//NFS使用PV和PVC

1、配置nfs存储

2、定义PV 

 实现 下图的pv和pvc测试

 pv的定义

这里定义5个PV，并且定义挂载的路径以及访问模式，还有PV划分的大小

vim /pv.yamlapiVersion: v1
kind: PersistentVolume
metadata:name: pv001
spec:capacity:storage: 1GiaccessModes:- ReadWriteOnce- ReadWriteMany#persistentVolumeReclaimPolicy: Recycle#storageClassName: slownfs:path: /opt/k8s/v1server: 192.168.47.60
---
apiVersion: v1
kind: PersistentVolume
metadata:name: pv002
spec:capacity:storage: 2GiaccessModes:- ReadWriteOnce#persistentVolumeReclaimPolicy: Recycle#storageClassName: slownfs:path: /opt/k8s/v2server: 192.168.47.60

apiVersion: v1
kind: PersistentVolume
metadata:name: pv003

spec:capacity:storage: 5GiaccessModes:- ReadWriteOnce- ReadWriteMany#persistentVolumeReclaimPolicy: Recycle#storageClassName: slownfs:path: /opt/k8s/v5server: 192.168.47.60

创建使用静态pv 

 定义PVC

这里定义了pvc的访问模式为多路读写，该访问模式必须在前面pv定义的访问模式之中。定义PVC申请的大小为2Gi，此时PVC会自动去匹配多路读写且大小为2Gi的PV，匹配成功获取PVC的状态即为Bound

 

 

 

 

测试访问

在存储服务器上创建index.html，并写入数据，通过访问Pod进行查看，可以获取到相应的页面

 

 

 

 实现 NFS 的动态 PV 创建

配置nfs存储

 

创建存储卷插件的pod 

 

 创建 StorageClass，负责建立 PVC 并调用 NFS provisioner 进行预定的工作，并让 PV 与 PVC 建立关联
