I've had a "stuck" namespace that I deleted showing in this eternal "terminating" status.

Assuming you've already tried to force-delete resources like: Pods stuck at terminating status, and your at your wits' end trying to recover the namespace...

You can force-delete the namespace (perhaps leaving dangling resources):

(
NAMESPACE=your-rogue-namespace
kubectl proxy &
kubectl get namespace $NAMESPACE -o json |jq '.spec = {"finalizers":[]}' >temp.json
curl -k -H "Content-Type: application/json" -X PUT --data-binary @temp.json 127.0.0.1:8001/api/v1/namespaces/$NAMESPACE/finalize
)

  • This is a refinement of the answer here, which is based on the comment here.

  • I'm using the jq utility to programmatically delete elements in the finalizers section. You could do that manually instead.

  • kubectl proxy creates the listener at 127.0.0.1:8001 by default. If you know the hostname/IP of your cluster master, you may be able to use that instead.

  • The funny thing is that this approach seems to work even when using kubectl edit making the same change has no effect.
