問(wèn)題一：刪除ns，一直處于Terminating狀態(tài)中
強(qiáng)制刪除也是出現(xiàn)報(bào)錯(cuò)
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.
Error from server (Conflict): Operation cannot be fulfilled on namespaces "devtesting": The system is ensuring all content is removed from this namespace. Upon completion, this namespace will automatically be purged by the system.

解決辦法：
kubectl get namespace devtesting -o json > devtesting.json
# cat devtesting.json

刪除其中的spec字段，因?yàn)閗8s集群是攜帶認(rèn)證的

執(zhí)行以下curl命令潭流，使用kube-apiserver的8080端口难菌，執(zhí)行刪除操作
curl -k -H "Content-Type: application/json" -X PUT --data-binary @devtesting.json http://127.0.0.1:8080/api/v1/namespaces/devtesting/finalize

備注：
如果kube-apiserver未開非安全端口试溯，可以手動(dòng)創(chuàng)建一個(gè)代理會(huì)話，
# kubectl proxy --port=8081
# curl -k -H "Content-Type: application/json" -X PUT --data-binary @devtesting.json http://127.0.0.1:8081/api/v1/namespaces/test/finalize
