搭配 Batch 集區使用延伸模組

發行項
10/16/2024

延伸模組是小型應用程式，可協助在 Batch 計算節點上進行佈建後的設定及安裝。您可以選取 Azure Batch 允許的任何延伸模組，並在加以佈建時將其安裝在計算節點上。之後，延伸模組就可以執行預定的作業。

您可以檢查您使用之延伸模組的即時狀態，並擷取其所傳回的資訊，以執行任何偵測、更正或診斷功能。

必要條件

具有延伸模組的集區必須使用虛擬機器設定 (部分機器翻譯)。
CustomScript 延伸模組類型會保留給 Azure Batch 服務，且無法覆寫。
某些延伸模組可能需要在計算節點的內容中存取集區層級受控識別，才能正常運作。請參閱在 Batch 集區中設定受控識別，以確認是否適用於延伸模組。

提示

延伸模組無法新增至現有的集區。必須重新建立集區才能新增、移除或更新延伸模組。

支援的擴充功能

建立 Batch 集區時，目前可以安裝下列延伸模組：

您可以建立支援要求，以要求支援其他發行者和/或延伸模組類型。

建立具有延伸模組的集區

下列範例會建立使用 Azure Key Vault 延伸模組的 Linux/Windows 節點 Batch 集區。

針對 Key Vault 延伸模組進行疑難排解

如果 Key Vault 延伸模組的設定不正確，則計算節點可能處於可用狀態。若要針對 Key Vault 延伸模組失敗進行疑難排解，您可以暫時將 requireInitialSync 設定為 false 並重新部署您的集區，然後計算節點會處於閒置狀態，您可登入計算節點來檢查 KeyVault 延伸模組記錄是否有錯誤並修正設定問題。如需詳細資訊，請瀏覽下列 Key Vault 延伸模組文件連結。
