Pod 不使用 PersistentVolume(PV) 和 PersistentVolumeClaim(PVC) 存储数据

Question

我创建了两个 pod 一个运行一个简单的 scala 应用程序，它使用 akkaHttp 将用户数据添加到 Elasticsearch 中，另一个运行 elasticsearch:8.4.5 的 Pod。还为 akka 创建了一个外部服务，为 elasticsearch 创建了一个内部服务。我可以使用邮递员将数据添加到 ES 中并获取数据。现在我想使用 Persistent-Volume（使我的应用程序有状态）来存储数据，即使是 pod 死亡并重新创建，这里是我的 YAML 文件。

部署.yaml（弹性搜索）

              valueFrom:

          volumeMounts:
            - name: elastic-storage
              mountPath: /storage/data
      volumes:
        - name: elastic-storage
          persistentVolumeClaim:
            claimName: elastic-pvc`

PersistentVolume.yaml

`apiVersion: v1
kind: PersistentVolume
metadata:
  name: elastic-pv

spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteMany
  volumeMode: Filesystem
  persistentVolumeReclaimPolicy: Retain
  hostPath:
    path: /storage/data
  nodeAffinity:
    required:
      nodeSelectorTerms:
        - matchExpressions:
            - key: kubernetes.io/hostname
              operator: In
              values:
                - minikube`

PersistentVolumeClaim.yaml

`apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: elastic-pvc

spec:
  volumeName: elastic-pv
  accessModes:
    - ReadWriteMany
  volumeMode: Filesystem
  resources:
    requests:
      storage: 1Gi
  storageClassName: ""
`

我能够将用户数据添加到 elasticsearch 中，但是当 pod 重新启动时数据也丢失并出现错误

An error occurred: [es/get] failed: [index_not_found_exception] no such index [user]

还有 minikube 中的目录“/storage/data”没有文件。

我的 YAML 文件有什么问题吗？
