k8s、nfs、storageclass、动态、nfs-provisioner

1、创建RBAC

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nfs-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"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: run-nfs-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-provisioner
    namespace: default
roleRef:
  kind: ClusterRole
  name: nfs-provisioner-runner
  apiGroup: rbac.authorization.k8s.io
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: leader-locking-nfs-provisioner
rules:
  - apiGroups: [""]
    resources: ["endpoints"]
    verbs: ["get", "list", "watch", "create", "update", "patch"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: leader-locking-nfs-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-provisioner
    # replace with namespace where provisioner is deployed
    namespace: default
roleRef:
  kind: Role
  name: leader-locking-nfs-provisioner
  apiGroup: rbac.authorization.k8s.io

2、创建sa

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-provisioner

3、部署provisoner

kind: Deployment
apiVersion: extensions/v1beta1
metadata:
  name: nfs-provisioner
spec:
  replicas: 1
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: nfs-provisioner
    spec:
      serviceAccount: nfs-provisioner
      containers:
        - name: nfs-provisioner
          image: registry.cn-hangzhou.aliyuncs.com/open-ali/nfs-client-provisioner
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: example.com/nfs
            - name: NFS_SERVER
              value: 10.57.31.22
            - name: NFS_PATH
              value: /data/nfs
      volumes:
        - name: nfs-client-root
          nfs:
            server: 10.57.31.22
            path: /data/nfs
# node所在机器记得安装nfs-utils,命令：yum install nfs-utils

4、定义StorageClass

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: nfs
provisioner: example.com/nfs

5、试一试

apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
  name: web
spec:
  serviceName: nginx1
  replicas: 2
  volumeClaimTemplates:
  - metadata:
      name: test
      annotations:
        volume.beta.kubernetes.io/storage-class: "nfs"
    spec:
      accessModes: [ "ReadWriteOnce" ]
      resources:
        requests:
          storage: 1Gi
  template:
    metadata:
      labels:
        apps: nginx1
    spec:
      serviceAccount: nfs-provisioner
      containers:
      - name: nginx1
        image: hub.c.163.com/library/nginx
        imagePullPolicy: IfNotPresent
        volumeMounts:
        #- mountPath: "/persistentvolumes"
        - mountPath: "/test"
          name: test

在部署应用的时候，volumeClaimTemplates中声明好即可
