  Volume populators and data sourcesFEATURE STATE:
  Kubernetes v1.24 [beta]Kubernetes supports custom volume populators.
  To use custom volume populators, you must enable the AnyVolumeDataSource
  feature gate for
  the kube-apiserver and kube-controller-manager.Volume populators take advantage of a PVC spec field called dataSourceRef. Unlike the
  dataSource field, which can only contain either a reference to another PersistentVolumeClaim
  or to a VolumeSnapshot, the dataSourceRef field can contain a reference to any object in the
  same namespace, except for core objects other than PVCs. For clusters that have the feature
  gate enabled, use of the dataSourceRef is preferred over dataSource.Cross namespace data sourcesFEATURE STATE:
  Kubernetes v1.26 [alpha]Kubernetes supports cross namespace volume data sources.
  To use cross namespace volume data sources, you must enable the AnyVolumeDataSource
  and CrossNamespaceVolumeDataSource
  feature gates for
  the kube-apiserver and kube-controller-manager.
  Also, you must enable the CrossNamespaceVolumeDataSource feature gate for the csi-provisioner.Enabling the CrossNamespaceVolumeDataSource feature gate allows you to specify
  a namespace in the dataSourceRef field.Note:When you specify a namespace for a volume data source, Kubernetes checks for a
  ReferenceGrant in the other namespace before accepting the reference.
  ReferenceGrant is part of the gateway.networking.k8s.io extension APIs.
  See ReferenceGrant
  in the Gateway API documentation for details.
  This means that you must extend your Kubernetes cluster with at least ReferenceGrant
