后创建NFS StorageClass
   此时存储类就搭建完成

使用

1. 存储类使用，先创建PVC，从存储类动态分配PV
2. 负载再绑定PV使用

正文

简介

1、创建NFS-Subdir-External-Provisioner
1-sep.yaml
2、创建NFS StorageClass
2-sc.yaml

3、创建PVC
3-pvc.yaml

4、负载绑定pv
4-deplozyment.yaml

5、创建service
5-service.yaml

1、 nfs插件
