一、认识​

二、静态供应​

2.1 编写 PV 配置文件​

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-demo
spec:
  storageClassName: test-pv
  capacity:
    storage: 2Gi
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Recycle
  nfs:
    server: k8s-master
    path: /mnt/nfs_share

2.2 创建 PV 存储资源​

kubectl apply -f test-pv.yaml

2.3 编写 PVC 配置文件​

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-demo
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 500Mi

2.4 创建 PVC 用户请求​

kubectl apply -f test-pvc.yaml

2.5 验证 PVC PV 状态​

kubectl get pv pv-demo 

kubectl get pvc pvc-demo

三、动态供应​

3.1 编写 StorageClass 配置​

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: aws-ebs-sc
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  fsType: ext4
reclaimPolicy: Retain
allowVolumeExpansion: true
volumeBindingMode: WaitForFirstConsumer

3.2 创建 StorageClass 应用​

3.3 编写 PVC 配置文件​

在创建 PVC 时，通过指定 storageClassName 绑定到特定的 StorageClass：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: dynamic-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: aws-ebs-sc

3.4 创建 PVC 动态请求​
