# ./kubectl get namespaces --kubeconfig ./conf/kubeconfig
NAME              STATUS        AGE
default           Active        27h
istio-system      Terminating   20h
kube-node-lease   Active        27h
kube-public       Active        27h
kube-system       Active        27h

解决方法如下：

1

# kubectl get namespace istio-system -o json > tmp.json

先运行 kubectl get namespace istio-system -o json &gt; tmp.json，拿到当前 namespace 描述，然后打开 tmp.json ，删除其中的 spec 字段。

最后运行：

{
  "kind": "Namespace",

    "name": "istio-system",
    "selfLink": "/api/v1/namespaces/istio-system/finalize",
    "uid": "713e2935-41eb-4e8f-be52-3b43a7536b4f",
    "resourceVersion": "29523",

    "managedFields": [
      {
        "manager": "kubectl",
        "operation": "Update",
        "apiVersion": "v1",
        "time": "2020-09-08T11:18:34Z",
        "fieldsType": "FieldsV1",
        "fieldsV1": {"f:status":{"f:phase":{}}}
      }
    ]
  },
  "spec": {

  },
  "status": {
    "phase": "Terminating"
  }
}

至此，命名空间已经删除
