nfs 存储类

1. 建立nfs server

cat /etc/exports

/data/nfs_pro 192.168.31.0/24(rw,no_root_squash)

2.建立sa，绑定权限

kubectl create sa nfs-provisioner
kubectl create clusterrolebinding nfs-provisioner-clusterolebinding --clusterrole=cluster-admin --serviceaccount=default:nfs-provisioner

3.导入provisioner镜像 ，创建provisioner服务

docker  pull  registry.cn-beijing.aliyuncs.com/mydlq/nfs-subdir-external-provisioner:v4.0.0

kind: Deployment
apiVersion: apps/v1
metadata:
  name: nfs-provisioner
spec:
  selector:
    matchLabels:
       app: nfs-provisioner
  replicas: 1
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: nfs-provisioner
    spec:
      serviceAccount: nfs-provisioner
      containers:
        - name: nfs-provisioner
          image: registry.cn-beijing.aliyuncs.com/mydlq/nfs-subdir-external-provisioner:v4.0.0
          imagePullPolicy: IfNotPresent
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:
            - name: PROVISIONER_NAME
              value: example.com/nfs                    // 后面会用到
            - name: NFS_SERVER
              value: 192.168.40.180
            - name: NFS_PATH
              value: /data/nfs_pro/
      volumes:
        - name: nfs-client-root
          nfs:
            server: 192.168.40.180
            path: /data/nfs_pro/

4.创建nfs storageclass

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs
provisioner: example.com/nfs    //上一步环境变量里的名称

kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
nfs example.com/nfs Delete Immediate false 70s
