一、问题提出
在使用 KubeSphere 的时候发现有一个日志服务KubeSphere Logging System，它被创建命名空间为kubesphere-logging-system下。当我们不想使用它，需要删除它时，确一直在 Terminating中，怎么也删除不掉。
kubectl delete ns kubesphere-logging-system --force --grace-period=0
二、删除方法
1，获取kubesphere-logging-syste的详细信息json文件
首先 通过以下命令获取 namespace 的详情信息并转为 json。
kubectl get namespace kubesphere-logging-system -o json > kubesphere-logging-system.json
2，编辑kubesphere-logging-system.json
vim kubesphere-logging-system.json
{ "apiVersion": "v1", "kind": "Namespace", "metadata": { "creationTimestamp": "2023-12-24T23:13:34Z", "deletionTimestamp": "2023-12-27T07:49:27Z", "labels": { "kubesphere.io/namespace": "kubesphere-logging-system", "kubesphere.io/workspace": "system-workspace" }, "name": "kubesphere-logging-system", "resourceVersion": "2878899", "selfLink": "/api/v1/namespaces/kubesphere-logging-system", "uid": "dd01ee56-2dee-40ba-b63e-5fc71e27507b" }, "spec": { "finalizers": [ "kubernetes" # 将此行删除 ] }, "status": { "conditions": [ { "lastTransitionTime": "2023-12-27T07:49:35Z", "message": "All resources successfully discovered", "reason": "ResourcesDiscovered", "status": "False", "type": "NamespaceDeletionDiscoveryFailure" }, { "lastTransitionTime": "2023-12-27T07:49:35Z", "message": "All legacy kube types successfully parsed", "reason": "ParsedGroupVersions", "status": "False", "type": "NamespaceDeletionGroupVersionParsingFailure" }, { "lastTransitionTime": "2023-12-27T08:47:05Z", "message": "All content successfully deleted, may be waiting on finalization", "reason": "ContentDeleted", "status": "False", "type": "NamespaceDeletionContentFailure" }, { "lastTransitionTime": "2023-12-27T07:49:35Z", "message": "Some resources are remaining: exporters.events.kubesphere.io has 1 resource instances, fluentbits.logging.kubesphere.io has 1 resource instances, rulers.events.kubesphere.io has 1 resource instances", "reason": "SomeResourcesRemain", "status": "True", "type": "NamespaceContentRemaining" }, { "lastTransitionTime": "2023-12-27T07:49:35Z", "message": "Some content in the namespace has finalizers remaining: exporters.finalizer.events.kubesphere.io in 1 resource instances, fluentbit.logging.kubesphere.io in 1 resource instances, rulers.finalizer.events.kubesphere.io in 1 resource instances", "reason": "SomeFinalizersRemain", "status": "True", "type": "NamespaceFinalizersRemaining" } ], "phase": "Terminating" } }
找到 spec 将 finalizers 下的 kubernetes 删除。
3，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
三、检查结果
查看namespace kubesphere-logging-system，
kubectl get ns kubesphere-logging-system
已经找不到命名空间kubesphere-logging-system了。
查看所有命名空间：
kubectl get ns
再次查看的时候，它已经不存在了！！
