| 可参照官方的配置 https://github.com/kubernetes-incubator/external-storage/tree/master/nfs-client/deploy
 第一种 不使用rbac认证的
 
 1,创建serviceaccount.yaml
 apiVersion: v1
 kind: ServiceAccount
 metadata:
 name: nfs-client-provisioner  2,部署nfs client
 kind: Deployment
 apiVersion: extensions/v1beta1
 metadata:
 name: nfs-provisioner
 spec:
 replicas: 1
 strategy:
 type: Recreate
 template:
 metadata:
 labels:
 app: nfs-provisioner
 spec:
 serviceAccount: nfs-client-provisioner  #这个要与刚才创建的serviceaccount 的名字一致
 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 #这里名字自定义,要记住storageclass 后面要用到
 - name: NFS_SERVER
 value: [已配置的NFS系统的IP地址]
 - name: NFS_PATH
 value: [已配置的NFS系统的挂载路径]
 volumes:
 - name: nfs-client-root
 nfs:
 server: [已配置的NFS系统的IP地址]
 path: [已配置的NFS系统的挂载路径] #这里需要注意,如果用的公有云服务的nfs 或者nas,必须要提前创建好目录  可以看到nfs-client pod 正常运行,说明没有问题
 3,创建storageclass
 kind: StorageClass
 apiVersion: storage.k8s.io/v1
 metadata:
 name: nfs
 provisioner: example.com/nfs #这里的名字要跟之前创建nfs-client deployment里写的名字一样  这样没有基于rbac的storageclass 动态存储就创建好了
 验证:
 1,创建pvc
 kind: PersistentVolumeClaim
 apiVersion: v1
 metadata:
 name: test-claim1
 spec:
 accessModes:
 - ReadWriteMany
 resources:
 requests:
 storage: 1Mi
 storageClassName: nfs  2,创建pod
 
 kind: Pod
 apiVersion: v1
 metadata:
 name: test-pod
 spec:
 containers:
 - name: test-pod
 image: busybox
 command:
 - "/bin/sh"
 args:
 - "-c"
 - "touch /mnt/SUCCESS && exit 0 || exit 1"
 volumeMounts:
 - name: nfs-pvc
 mountPath: "/mnt"
 restartPolicy: "Never"
 volumes:
 - name: nfs-pvc
 persistentVolumeClaim:
 claimName: test-claim1查看Pod状态是否变为Completed。如果是,则应该能在NFS系统的共享路径中看到一个SUCCESS文件。
 这样,StorageClass动态创建PV的功能就成功实现了
 第二 使用rbac的
 1,创建serviceaccount.yaml
 apiVersion: v1
 kind: ServiceAccount
 metadata:
 name: nfs-client-provisioner
 namespace: fabric8  2,创建nfs客户端deployment.yaml
 kind: Deployment
 apiVersion: extensions/v1beta1
 metadata:
 name: nfs-client-provisioner
 namespace: fabric8
 spec:
 replicas: 1
 strategy:
 type: Recreate
 template:
 metadata:
 labels:
 app: nfs-client-provisioner
 spec:
 serviceAccount: nfs-client-provisioner
 containers:
 - name: nfs-client-provisioner
 image: quay.io/external_storage/nfs-client-provisioner:latest
 volumeMounts:
 - name: nfs-client-root
 mountPath: /persistentvolumes #这里不能修改
 env:
 - name: PROVISIONER_NAME
 value: shiwaixiangcun.cn/nfs #这里自定义
 - name: NFS_SERVER
 value: 172.18.xxx.xxx    #写nfs server地址
 - name: NFS_PATH
 value: /localmnt/storage
 volumes:
 - name: nfs-client-root
 nfs:
 server: 172.18.xxx.xxx
 path: /localmnt/storage    #和之前一样,挂在之前,一定要提前创建,不然k8s 不认识,也不能自动创建
 
 3,创建集群绑定规则clusterrolebinding.yaml
 kind: ClusterRoleBinding
 apiVersion: rbac.authorization.k8s.io/v1alpha1
 metadata:
 name: run-nfs-client-provisioner
 subjects:
 - kind: ServiceAccount
 name: nfs-client-provisioner
 namespace: fabric8
 roleRef:
 kind: ClusterRole
 name: nfs-client-provisioner-runner
 apiGroup: rbac.authorization.k8s.io  4,创建集群角色clusterrole.yaml
 kind: ClusterRole
 apiVersion: rbac.authorization.k8s.io/v1alpha1
 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"]  5,创建storageclass.yaml
 apiVersion: storage.k8s.io/v1beta1
 kind: StorageClass
 metadata:
 name: standard
 provisioner: shiwaixiangcun.cn/nfs #这里跟之前创建nfs client端里定义的名字一样
 
 验证创建效果
 1,创建pvc
 kind: PersistentVolumeClaim
 apiVersion: v1
 metadata:
 name: test-claim
 namespace: fabric8
 annotations:
 volume.beta.kubernetes.io/storage-class: "standard"spec:
 accessModes:
 - ReadWriteMany
 resources:
 requests:
 storage: 1Mi  2,创建pod并挂在pvc
 kind: Pod
 apiVersion: v1
 metadata:
 name: test-pod
 namespace: fabric8
 spec:
 containers:
 - name: test-pod
 image: busybox    command:
 - "/bin/sh"
 args:
 - "-c"
 - "touch /mnt/SUCCESS && exit 0 || exit 1"
 volumeMounts:
 - name: nfs-pvc
 mountPath: "/mnt"
 restartPolicy: "Never"
 volumes:
 - name: nfs-pvc
 persistentVolumeClaim:
 claimName: test-claim
 
 
 
 最后创建StatefulSet案例
 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:
 app: nginx1
 spec:
 serviceAccount: nfs-provisioner
 containers:
 - name: nginx1
 image: nginx
 imagePullPolicy: IfNotPresent
 volumeMounts:
 - mountPath: "/persistentvolumes"
 name: test
