kubernetes.persistentvolume.delete ​
Delete a cluster PersistentVolume (destructive; reclaims orphaned storage)
Deletes a cluster-scoped PersistentVolume. Swallows 404 so the workflow is idempotent — callers can safely delete one that was already removed.
This is the reclaim step for storage a teardown left behind: a Released volume under a Retain policy that no namespace will ever claim again. kubernetes.persistentvolume.list flags those as orphaned.
Destructive and unrecoverable. Under a Retain policy the PV object is the last cluster-side handle on the backing cloud disk, so deleting it both discards the data and, depending on the provisioner, may leave the disk itself allocated in the cloud account — check the provider console after a reclaim sweep rather than assuming the bill stopped.
A PV still Bound to a live PVC does not disappear on delete: Kubernetes marks it Terminating and its finalizer holds until the claim goes away. Delete the PVC first. This workflow reports what the API server accepted; it does not wait for the object to actually vanish.
Inputs:
- connection_uuid: Cloud connection UUID (required)
- name: PersistentVolume name (required)
Outputs:
- name, existed: bool existed=False means the PersistentVolume was already absent.
Plugin required: context.get_plugin("connection").kubernetes_runner_clients(connection_uuid, organization_uuid) must expose core_v1 with delete_persistent_volume.
