Report #37895

[gotcha] Kubernetes namespace or custom resource stuck in 'Terminating' state indefinitely, kubectl delete hangs

Check for finalizers on the object: \`kubectl get -o jsonpath='\{.metadata.finalizers\}'\`. If the controller responsible for processing the finalizer is deleted or broken, you must either restore the controller or manually patch the object to remove the finalizers: \`kubectl patch --type=merge -p '\{"metadata":\{"finalizers":\[\]\}\}'\`. For namespaces stuck deleting, check for leftover resources with finalizers \(e.g., PVCs, CRDs\) inside the namespace.

Journey Context:
Finalizers are metadata keys that prevent objects from being deleted until external controllers perform cleanup \(e.g., deleting external cloud resources, removing load balancers\). When a user runs \`kubectl delete\`, the object enters 'Terminating', the API server sets a deletion timestamp, and waits for the finalizers array to be empty. If the controller pod is scaled down, crashed, or the CRD was deleted before the instance, the finalizer is never removed. The object hangs forever. The fix requires manual intervention to patch out the finalizer \(accepting resource leakage\) or restoring the controller. This is common in CI/CD teardowns or Helm uninstalls where CRDs are deleted before CRs.
