1. 在Kubernetes集群中，安装EFS CSI驱动程序，使EFS存储可用于Kubernetes Pod：

kubectl apply -k "github.com/kubernetes-sigs/aws-efs-csi-driver/deploy/kubernetes/overlays/stable/?ref=master"

如果要支持xfs文件系统，请使用以下命令：

kubectl apply -k "github.com/kubernetes-sigs/aws-efs-csi-driver/deploy/kubernetes/overlays/stable/xfs/?ref=master"

2. 创建EFS访问点并为它们分配标签：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: efs-claim
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5Gi
  storageClassName: efs-sc
  volumeMode: Filesystem
  volumeName: efs-volume
  persistentVolumeReclaimPolicy: Retain
  dataSource:
    kind: VolumeSnapshot
    name: snap-apsimple
    apiGroup: snapshot.storage.k8s.io

apiVersion: v1
kind: PersistentVolume
metadata:
  name: efs-volume
spec:
  accessModes:
    - ReadWriteMany
  capacity:
    storage: 5Gi
  csi:
    driver: efs.csi.aws.com
    volumeHandle: fs-351b17a1
  volumeMode: Filesystem
  persistentVolumeReclaimPolicy: Retain
  mountOptions:
    - tls
  # Update the DNS name and file system ID with your EFS settings
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: topology.kubernetes.io/zone
          operator: In
          values:
          - us-west-2a
  resources:
    requests:
      storage: 5Gi
  storageClassName: efs-sc
  volumeName: efs-volume

3. 在持久卷声明中指定标签，以便多个持久卷声明可以指定同一访问点，并在Pod中使用
