StatefulSet 

        StatefulSet represents a set of pods with consistent identities. Identities are defined as:
  - Network: A single stable DNS and hostname.
  - Storage: As many VolumeClaims as requested.

The StatefulSet guarantees that a given network identity will always map to the same storage identity.
