#6692 [BUG] Invalid namespaced owner reference attached to mutatingwebhookconfigurations Issue created by mhotan ### Flyte & Flytekit version Latest ### Describe the bug Currently, we are adding an owner reference that is namespaced to

<http://mutatingwebhookconfigurations.admissionregistration.k8s.io|mutatingwebhookconfigurations.admissionregistration.k8s.io>

, specifically the

flyte-pod-webhook

. This is not valid and will cause mgcs to be orphaned on uninstall.

Cluster-scoped dependents can only specify cluster-scoped owners. In v1.20+, if a cluster-scoped dependent specifies a namespaced kind as an owner, it is treated as having an unresolvable owner reference, and is not able to be garbage collected.

Ref: https://kubernetes.io/docs/concepts/overview/working-with-objects/owners-dependents/#owner-references-in-object-specifications ### Expected behavior At a minimum, we should not set the owner reference and set labels to label owners. ### Additional context to reproduce No response ### Screenshots No response ### Are you sure this issue hasn't been raised already? • Yes ### Have you read the Code of Conduct? • Yes flyteorg/flyte
