nfs-client-provisioner使用

nfs服务器搭建：

1. 挂载硬盘（一般使用单独的硬盘）

mount /dev/sdb /nfsdata

 

2. 安装包

yum install nfs-utils rpcbind -y

 

3. 修改/etc/exports文件

# cat /etc/exports

/nfsdata    *(rw,sync,no_root_squash,no_subtree_check)

 

4. 启动nfs-server和rpcbind

systemctl start nfs-server rpcbind

systemctl enable nfs-server rpcbind

 

5. 查看nfs是否就绪

# showmount -e

 

nfs-client-provisioner配置：

git clone https://github.com/kubernetes-incubator/external-storage.git

 

cd external-storage/nfs-client/deploy

 

1. 创建serviceAccount

kubectl apply -f objects/serviceaccount.yaml

 

2. 创建StorageClass(sc)

kubectl apply -f class.yaml

 

3. 创建nfs-client-provisioner deployment

修改deployment.yaml中NFS服务器所在IP地址和NFS存储目录，其他均不用改

apiVersion: apps/v1

kind: Deployment

metadata:

  name: nfs-client-provisioner

  labels:

    app: nfs-client-provisioner

  # replace with namespace where provisioner is deployed

  namespace: default

spec:

  replicas: 1

  strategy:

    type: Recreate

  selector:

    matchLabels:

      app: nfs-client-provisioner

  template:

    metadata:

      labels:

        app: nfs-client-provisioner

    spec:

      serviceAccountName: nfs-client-provisioner

      containers:

        - name: nfs-client-provisioner

          image: quay.io/external_storage/nfs-client-provisioner:latest

          volumeMounts:

            - name: nfs-client-root

              mountPath: /persistentvolumes

          env:

            - name: PROVISIONER_NAME

              value: fuseim.pri/ifs

            - name: NFS_SERVER

              value: 172.20.192.117

            - name: NFS_PATH

              value: /nfsdata/pv3

      volumes:

        - name: nfs-client-root

          nfs:

            server: 172.20.192.117

            path: /nfsdata/pv3

 

4. 设置权限

kubectl apply -f rbac.yaml

 

5. 测试pvc（pod与pvc一一对应）

kubectl apply -f test-claim.yaml

kuctl get pvc

 

6. 测试pod

kubectl apply -f test-pod.yaml

 

7. 查看nfs服务器，已有文件

ls -lh /nfsdata/pv3/default-test-claim-pvc-344dcbf9-2122-46a6-85ed-8de42c7f23ef/SUCCESS
