The naming convention of a ClusterResourceOverrideSnapshot is {ClusterResourceOverride}-{resourceIndex}. resourceIndex will begin with 0. Each snapshot MUST have the following labels:

  • `OverrideTrackingLabel` which points to its owner ClusterResourceOverride.
  • `IsLatestSnapshotLabel` which indicates whether the snapshot is the latest one.
