#kubectl delete ns jenkins
Error from server (Conflict): Operation cannot be fulfilled on namespaces “jenkins”: The system is ensuring all content is removed from this namespace. Upon completion, this namespace will automatically be purged by the system.
1.尝试强制删除不行
删除时带上–force --grace-period=0参数 ,无法删除；
kubectl delete namespace jenkins --force --grace-period=0
#删除POD
kubectl delete pod PODNAME --force --grace-period=0
#删除NAMESPACE
kubectl delete namespace NAMESPACENAME --force --grace-period=0
2.kubectl get namespace monitoring -o json > tmp.json
然后打开tmp.json，删除其中的spec字段，即删除清空大括号里面数据，因为这边的K8s集群是带认证的，
3.又新开了窗口运行kubectl proxy跑一个API代理在本地的8081端口。
kubectl proxy --port=8081
4.curl -k -H “Content-Type: application/json” -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces/monitoring/finalize
