删除K8s Namespace时卡在Terminating状态

想要删除K8s里的一个Namespace,结果删除了所有该Namespace资源之后使用kubectl delete namespace test发现删除不掉,一直卡在Terminating状态,使用--force参数依然无法删除,报错:
Error from server (Conflict): Operation cannot be fulfilled on namespaces "test": The system is ensuring all content is removed from this namespace. Upon completion, this namespace will automatically be purged by the system.
找了一圈,发现这个Issue,里面有条评论

kubectl get namespace annoying-namespace-to-delete -o json > tmp.json
then edit tmp.json and remove”kubernetes”

curl -k -H “Content-Type: application/json” -X PUT –data-binary @tmp.json https://kubernetes-cluster-ip/api/v1/namespaces/annoying-namespace-to-delete/finalize

and it should delete your namespace,

跟着试了一下,很管用,直接就删除了:
先运行kubectl get namespace test -o json > tmp.json,拿到当前namespace描述,然后打开tmp.json,删除其中的spec字段。因为这边的K8s集群是带认证的,所以又新开了窗口运行kubectl proxy跑一个API代理在本地的8081端口。最后运行curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8001/api/v1/namespaces/test/finalize

搞定!
