k8s删除Terminating状态的命名空间

# 一、概述 #

最近部署kubesphere时，使用kubectl  delete -f xxx.yaml，再次执行 kubectl apply -f xxx.yaml，提示：

Error from server (Forbidden): error when creating "kubesphere-complete-setup.yaml": configmaps "ks-installer" is forbidden: unable to create new content in namespace kubesphere-system because it is being terminated
    Error from server (Forbidden): error when creating "kubesphere-complete-setup.yaml": serviceaccounts "ks-installer" is forbidden: unable to create new content in namespace kubesphere-system because it is being terminated
    Error from server (Forbidden): error when creating "kubesphere-complete-setup.yaml": deployments.apps "ks-installer" is forbidden: unable to create new content in namespace kubesphere-system because it is being terminated

查看命名空间

# kubectl  get ns 
    NAME                STATUS        AGE
    default             Active        15h
    kube-node-lease     Active        15h
    kube-public         Active        15h
    kube-system         Active        15h
    kubesphere-system   Terminating   28m

发现kubesphere-system一直处于Terminating 状态。无法删除命名空间！！

# 二、解决方法 #

查看kubesphere-system的namespace描述

kubectl get ns kubesphere-system  -o json > kubesphere-system.json

编辑json文件，删除spec字段的内存，因为k8s集群时需要认证的。

vi kubesphere-system.json

将

"spec": {
            "finalizers": [
                "kubernetes"
            ]
        },

更改为：

"spec": {
        
      },

新开一个窗口运行kubectl proxy跑一个API代理在本地的8081端口

# kubectl proxy --port=8081
    Starting to serve on 127.0.0.1:8081

最后运行curl命令进行删除

curl -k -H "Content-Type:application/json" -X PUT --data-binary @kubesphere-system.json http://127.0.0.1:8081/api/v1/namespaces/kubesphere-system/finalize

**注意：命令中的kubesphere-system就是命名空间。**

输出：

      "apiVersion": "v1",

            "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": "2020-07-09T02:09:47Z",
            "reason": "ParsedGroupVersions",
            "message": "All legacy kube types successfully parsed"
          },
          {
            "type": "NamespaceDeletionContentFailure",
            "status": "False",
            "lastTransitionTime": "2020-07-09T02:09:47Z",
            "reason": "ContentDeleted",
            "message": "All content successfully deleted"
          }
        ]
      }
    }

再次查看命名空间

# kubectl get ns
    NAME              STATUS   AGE
    default           Active   15h
    kube-node-lease   Active   15h
    kube-public       Active   15h
    kube-system       Active   15h

发现kubesphere-system命名空间已经消失了。

最后再次执行 kubectl apply -f xxx.yaml，就正常了。
