如何彻底删除EKS中一直卡在Terminating的Namespace _namespace

大鹏一日同风起，扶摇直上九万里。这篇文章主要讲述如何彻底删除EKS中一直卡在Terminating的Namespace相关的知识，希望能为你提供帮助。
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。）强迫症我的，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 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，我自我安慰到，可能 Namespace 下边有其他没有删除的资源在等待删除，我在等等。。。
过了半个小时，我去查看的时候

[root@ip-10-0-100-206 ~]# kubectl getnskubesphere-logging-system NAMESTATUSAGE kubesphere-logging-systemTerminating6d19h

【如何彻底删除EKS中一直卡在Terminating的Namespace】它好像这地卡在了 Terminating 的状态。
我试着寻找解决方法，http://github.com/kubernetes/kubernetes/issues/60807 但是这中方法要通过 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。
我开始后悔我为什么要去安装它，我本可以不折腾的。但是回想如果我不去安装它的话，我肯定会像想在这样难过，因为我无法了解它（KubeSphere Logging System）到底是什么样的。
终于我找到了 commented https://github.com/kubernetes/kubernetes/issues/60807#issuecomment-663853215
如何彻底删除 namespace 获取namespace的详情信息并转为json

kubectl get namespace kubesphere-logging-system -o json > kubesphere-logging-system.json

打开 json 文件编辑

"apiVersion": "v1", "kind": "Namespace", "metadata": "creationTimestamp": "2021-12-31T05:03:58Z", "deletionTimestamp": "2022-01-05T08:05:40Z", "labels": "kubesphere.io/namespace": "kubesphere-logging-system", "kubesphere.io/workspace": "system-workspace" , "managedFields": ["apiVersion": "v1", "fieldsType": "FieldsV1", "fieldsV1": "f:metadata": "f:labels": ".": , "f:kubesphere.io/namespace": , "f:ownerReferences": ".": , "k:\\"uid\\":\\"6d535470-2592-4f3c-a155-eabc362c339d\\"": ".": , "f:apiVersion": , "f:blockOwnerDeletion": , "f:controller": , "f:kind": , "f:name": , "f:uid": , "manager": "controller-manager", "operation": "Update", "time": "2021-12-31T05:04:01Z" ,"apiVersion": "v1", "fieldsType": "FieldsV1", "fieldsV1": "f:metadata": "f:labels": "f:kubesphere.io/workspace": , "f:status": "f:phase": , "manager": "kubectl", "operation": "Update", "time": "2021-12-31T05:04:01Z" ,"apiVersion": "v1", "fieldsType": "FieldsV1", "fieldsV1": "f:status": "f:conditions": ".": , "k:\\"type\\":\\"NamespaceContentRemaining\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceDeletionContentFailure\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceDeletionDiscoveryFailure\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceDeletionGroupVersionParsingFailure\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceFinalizersRemaining\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "manager": "kube-controller-manager", "operation": "Update", "time": "2022-01-05T08:05:47Z"], "name": "kubesphere-logging-system", "ownerReferences": ["apiVersion": "tenant.kubesphere.io/v1alpha1", "blockOwnerDeletion": true, "controller": true, "kind": "Workspace", "name": "system-workspace", "uid": "6d535470-2592-4f3c-a155-eabc362c339d"], "resourceVersion": "7376520", "uid": "2b76e9b1-75f2-4a2e-a819-73b36aea188e" , "spec": "finalizers": [ "kubernetes" # 将此行删除 ] , "status": "conditions": ["lastTransitionTime": "2022-01-05T08:05:47Z", "message": "All resources successfully discovered", "reason": "ResourcesDiscovered", "status": "False", "type": "NamespaceDeletionDiscoveryFailure" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "All legacy kube types successfully parsed", "reason": "ParsedGroupVersions", "status": "False", "type": "NamespaceDeletionGroupVersionParsingFailure" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "All content successfully deleted, may be waiting on finalization", "reason": "ContentDeleted", "status": "False", "type": "NamespaceDeletionContentFailure" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "Some resources are remaining: fluentbits.logging.kubesphere.io has 1 resource instances", "reason": "SomeResourcesRemain", "status": "True", "type": "NamespaceContentRemaining" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "Some content in the namespace has finalizers remaining: fluentbit.logging.kubesphere.io in 1 resource instances", "reason": "SomeFinalizersRemain", "status": "True", "type": "NamespaceFinalizersRemaining"], "phase": "Terminating"

找到 spec 将 finalizers 下的 kubernetes 删除
具体如下

"apiVersion": "v1", "kind": "Namespace", "metadata": "creationTimestamp": "2021-12-31T05:03:58Z", "deletionTimestamp": "2022-01-05T08:05:40Z", "labels": "kubesphere.io/namespace": "kubesphere-logging-system", "kubesphere.io/workspace": "system-workspace" , "managedFields": ["apiVersion": "v1", "fieldsType": "FieldsV1", "fieldsV1": "f:metadata": "f:labels": ".": , "f:kubesphere.io/namespace": , "f:ownerReferences": ".": , "k:\\"uid\\":\\"6d535470-2592-4f3c-a155-eabc362c339d\\"": ".": , "f:apiVersion": , "f:blockOwnerDeletion": , "f:controller": , "f:kind": , "f:name": , "f:uid": , "manager": "controller-manager", "operation": "Update", "time": "2021-12-31T05:04:01Z" ,"apiVersion": "v1", "fieldsType": "FieldsV1", "fieldsV1": "f:metadata": "f:labels": "f:kubesphere.io/workspace": , "f:status": "f:phase": , "manager": "kubectl", "operation": "Update", "time": "2021-12-31T05:04:01Z" ,"apiVersion": "v1", "fieldsType": "FieldsV1", "fieldsV1": "f:status": "f:conditions": ".": , "k:\\"type\\":\\"NamespaceContentRemaining\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceDeletionContentFailure\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceDeletionDiscoveryFailure\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceDeletionGroupVersionParsingFailure\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "k:\\"type\\":\\"NamespaceFinalizersRemaining\\"": ".": , "f:lastTransitionTime": , "f:message": , "f:reason": , "f:status": , "f:type": , "manager": "kube-controller-manager", "operation": "Update", "time": "2022-01-05T08:05:47Z"], "name": "kubesphere-logging-system", "ownerReferences": ["apiVersion": "tenant.kubesphere.io/v1alpha1", "blockOwnerDeletion": true, "controller": true, "kind": "Workspace", "name": "system-workspace", "uid": "6d535470-2592-4f3c-a155-eabc362c339d"], "resourceVersion": "7376520", "uid": "2b76e9b1-75f2-4a2e-a819-73b36aea188e" , "spec": "finalizers": [ ] , "status": "conditions": ["lastTransitionTime": "2022-01-05T08:05:47Z", "message": "All resources successfully discovered", "reason": "ResourcesDiscovered", "status": "False", "type": "NamespaceDeletionDiscoveryFailure" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "All legacy kube types successfully parsed", "reason": "ParsedGroupVersions", "status": "False", "type": "NamespaceDeletionGroupVersionParsingFailure" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "All content successfully deleted, may be waiting on finalization", "reason": "ContentDeleted", "status": "False", "type": "NamespaceDeletionContentFailure" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "Some resources are remaining: fluentbits.logging.kubesphere.io has 1 resource instances", "reason": "SomeResourcesRemain", "status": "True", "type": "NamespaceContentRemaining" ,"lastTransitionTime": "2022-01-05T08:05:47Z", "message": "Some content in the namespace has finalizers remaining: fluentbit.logging.kubesphere.io in 1 resource instances", "reason": "SomeFinalizersRemain", "status": "True", "type": "NamespaceFinalizersRemaining"], "phase": "Terminating"

执行清理命令
现在我们只需要一条命令就可以彻底删除这个 Namespace

kubectl replace --raw "/api/v1/namespaces/kubesphere-logging-system/finalize" -f ./kubesphere-logging-system.json

执行完以后，你需要等待一会
再次执行命令检查 namespaces

kubectl replace --raw "/api/v1/namespaces/kubesphere-logging-system/finalize" -f ./kubesphere-logging-system.json

最后的检查

kubectl getnskubesphere-logging-system Error from server (NotFound): namespaces "kubesphere-logging-system" not found[root@ip-10-0-100-206 ~]# kubectl getns NAMESTATUSAGE defaultActive23d kubesphere-controls-systemActive9d kubesphere-devops-systemActive9d kubesphere-devops-workerActive16h kubesphere-monitoring-federatedActive9d kubesphere-monitoring-systemActive9d kubesphere-sample-devActive8d kubesphere-systemActive9d

在此查看的时候，它已经不存在了。
