本篇几年前写的，非AI文，怀念那个没有AI自己下功夫研究的时代。
本篇文章给大家介绍名称空间删除不了怎么办，解决方案亲测有效！！！
如果你能看到这篇文章，想必你已经无数次尝试 kubectl delete ns xxx 了，不管是强制删除的 kubectl delete ns xxx --force 还是 kubectl delete ns xxx --force --grace-period=0，删除完查看名称空间还是没有删除，状态显示STATUS，详细信息根本看不懂！！！
此时请你跟着我做如下步骤，不要嫌麻烦，操作完后，你会有所收获的！
1、首先，我们查看名称空间，发现有几个Terminating的名称空间，我们以删除 koten-efk01 为例。
[root@Master231 ~]# kubectl get ns
NAME STATUS AGE
default Active 13d
koten-efk01 Terminating 3h52m
koten-efk02 Terminating 3h37m
koten-efk03 Active 146m
koten-efk04 Terminating 137m
kube-flannel Active 13d
kube-node-lease Active 13d
kube-public Active 13d
kube-system Active 13d2、将要删除的名称空间的资源清单以json格式导出
[root@Master231 ~]# kubectl get namespaces koten-efk01 -o json > koten-efk01.json3、修改导出的json文件，删除spec下面的所有字段，但是spec本身不要删除。
删除前
删除后
4、打开一个新的shell会话，执行 kubectl proxy，启用代理
[root@Master231 ~]# kubectl proxy
Starting to serve on 127.0.0.1:80015、在原shell会话调用Api删除，注意修改下面命令的json文件名称和要删除的名称空间
[root@Master231 ~]# curl -k -H "Content-Type: application/json" -X PUT --data-binary @koten-efk01.json http://127.0.0.1:8001/api/v1/namespaces/koten-efk01/finalize

}[root@Master231 ~]# 6、再次查看发现之前的名称空间成功被删除
[root@Master231 ~]# kubectl get ns
