当我们删除namespace的时候，经常会出现状态为Terminating，我们可以使用下面的脚本进行处理，从而减少ns 出现Terminating夯住的情况

脚本内容如下

<span>[</span>
<span>root@k8s</span>
<span>-</span>
<span>01</span>
<span> </span>
<span>~]#</span>
<span> cat kubedel</span>
<span>.</span>
<span>sh</span>
<span>#!/bin/bash</span>

<span># 获取要删除的 namespace 名称</span>
<span>NAMESPACE</span>
<span>=</span>
<span>"$1"</span>

<span># 如果没有传入参数，提示用户传入 namespace 名称</span>
<span>if</span>
<span> </span>
<span>[</span>
<span> </span>
<span>-</span>
<span>z </span>
<span>"$NAMESPACE"</span>
<span> </span>
<span>]</span>
<span>then</span>
<span>    echo </span>
<span>"请传入要删除的 namespace 名称："</span>
<span>    read NAMESPACE</span>
<span>fi</span>

<span># 提示用户 namespace 名称</span>
<span>echo </span>
<span>"您将要删除的 namespace 名称是：$NAMESPACE"</span>

<span># 使用 kubectl 命令获取 namespace 对应的 JSON 格式，再用 jq 工具修改 namespace 的 spec 属性，并将修改后的 JSON 数据保存到 temp.json 文件中</span>
<span>kubectl </span>
<span>get</span>
<span> </span>
<span>namespace</span>
<span> </span>
<span>"$NAMESPACE"</span>
<span> </span>
<span>-</span>
<span>o json </span>
<span>|</span>
<span> jq </span>
<span>'.spec = {"finalizers":[]}'</span>
<span> </span>
<span>></span>
<span> temp</span>
<span>.</span>
<span>json</span>

<span># 使用 curl 命令发送 PUT 请求，删除指定的 namespace</span>
<span>curl </span>
<span>-</span>
<span>k </span>
<span>-</span>
<span>H </span>
<span>"Content-Type: application/json"</span>
<span> </span>
<span>-</span>
<span>X PUT </span>
<span>--</span>
<span>data</span>
<span>-</span>
<span>binary </span>
<span>@temp</span>
<span>.</span>
<span>json </span>
<span>"127.0.0.1:8001/api/v1/namespaces/$NAMESPACE/finalize"</span>

<span># 检查是否删除成功，输出成功或失败信息</span>
<span>if</span>
<span> kubectl </span>
<span>get</span>
<span> </span>
<span>namespace</span>
<span> </span>
<span>"$NAMESPACE"</span>
<span> </span>
<span>></span>
<span>/dev/</span>
<span>null</span>
<span> </span>
<span>2</span>
<span>>&</span>
<span>1</span>
<span>then</span>
<span>    echo </span>
<span>"删除 namespace 成功"</span>
<span>else</span>
<span>    echo </span>
<span>"删除 namespace 失败"</span>
<span>fi</span>
