Underlying clusters so that applications can be agnostic to the specifics of theĬluster they run on and application deployment requires no cluster specific knowledge. Kubernetes aims to create an abstraction layer between distributed applications and Underpinning all these features is the Kubernetes goal of workload portability: The Kubernetes volume plugin system already provides a powerful abstraction thatĪutomates the provisioning, attaching, mounting, resizing, and snapshotting of block Why add volume group snapshots to Kubernetes? New volumes (pre-populated with the snapshot data) or to restore existing volumes toĪ previous state (represented by the snapshots). ![]() A group snapshot can be used either to rehydrate A group snapshot represents “copies” from multiple volumes thatĪre taken at the same point-in-time.
