안녕하세요. 좋은 강의 잘 보고 있습니다.

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.10", GitCommit:"62876fc6d93e891aa7fbe19771e6a6c03773b0f7", GitTreeState:"clean", BuildDate:"2020-10-15T01:52:24Z", GoVersion:"go1.13.15", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.14", GitCommit:"5de7fd1f9555368a86eb0f8f664dc58055c17269", GitTreeState:"clean", BuildDate:"2021-01-18T09:31:01Z", GoVersion:"go1.13.15", Compiler:"gc", Platform:"linux/amd64"}

Namespace를 삭제하면, Terminating 상태로 삭제가 되지 않습니다.

sansae@dev$ kubectl get ns
NAME              STATUS        AGE
default           Active        21d
dev               Active        47h
ingress-basic     Terminating   7d3h
ingress-nginx     Active        72m
kube-node-lease   Active        21d
kube-public       Active        21d
kube-system       Active        21d

아래 방법으로 시도하였으나, 마찬가지 삭제가 되지 않아요 ㅠㅠ;

$ kubectl get namespace ingress-basic -o json > tmp.json
$ kubectl proxy --prot=8888 &
$ curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:8888/api/v1/namespaces/ingress-basic/finalize

CURL실행 응답값.
