Delete a Kubernetes resource that is stuck "Terminating"

General Resource

Run the following command to force a resource to delete. It works by removing all finalizers. Only use this if a resource has become “stuck”.

kubectl patch resourcetype resource-name -n resource-namespace -p '{"metadata":{"finalizers":[]}}' --type=merge

Replace resourcetype with the type of resource (e.g. pod, helmrelease, etc…), replace resource-name with the name of your resource and resource-namespace with the name of the resource which the resource belongs to.

If the resource has become orphaned (i.e. the namespace a resource belongs to has been deleted), recreate the namespace and then run the above command for each resource.

Namespace

If a namespace is stuck and the above method doesn’t work, run the following command, replacing my-namespace with the name of your namespace to delete.

kubectl get ns my-namespace -o json | jq '.spec.finalizers = []' | kubectl replace --raw "/api/v1/namespaces/my-namespace/finalize" -f -
