Persistent volume claim.

Developers can use persistent volume claims (PVCs) to request PV resources without having specific knowledge of the underlying storage infrastructure. PVCs are specific to a project, and are created and used by developers as a means to use a PV. PV resources on their own are not scoped to any single project; they can be shared across the entire ...

Persistent volume claim. Things To Know About Persistent volume claim.

kubectl edit pv <your-pv-name-goes-here>. In the editor, remove the entire "claimRef" section.
