實跑撞到:這台裝的 wrangler 4.100.0 的 `kv key delete` 沒有 --force,帶了就直接 「Unknown argument: force」失敗。central-apply 兩個通道各撞一次才發現。 拿掉 --force 後在真實 youlin 帳號實測:central-apply 兩個通道(prod INSTALLER_KV + staging PEER_INSTALLER_KV)的 deployed:<accountId>: 紀錄都刪除成功,central-plan 複驗兩邊皆印「沒有殘留紀錄」。這是 Arcrun#120 死結修復鏈路的必要一步。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

/**
|
||
* teardown-instance.mjs — 把一個 Cloudflare 帳號上的 Arcrun self-hosted 安裝拆乾淨。
|
||
*
|
||
* 🔴 這是內部工具,不是產品(leo 2026-08-14:「簡單先做出 uninstaller⋯先產出你自己可用的
|
||
* 版本,在 youlin 使用,對外的後面提供」)。目的:讓「拆掉重裝」變成隨時做得到的事,
|
||
* 配套 D82 三步驗收(Arcrun#119/#120)——沒有拆的能力,「重裝從乾淨狀態開始」就永遠測不到。
|
||
*
|
||
* 背景(Arcrun#120):安裝器判斷 init/update 看的是**中心 KV** 的 `deployed:<accountId>:`,
|
||
* 不是「帳號上現在有什麼」。只清帳號上的 worker/KV/D1/Vectorize、漏清中心那筆 ⇒ 重裝被判定
|
||
* 「已經裝過」卡死。本工具因此分兩段:① 帳號側(Cloudflare 資源)② 中心側(安裝器的
|
||
* INSTALLER_KV/PEER_INSTALLER_KV `deployed:` 紀錄)——兩段都做才算「不再殘留」。
|
||
*
|
||
* 安全設計(這是刪除工具,寫錯會毀掉別人的東西):
|
||
* 1. 帳號白名單——只認 ALLOWED_ACCOUNT_IDS 裡的帳號,其餘一律拒絕執行。
|
||
* 2. 兩階段——預設 `plan`(唯讀,只印清單);要真的刪必須 `apply --yes`。
|
||
* 3. 歸屬判準——「這個帳號上的 worker 是不是這台 Arcrun 實例的」不是猜名字前綴,是
|
||
* 「這個 worker 名字有沒有出現在本 repo(matrix/arcrun)任何 wrangler*.toml 的
|
||
* `name = "..."`」。不認得的 worker 一律「不動、列出來讓人看」,不會被當成「安全,可刪」。
|
||
* 4. 共用資源保護——同一顆 KV/D1/Vectorize 若同時被「要刪的 worker」與「沒被列入要刪的
|
||
* worker」(不論是不認得的、還是被 --keep 排除的)綁著,一律排除、不刪、印警告。
|
||
* 這是為了 youlin 帳號上可能同時存在多台實例(例:一次性測試用的
|
||
* arcrun-cypher-executor-freshtest)而設——見下「已知限制」。
|
||
*
|
||
* 已知限制(誠實列,不要假裝這個判準萬能):
|
||
* - 判準是「repo 認不認得這個 worker 名字」,不是「這個 worker 屬於哪一台實例」。同帳號上
|
||
* 兩台同名慣例的實例(理論上不該發生,因為 worker 名字是全帳號唯一)用這個判準分不出來;
|
||
* 能分的是「已知元件 vs 陌生 worker」以及「資源有沒有被別的 worker 共用」。
|
||
* - `--keep <name,...>` 需要呼叫者自己知道帳號上有哪些 worker 該排除(本工具不會自動偵測
|
||
* 「這個 worker 是不是正在被別人使用」——那是 main/coordinator 層級的協調,不是機器能判斷的)。
|
||
* - 中心 KV 清理走 `wrangler kv key`,用的是本機既有的 wrangler OAuth 登入態(不是 CF API
|
||
* token),因為 INSTALLER_KV 住在另一個帳號(uncle6,官方安裝器所在),本工具沒有那把帳號
|
||
* 的 API token。呼叫前務必 `npx wrangler whoami` 確認登入態是 uncle6,不是別的帳號。
|
||
*
|
||
* 用法:
|
||
* node scripts/teardown-instance.mjs plan --account-id <id> --api-token <token> [--keep w1,w2]
|
||
* node scripts/teardown-instance.mjs apply --account-id <id> --api-token <token> [--keep w1,w2] --yes
|
||
* node scripts/teardown-instance.mjs central-plan --account-id <id>
|
||
* node scripts/teardown-instance.mjs central-apply --account-id <id> --yes
