当 Pod 被删除并与我的 postgresql 数据库一起部署回时，我的 Kubernetes StorageClass 卷不会保留现有数据。当我删除 Pod 时，会创建新的 Pod，但数据库为空。
我遵循了不同版本的教程的变体（https://kubernetes.io/docs/concepts/storage/persistent-volumes/ https://kubernetes.io/docs/concepts/storage/persistent-volumes/）但似乎没有任何作用。
我粘贴了所有 YAML 文件，因为问题可能出在组合中。

当我包含保留策略时，我收到此错误：
@cloudshell:~ (academic-veld-230622)$ kubectl apply -f storage-google.yaml
error: error validating "storage-google.yaml": error validating data:
ValidationError(PersistentVolumeClaim.spec): unknown field "persistentVolumeReclaimPolicy" in io.k8s.api.core.v1.PersistentVolumeClaimSpec; if you choose to ignore these errors, turn validation off with --validate=false
请，如果您知道有效的公共图像的完整示例（在 postgresql 中，我可以使其与 Mongo 一起工作），我将非常感激。
谢谢大家。
