K8s 部署 StorageClass（基于NFS）

1 创建部署的yaml文件

 

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-client-provisioner
  namespace: kube-system

---

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: ["list", "watch", "create", "update", "patch"]
  - apiGroups: [""]
    resources: ["endpoints"]
    verbs: ["get", "list", "watch", "create", "update", "patch"]

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: run-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: kube-system 
roleRef:
  kind: ClusterRole
  name: nfs-client-provisioner-runner
  apiGroup: rbac.authorization.k8s.io

---

kind: Deployment
apiVersion: apps/v1
metadata:
  name: nfs-provisioner-01
  namespace: kube-system
spec:
  replicas: 1
  strategy:
    type: Recreate
  selector:
    matchLabels:
      app: nfs-provisioner-01
  template:
    metadata:
      labels:
        app: nfs-provisioner-01
    spec:
      serviceAccountName: nfs-client-provisioner
      containers:
        - name: nfs-client-provisioner
          image: registry.cn-hangzhou.aliyuncs.com/navy-wang/nfs-subdir-external-provisioner:v4.0.2
          imagePullPolicy: IfNotPresent
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: nfs-provisioner-01  # 此处供应者名字供storageclass调用
            - name: NFS_SERVER
              value: 192.168.0.4   # 填入NFS的地址
            - name: NFS_PATH
              value: /volume1/nfs-hdd-k8s   # 填入NFS挂载的目录
      volumes:
        - name: nfs-client-root
          nfs:
            server: 192.168.0.4   # 填入NFS的地址
            path: /volume1/nfs-hdd-k8s   # 填入NFS挂载的目录

---

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: sc-nfs-hdd
provisioner: nfs-provisioner-01
# Supported policies: Delete、 Retain ， default is Delete
reclaimPolicy: Retain

2 部署yaml

kc apply -f /root/yaml/storageclass/storageclass-nfs-hdd.yaml # kc是我设置的kubectl的别名

3 查看pod是否启动成功

 4 创建pvc

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc1
  namespace: dev
spec:
  storageClassName: sc-nfs-hdd
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 10Mi

5 查看pvc、pv是否创建成功

 6 NFS服务器上查看pv是否挂载成功

 7 部署Pod验证

7.1 部署Pod

apiVersion: v1
kind: Pod
metadata:
  name: nginx-pvc
  namespace: dev
spec:
  containers:
  - name: nginx
    image: nginx
    volumeMounts:
    - name: html-path
      mountPath: /usr/share/nginx/html
  volumes:
  - name: html-path
    persistentVolumeClaim:
      claimName: pvc1

7.2 进入Pod并写入index.html文件

 7.3 查看NFS服务器

 没问题，部署StorageClass成功
