## What this PR does After deleting a `Qdrant` app CR, the StatefulSet data PVC (`qdrant-storage-<release>-0`) was left orphaned in the tenant namespace, consuming storage permanently. StatefulSet-templated PVCs are never garbage-collected on StatefulSet deletion by default. The vendored upstream Qdrant chart does **not** support `persistentVolumeClaimRetentionPolicy` (verified: its `statefulset.yaml` never renders that field), so the OpenBAO-style value passthrough is not possible here. Instead this adds a `post-delete` PVC cleanup hook (modeled on the MariaDB hook) that deletes the release's PVCs by label. The chart's volumeClaimTemplate only stamps `app: qdrant` (shared by every Qdrant in a namespace), so to select PVCs safely per release this also passes `persistence.additionalLabels.app.kubernetes.io/instance: <release>` through the HelmRelease — giving the data PVC a release-unique label the hook selects on. The cleanup Job is hardened: runs as non-root (uid 65534), read-only root fs, all capabilities dropped, `seccompProfile: RuntimeDefault`; RBAC scoped to `persistentvolumeclaims`. A real cleanup failure is logged (not silently swallowed) but never blocks namespace teardown. > [!WARNING] > **Deleting a Qdrant app now permanently removes its data PVC and the vector data it holds.** > This is intentional and fixes the storage leak; the hook only fires on full > release deletion (not on scale-down). Back up before deleting. Fixes #3059. ### Release note ```release-note fix(qdrant): garbage-collect the StatefulSet data PVC when a Qdrant app is deleted, instead of leaving it orphaned. WARNING: deleting a Qdrant app now permanently removes its data PVC and the data it holds. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added a post-delete cleanup hook for Qdrant to remove leftover StatefulSet data PVCs after deletion. * Included hardened Kubernetes settings for the cleanup job to improve runtime safety. * **Tests** * Added Helm chart tests that validate the post-delete cleanup job and its RBAC permissions. * Enhanced end-to-end verification to confirm the data PVC is fully removed after deleting a Qdrant instance. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
