json 格式导出 namespace 信息修改 json 文件开启 proxy 服务调用接口删除 namespace
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
复制代码
修改 json 文件
- {

- }
复制代码
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”,
- “uid”: “79793f2c-5290-4225-938b-8ce9e639a38c”
- }
- }

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
复制代码
开启后会返回如下的内容
- Starting to serve on 127.0.0.1:8001
复制代码
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
复制代码
通过 kubectl 命令查看 namespace 是否还存在
