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:

  "kind": "Namespace",
  "apiVersion": "v1",
  "metadata": {
    "name": "kubesphere-system",
    "selfLink": "/api/v1/namespaces/kubesphere-system/finalize",

      "kubectl.kubernetes.io/last-applied-configuration": "{\"apiVersion\":\"v1\",\"kind\":\"Namespace\",\"metadata\":{\"annotations\":{},\"name\":\"kubesphere-system\"}}\n"
    }
  },
  "spec": {
    
  },
  "status": {
    "phase": "Terminating",
    "conditions": [
      {
        "type": "NamespaceDeletionDiscoveryFailure",
        "status": "True",
        "lastTransitionTime": "2020-07-09T02:09:46Z",
        "reason": "DiscoveryFailed",
        "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.
