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：
代码语言：javascript复制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
代码语言：javascript复制# 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
代码语言：javascript复制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。
代码语言：javascript复制vi kubesphere-system.json将
代码语言：javascript复制"spec": { "finalizers": [ "kubernetes"
]
},更改为：
代码语言：javascript复制"spec": {
},新开一个窗口运行kubectl proxy跑一个API代理在本地的8081端口
代码语言：javascript复制# kubectl proxy --port=8081
Starting to serve on 127.0.0.1:8081最后运行curl命令进行删除
代码语言：javascript复制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：
代码语言：javascript复制{

"lastTransitionTime": "2020-07-09T02:09:47Z",

}
]
}
}再次查看命名空间
代码语言：javascript复制# 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。
