1. pv概述

PV 持久卷是用插件的形式来实现的。Kubernetes 目前支持以下插件：

cephfs - CephFS volume
csi - 容器存储接口 (CSI)
fc - Fibre Channel (FC) 存储
hostPath - HostPath 卷（仅供单节点测试使用；不适用于多节点集群；请尝试使用 local 卷作为替代）
iscsi - iSCSI (SCSI over IP) 存储
local - 节点上挂载的本地存储设备
nfs - 网络文件系统 (NFS) 存储
rbd - Rados 块设备 (RBD) 卷

以local为例：

apiVersion: v1
kind: PersistentVolume
metadata:name: pv-local
spec :capacity:storage: 2GivolumeMode: FilesystemaccessModes:- ReadWriteOncepersistentVolumeReclaimPolicy: DeletestorageClassName: local-storagelocal:path: /data/localpv # k8s-node-03节点上的目录nodeAffinity:required:nodeSelectorTerms:- matchExpressions:- key: kubernetes.io/hostnameoperator: Invalues :- k8s-node-03

pv资源类型不是通过统一的type='xxx’进行区分的，而是直接使用特定的属性，例如上面的local 就是表示local pv

完整的参数类型如下：
