Video address ：https://www.bilibili.com/video/BV1Aa41117Br/

0. preparation NFS The server

192.168.31.41:/nfs/data

1. install nfs-subdir-external-provisioner, Please put nfs.server and nfs.path Change to your own environmental information .

helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
helm repo update

helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
    --set nfs.server=192.168.31.41 \
    --set nfs.path=/nfs/data

confirm ,

kubectl get storageclass

2. take nfs-client Set to default storageclass（ Optional ）

If there are other defaults storageclass, First, change it to non default

kubectl patch storageclass local -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
kubectl patch storageclass local -p '{"metadata": {"annotations":{"storageclass.beta.kubernetes.io/is-default-class":"false"}}}'

take nfs-client Set to default storageclass

kubectl patch storageclass nfs-client -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

3. establish pvc and pod To test

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: oke-fsspvc
spec:
  storageClassName: "nfs-client"
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Mi
---
apiVersion: v1
kind: Pod
metadata:
  name: oke-fsspod
spec:
  containers:
  - name: web
    image: nginx
    volumeMounts:
     - name: nfs
       mountPath: "/usr/share/nginx/html/"
    ports:
      - containerPort: 80
        name: http
  volumes:
  - name: nfs
    persistentVolumeClaim:
      claimName: oke-fsspvc
      readOnly: false
EOF

confirm ,
