k8s中ClusterRoleBindings和RoleBindings，创建自定义角色

RBAC使用标准Kubernetes资源配置，用户可以通过绑定(ClusterRoleBindings和RoleBindings)到一组角色(集群角色和角色)。用户启动时没有权限，必须由管理员明确授予访问权限

k8s中Deployment（nfs-client-provisioner）

1.这个镜像需要下载，配置自己仓库地址image: 10.10.31.205/k8s/nfs-client-provisioner:latest

2.env和volumes的配置信息

k8s中StorageClass

apiVersion: storage.k8s.io/v1kind: StorageClassmetadata: name: szy-cloud-nfs-1provisioner: szycloud/nfs1 # or choose another name, must match deployment's env PROVISIONER_NAME'parameters: archiveOnDelete: "false"

注意：nfs服务配置的文件目录要有操作权限

​​搭建NFS服务 ,并在Kubernetes挂载NFS​​

#NFS服务的配置文件 /etc/exports。 这个文件可能不会存在，需要新建[root@szy-k8s-master /]# cat /etc/exports/nfs/prometheus/data/ 10.10.31.0/24(rw,no_root_squash,no_all_squash,sync)#exports中的配置的内容，需要创建下/nfs/prometheus/data/[root@szy-k8s-master /]# mkdir -p /nfs/prometheus/data/#修改权限[root@szy-k8s-master /]# chmod -R 777 /nfs/prometheus/data/#验证配置的/nfs/prometheus/data/是否正确[root@szy-k8s-master /]# exportfs -r
