淘汰自訂映像檔

Linux Windows

Compute Engine 可讓您在映像檔上設定淘汰狀態，以淘汰您擁有的自訂映像檔。每一種淘汰狀態會引起不同的伺服器反應，協助您採用易管理的方法，為使用者淘汰不再支援的映像檔。您可以使用 Google Cloud 控制台、Google Cloud CLI 或 Compute Engine API 方法來淘汰映像檔。

淘汰狀態

支援的淘汰狀態如下：

ACTIVE：圖片有效，可正常使用。映像檔系列會指向系列中最新且有效的映像檔。
DEPRECATED：映像檔標示為已淘汰，但仍可用於建立 VM。您仍然可以建立此圖片的新連結。即使它是系列中最新的映像檔，映像檔系列也不再指向此映像檔。

如果您使用 Google Cloud CLI 透過已淘汰的映像檔建立 VM，要求會成功執行，但會顯示警告。
OBSOLETE：圖片已標示為過時，無法再使用。如果您嘗試在要求中使用此映像檔，系統會傳回錯誤訊息。仍然允許對於此映像檔的現有連結。
DELETED：這張圖片已刪除。如果您嘗試使用已刪除的圖片，系統會傳回錯誤訊息。

如要還原淘汰狀態 (再次啟用圖片)，請將淘汰狀態變更為 ACTIVE。

事前準備

參閱映像檔文件。
如果尚未設定驗證，請先完成設定。「驗證」是指驗證身分的程序，確認您有權存取 Google Cloud 服務和 API。如要從本機開發環境執行程式碼或範例，請選取下列其中一個選項，向 Compute Engine 進行驗證：

Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

淘汰自訂映像檔

主控台

前往 Google Cloud 控制台的「Images」(映像檔) 頁面。

前往「圖片」
找出要淘汰的映像檔，然後按一下「動作」。
選取「淘汰」。
選取「已淘汰」或「已過時」。如要進一步瞭解狀態，請參閱「淘汰狀態」。
選用：指定替代圖片。
按一下「淘汰映像檔」。

gcloud

使用 gcloud compute images deprecate 指令設定映像檔的淘汰狀態。

gcloud compute images deprecate IMAGE_NAME \
    --state STATE \
    --replacement REPLACEMENT

更改下列內容：

IMAGE_NAME：要淘汰的映像檔名稱
STATE：廢止狀態
REPLACEMENT：要用來取代淘汰映像檔的映像檔
