在部署kuboard控制平台的时候，不规范删除，导致ns状态为Terminating
[root@master01 ~]# kubectl delete namespace kuboard
^C
root@master01 ~]# kubectl get ns
NAME STATUS AGE
default Active 25h
kube-flannel Active 24h
kube-node-lease Active 25h
kube-public Active 25h
kube-system Active 25h
kuboard Terminating 21h
[root@master01 ~]#
尝试1，还是不行
使用 -grace-period=0 --force 参数强行删除,还是不行
[root@master01 ~]# kubectl delete namespace kuboard --grace-period=0 --force
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
namespace "kuboard" force deleted
^C
[root@master01 ~]#
[root@master01 ~]# kubectl get ns
NAME STATUS AGE
default Active 39h
kube-flannel Active 39h
kube-node-lease Active 39h
kube-public Active 39h
kube-system Active 39h
kuboard Terminating 36h
尝试2，调用kubernetes-API删除

1、首先，获取要删除 NameSpace 的 JSON 文件：
替换其中的 <terminating-namespace> 为实际 namespace
kubectl get namespace <terminating-namespace> -o json >tmp.json
[root@master01 ~]# kubectl get namespace kuboard -o json > tmp.json
2、编辑上一步导出的 json 文件，去除 spec.finalizers 配置
[root@master01 ~]# vim tmp.json
····
"spec": {
"finalizers": []
····
3、打开另一个ssh窗口运行kubectl proxy开启代理
[root@master01 ~]# kubectl proxy
Starting to serve on 127.0.0.1:8001
4、删除 namespace
其中 tmp.json 为第一步中导出的 json 文件，
需替换为实际的 namespace
$ curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces//finalize
[root@master01 ~]# kubectl get ns
NAME STATUS AGE
default Active 39h
kube-flannel Active 39h
kube-node-lease Active 39h
kube-public Active 39h
kube-system Active 39h
kuboard Terminating 36h
[root@master01 ~]#
[root@master01 ~]# curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces/kuboard/finalize
}[root@master01 ~]# kubectl get ns
NAME STATUS AGE
default Active 39h
kube-flannel Active 39h
kube-node-lease Active 39h
kube-public Active 39h
kube-system Active 39h
[root@master01 ~]#
完成对namespace状态Terminating的删除
