kubernetes - pod 事件显示 persistentvolumeclaim "flink-pv-claim-11"正在 kubernetes 中被删除，但绑定(bind)成功

Question

我将 persistentvolumeclaim 绑定(bind)到我的 Job 的 pod 中，它显示:

persistentvolumeclaim "flink-pv-claim-11" is being deleted

但是持久卷声明存在并且绑定(bind)成功。

并且 pod 没有日志输出。我应该怎么做才能解决这个问题？这是工作 yaml:

apiVersion: batch/v1
kind: Job
metadata:
  name: flink-jobmanager-1.11
spec:
  template:
    metadata:
      labels:
        app: flink

                path: log4j-console.properties

          persistentVolumeClaim:
            claimName: flink-pv-claim-11

确保与此 PVC 关联的作业已删除。如果任何其他作业/pod 正在运行并使用此 pvc，则在删除作业/pod 之前，您无法删除 PVC。
要从 PVC 中查看当前正在使用哪些资源，请尝试运行:
kubectl 获取 pod --all-namespaces -o=json | jq -c\'.items[] | {名称:.metadata.name，命名空间:.metadata.namespace，声明名称:.spec.volumes[] | select( 有 ("persistentVolumeClaim") ).persistentVolumeClaim.claimName }'
