使用 IAM 控管存取權

本頁說明如何使用 Identity and Access Management (IAM)，控管 AI Applications 資源的 Discovery Engine API 存取權和權限。

總覽

Google Cloud 提供 IAM，可讓您以更精細的方式授予使用者特定 Google Cloud 資源的存取權限，避免其他資源遭到未經授權者擅自存取。本頁面說明 AI 應用程式的 IAM 角色與權限。如需 IAM 的詳細說明，請參閱 IAM 說明文件。 Google Cloud

AI 應用程式提供了一組預先定義的角色，用意在幫助您控管對 AI 應用程式資源的存取權。如果預先定義的角色未提供您需要的權限集，您也可以建立自己的自訂角色。此外，您仍可使用舊版基本角色 (編輯者、檢視者與擁有者)，但這些角色無法提供與 AI 應用程式角色相同的完善控管能力。尤其基本角色提供的是跨 Google Cloud 的資源存取，而非僅限 AI 應用程式。詳情請參閱基本角色說明文件。

預先定義的角色

AI Applications 提供一些預先定義角色，可為主體提供更精細的權限。授予主體的角色用於控管主體能夠採取的動作。主體可以是個人、群組或服務帳戶。

您可以將多個角色授予相同的主體，只要您具備相關權限，隨時都能變更授予主體的角色。

注意： 如要建立應用程式及查看監控資料，您可能需要預先定義的 Discovery Engine 角色未包含的權限。舉例來說，您需要 monitoring.timeSeries.list 權限。如要取得這項權限，請要求專案管理員授予您監控檢視者 (roles/monitoring.viewer) 角色，以及下列其中一個角色。

權限範圍越廣的角色會包含定義較為狹隘的角色。舉例來說，Discovery Engine 編輯者角色包含 Discovery Engine 檢視者角色的所有權限，再加上 Discovery Engine 編輯者角色的額外權限。同樣地，Discovery Engine 管理員角色包含 Discovery Engine 編輯者角色的所有權限，以及其他權限。

基本角色 (擁有者、編輯者、檢視者) 提供跨 Google Cloud的權限。AI 應用程式的專屬角色僅提供 AI 應用程式權限，除了以下的 Google Cloud權限，這些權限為一般 Google Cloud 使用所需：

• resourcemanager.projects.get
• resourcemanager.projects.list
• serviceusage.services.list
• serviceusage.services.get

下表列出 AI 應用程式 IAM 角色，以及各角色具備的所有權限對應清單。
