Terminating stuck namespaces using kubectl

Description

After installing a helm deployment or testing something and you removed everything, sometimes we faced a stuck namespace, so how to kill it?

Terminating stuck namespace

  • Executing the below command:
kubectl get namespace "$namespace-to-delete" -o json   | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/"   | kubectl replace --raw /api/v1/namespaces/$namespace-to-delete/finalize -f -
  • Or execute the below command:
kubectl get namespace "stucked-namespace" -o json \
  | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" \
  | kubectl replace --raw /api/v1/namespaces/stucked-namespace/finalize -f -
