强制删除namespace

发布时间 2023-07-25 12:56:35作者: Chuyio

之前部署过一套监控

因为是本地测试环境，资源不太够，想着进行删除命名空间monitoring

[root@k8s-master01 ]# kubectl delete ns monitoring
namespace "monitoring" deleted
^C
[root@k8s-master01 ]# kubectl delete ns monitoring
namespace "monitoring" deleted
^C
[root@k8s-master01 ]# kubectl delete ns monitoring --force
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.
namespace "monitoring" force deleted
^C

一直删除不掉

解决办法

强制删除

[root@k8s-master01 ~]# kubectl get namespace monitoring -o json > monitoring.json

删除这几行

删除后

启动 运行kube-proxy

[root@k8s-master01 sonarqube]# kubectl proxy
Starting to serve on 127.0.0.1:8001
窗口不能关闭

通过API执行强制删除操作

[root@k8s-master01 ~]# curl -k -H "Content-Type: application/json" -X PUT --data-binary @monitoring.json http://127.0.0.1:8001/api/v1/namespaces/monitoring/finalize
{

    "name": "monitoring",

    }
  },
  "spec": {},
  "status": {
    "phase": "Terminating",
    "conditions": [
      {
        "type": "NamespaceDeletionDiscoveryFailure",
        "status": "True",

        "message": "Discovery failed for some groups, 1 failing: unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: the server is currently unable to handle the request"
      },
      {
        "type": "NamespaceDeletionGroupVersionParsingFailure",
        "status": "False",
        "lastTransitionTime": "2023-07-24T16:45:43Z",
        "reason": "ParsedGroupVersions",
        "message": "All legacy kube types successfully parsed"
      },
      {
        "type": "NamespaceDeletionContentFailure",
        "status": "False",
        "lastTransitionTime": "2023-07-24T16:45:43Z",
        "reason": "ContentDeleted",
        "message": "All content successfully deleted, may be waiting on finalization"
      },
      {
        "type": "NamespaceContentRemaining",
        "status": "False",
        "lastTransitionTime": "2023-07-24T16:45:52Z",
        "reason": "ContentRemoved",
        "message": "All content successfully removed"
      },
      {
        "type": "NamespaceFinalizersRemaining",
        "status": "False",
        "lastTransitionTime": "2023-07-24T16:45:43Z",
        "reason": "ContentHasNoFinalizers",
        "message": "All content-preserving finalizers finished"
      }
    ]
  }
}

再次删除测试
[root@k8s-master01 sonarqube]# kubectl delete ns monitoring 
Error from server (NotFound): namespaces "monitoring" not found

可以看到已经进行删除
[root@k8s-master01 sonarqube]# kubectl get ns -A | grep monitoring
[root@k8s-master01 sonarqube]#
