• json 格式導出 namespace 信息
• 修改 json 文件
• 開啟 proxy 服務
• 調用接口刪除 namespace

以下的 tool 為 Terminating 狀態(tài)的 namespace，下面相關的一些操作記得將 tool 修改成自己的 namespace 名稱

json 格式導出 namespace 信息

k get ns tool -o json > tool.json

修改 json 文件

將 spec 和 status 下面的內容清空，將 metadata 字段花括號結尾的逗號去掉，保留完整的 json 格式

以下是修改過后的樣式 [ 提供參考的，用來和原始 json 做對比，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",

        "deletionTimestamp": "2022-10-20T02:34:18Z",
        "labels": {
            "app": "tool"
        },
        "name": "tool",
        "resourceVersion": "1011030",
        "selfLink": "/api/v1/namespaces/tool",
        "uid": "79793f2c-5290-4225-938b-8ce9e639a38c"
    }
}

開啟 proxy 服務

這個時候要新打開一個終端，開啟的 proxy 服務不是后臺運行的，會占用一個終端

kubectl proxy

開啟后會返回如下的內容

Starting to serve on 127.0.0.1:8001

調用接口刪除 namespace

在另一個可以操作命令的終端，執(zhí)行下面的 curl 命令

• tool.json – 記得修改成自己的文件名稱
• tool/finalize – 里面的 tool 修改成自己的 namespace 名稱

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

通過 kubectl 命令查看 namespace 是否還存在
