# 1. 搭建nfs服务器
nfs搭建过程查看linux中的nfs文档
# 2. 创建ServiceAccount
Kubernetes (opens new window) 集群大部分是基于 RBAC 的权限控制，所以创建一个一定权限的 ServiceAccount 与后面要创建的 “NFS Provisioner” 绑定，赋予一定的权限。
vim nfs-rbac.yaml
# 内容
kind: ServiceAccount
apiVersion: v1
metadata:
name: nfs-client-provisioner
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: nfs-client-provisioner-runner

- apiGroups: [""]
resources: ["persistentvolumes"]
