Service -- Amazon EKS） 和 KubeSphere。 因为之前没有使用过 EKS 和 KubeSphere，所以这个过程也是一个试错的过程，在我使用 KubeSphere 的时候发现有一个日志服务，在好奇心的驱使下，我创建了它。 + +在我创建了日志服务（KubeSphere Logging System）以后，我发现我并不想使用它。（可能我只是想看看它到底是什么吧。）强迫症的我就想把它给删除掉。于是我在我的 EKS 中对他进行了强制删除： + +```bash +$ kubectl delete ns kubesphere-logging-system --force --grace-period=0 +``` + +让人尴尬的是，这个 Namespace 并没有立马删除，我自我安慰道，可能 Namespace 下边有其他没有删除的资源在等待删除，我再等等。。。 + +过了半个小时，再次查看删除进度： + +```bash +$ kubectl get ns kubesphere-logging-system +NAME STATUS AGE +kubesphere-logging-system Terminating 6d19h +``` + +它好像这地卡在了 Terminating 的状态。我试着寻找解决方法，参考这个 issue： http://github.com/kubernetes/kubernetes/issues/60807。但是这种方法要通过 API 才可以实现。EKS 是托管在 AWS 中的，我根本没有办法去操作 EKS 的后台。 + +终于我在这个 issue 中找到了答案：
