type PersistentVolumePruner

type PersistentVolumePruner struct {
	ClientSet kubernetes.Interface
}

PersistentVolumePruner provides a Prune() method to remove unused statefulset PVC and their underlying PVs. The underlying PVs SHOULD have their reclaim policy set to delete.

func (*PersistentVolumePruner) Prune

func (p *PersistentVolumePruner) Prune(ctx context.Context, tc *v1alpha1.TiflowCluster) error

Prune locates and removes all PVCs that belong to a given statefulSet but are not in use. The underlying PVs' reclaim policy should be set to delete, other options may result in leaking volumes which cost us money.
