使用 IAM 进行访问权限控制

本页面介绍如何使用 Identity and Access Management (IAM) 控制对 Vertex AI Search 资源的 Discovery Engine API 访问权限和权限。

概览

Google Cloud 提供 IAM，可让您授予对特定 Google Cloud 资源的更精细访问权限，并防止对其他资源进行不必要的访问。本页面介绍了 Vertex AI Search IAM 角色和权限。如需详细了解 Google CloudIAM，请参阅 IAM 文档。

Vertex AI Search 提供了一组预定义角色，旨在帮助您控制对 Vertex AI Search 资源的访问权限。如果预定义角色无法提供您所需的权限集，您还可以创建自己的自定义角色。此外，基本角色（Editor、Viewer 和 Owner）仍可供您使用，但这些角色提供的控制不如 Vertex AI Search 角色那样精细。具体而言，基本角色提供的是对整个 Google Cloud 资源的访问权限，而不仅仅是对 Vertex AI Search 的访问权限。如需了解详情，请参阅基本角色文档。

预定义角色

Vertex AI Search 提供了一些预定义角色，可供您用来为主账号提供更精细的权限。您授予主账号的角色决定了主账号可以执行的操作。主账号可以是个人、群组或服务账号。

如果您拥有相关权限，可向同一主账号授予多个角色，还可随时更改授予主账号的角色。

注意： 如需创建应用并查看其监控数据，您可能需要预定义的 Discovery Engine 角色中未包含的权限。例如，需要 monitoring.timeSeries.list 权限。如需获得此权限，请考虑让项目管理员为您授予 Monitoring Viewer (roles/monitoring.viewer) 角色以及下列角色之一。

权限范围较广的角色拥有权限范围较窄的角色的所有权限。例如，Discovery Engine 编辑者角色包含 Discovery Engine 查看者角色的所有权限，还在其基础上添加了一些额外的 Discovery Engine 编辑者角色权限。同样，Discovery Engine Admin 角色不但拥有 Discovery Engine Editor 角色的所有权限，而且还添加了一些专有权限。

基本角色（Owner、Editor、Viewer）提供对整个 Google Cloud的权限。Vertex AI Search 特有的角色仅提供 Vertex AI Search 权限，但以下 Google Cloud权限除外，因为这些是 Google Cloud 常规使用所需的权限：

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

下表列出了 Vertex AI Search IAM 角色以及每个角色包含的所有权限。
