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",

},
{
"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!!
