k8s namespace 一直处于 Terminating 状态的解决方法

• 以下的 tool 为 Terminating 状态的 namespace，下面相关的一些操作记得将 tool 修改成自己的 namespace 名称

json 格式导出 namespace 信息

k get ns tool -o json > tool.json

修改 json 文件

将 spec 和 status 下面的内容清空，将 metadata 字段花括号结尾的逗号去掉，保留完整的 json 格式

以下是修改过后的样式 [ 提供参考的，用来和原始 json 做对比，好增加理解 ]

{
    "apiVersion": "v1",
    "kind": "Namespace",
    "metadata": {
        "annotations": {
            "applicationCnName": "tool",
            "kubernetes.customized/bocloud_env_id": "3",
            "kubernetes.customized/bocloud_partition_id": "172",
            "kubernetes.customized/project_creator": "7",
            "kubernetes.customized/project_id": "10",
            "kubernetes.customized/tree_application_id": "10"
        },
        "creationTimestamp": "2022-10-18T06:38:25Z",
        "deletionTimestamp": "2022-10-20T02:34:18Z",
        "labels": {
            "app": "tool"
        },
        "name": "tool",
        "resourceVersion": "1011030",
        "selfLink": "/api/v1/namespaces/tool",

    }
}

开启 proxy 服务

这个时候要新打开一个终端，开启的 proxy 服务不是后台运行的，会占用一个终端

kubectl proxy

开启后会返回如下的内容

Starting to serve on 127.0.0.1:8001

调用接口删除 namespace

在另一个可以操作命令的终端，执行下面的 curl 命令

• tool.json - 记得修改成自己的文件名称
• tool/finalize - 里面的 tool 修改成自己的 namespace 名称

curl -k -H "Content-Type: application/json" \
-X PUT --data-binary @tool.json \
http://127.0.0.1:8001/api/v1/namespaces/tool/finalize

通过 kubectl 命令查看 namespace 是否还存在
