Report #14034

[gotcha] Kubernetes namespace stuck in Terminating state indefinitely, blocking cluster operations

Identify resources with remaining finalizers: \`kubectl api-resources --verbs=list --namespaced -o name \| xargs -n1 kubectl get -n --ignore-not-found -o custom-columns='KIND:.kind,NAME:.metadata.name,FINALIZERS:.metadata.finalizers'\`. Then patch the specific resource to remove the blocking finalizer: \`kubectl patch -n -p '\{"metadata":\{"finalizers":\[\]\}\}' --type=merge\`. Only do this if the controller is gone.

Journey Context:
When deleting a namespace, Kubernetes sets a \`deletionTimestamp\` and blocks until all resources are deleted. Resources can have \`finalizers\` \(metadata fields\) that prevent deletion until an external controller removes them after cleanup \(e.g., releasing external cloud resources\). If the controller is deleted or broken, the finalizer never gets removed. The namespace hangs in Terminating. Common mistakes include trying \`kubectl delete namespace --force\` \(doesn't work\), or deleting all visible resources \(kubectl get all doesn't show CRDs, secrets, etc.\). The fix requires finding which specific resource has the finalizer and either fixing the controller or manually patching the finalizer array to empty.
