kubectl proxy &
kubectl get ns <namespace> -o json > delete-ns.json
sed -i 's/"kubernetes"//g' delete-ns.json
curl -k -H "Content-Type: application/json" -X PUT --data-binary @delete-ns.json http://127.0.0.1:8001/api/v1/namespaces/<namespace>/finalize

 

 

#!/bin/bash

if [ $# -ne 1 ]; then
  echo "script need 1 parameter"
  echo "ex) ./force-delete-ns.sh kubeflow"
  exit 1
fi
kubectl proxy &
kubectl get ns
kubectl get ns $1 -o json > delete-ns.json
sed -i 's/"kubernetes"//g' delete-ns.json
curl -k -H "Content-Type: application/json" -X PUT --data-binary @delete-ns.json http://127.0.0.1:8001/api/v1/namespaces/$1/finalize
kubectl get ns
