Namespace stuck in "Terminating" state

A Kubernetes namespace stuck in a terminating state typically happens when Kubernetes is unable to clean up all resources in that namespace. Need to describe namespace this will show up the reason why its stuck in terminating state Most common scenario: Customer delete tenant but k8s namespace still exists Describe k8s namespace which is stuck in terminating state kubectl describe ns {Namespace name} NamespaceDeletionDiscoveryFailure True Mon, 02 Jun 2025 10:08:23 +0530 DiscoveryFailed Discovery failed for some groups, 1 failing: unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: stale GroupVersion discovery: metrics.k8s.io/v1beta1 Get the status of metrics-server apiserver kubectl get apiservice | grep metrics-server v1beta1.metrics.k8s.io kube-system/metrics-server False (MissingEndpoints) 3m29s Metrics-server not deployed: if metrics server pod is stuck in pending state, delete metrics-server apiservice kubectl delete apiservice v1beta1.metrics.k8s.io Issue with metrics-server configuration: If metrics-server deployment pod is in running state, it has configuration issue. Easiest way to fix is to delete metrics-server deployment, wait for metrics-server pod to be in running state. Delete metrics-server k8s service. Get the status of metrics-server apiservice: kubectl get apiservice | grep metrics-server v1beta1.metrics.k8s.io kube-system/metrics-server True 12m Above apiservice status is changed from False (MissingEndpoints) to True Verify namespace is deleted: kubectl get ns | grep {namespace}
