动态存储类

1. 创建 RBAC 资源
   保存为 nfs-provisioner-rbac.yaml：

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-client-provisioner
  namespace: default
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nfs-client-provisioner-runner
rules:
  - apiGroups: [""]
    resources: ["persistentvolumes"]
    verbs: ["get", "list", "watch", "create", "delete"]
  - apiGroups: [""]
    resources: ["persistentvolumeclaims"]
    verbs: ["get", "list", "watch", "update"]
  - apiGroups: ["storage.k8s.io"]
    resources: ["storageclasses"]
    verbs: ["get", "list", "watch"]
  - apiGroups: [""]
    resources: ["events"]
    verbs: ["create", "update", "patch"]
  - apiGroups: [""]
    resources: ["persistentvolumeclaims/status"]
    verbs: ["update"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: run-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: default
roleRef:
  kind: ClusterRole
  name: nfs-client-provisioner-runner
  apiGroup: rbac.authorization.k8s.io

2. 创建 Deployment
   保存为 nfs-provisioner-deployment.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-client-provisioner
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nfs-client-provisioner
  template:
    metadata:
      labels:
        app: nfs-client-provisioner
    spec:
      serviceAccountName: nfs-client-provisioner
      containers:
        - name: nfs-client-provisioner
          image: k8s.gcr.io/sig-storage/nfs-subdir-external-provisioner:v4.0.2
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: nfs.io/nfs
            - name: NFS_SERVER
              value: 192.168.1.100 # 替换为你的 NFS 服务器地址
            - name: NFS_PATH
              value: /exported/path # 替换为你的 NFS 共享路径
      volumes:
        - name: nfs-client-root
          nfs:
            server: 192.168.1.100 # 替换为你的 NFS 服务器地址
            path: /exported/path   # 替换为你的 NFS 共享路径

3. 创建 StorageClass
   保存为 nfs-storageclass.yaml：

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-storage-class
provisioner: nfs.io/nfs
parameters:
  archiveOnDelete: "false"  # 删除 PVC 时是否保留数据

4.创建一个 PVC 测试： 保存以下内容为 test-pvc.yaml：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: test-pvc
spec:
  storageClassName: nfs-storage-class
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi
