Dataplex IAM 角色

Dataplex 定义了多个 Identity and Access Management (IAM) 角色。每个预定义角色都包含一组允许主账号执行特定操作的 IAM 权限。您可以使用 IAM 政策向主账号授予一个或多个 IAM 角色。

IAM 还提供创建自定义角色的功能。您可以创建自定义 IAM 角色，并为该角色分配一项或多项权限。然后，您可以将新创建的角色授予主账号。使用自定义角色可创建访问权限控制模型，该模型将直接映射到您的需求以及可用的预定义角色。

本文档介绍了与 Dataplex 相关的 IAM 角色。

如需详细了解 IAM 及其功能，请参阅 IAM 文档。

Dataplex 角色简介

Dataplex IAM 角色包含一个或多个权限。您可以向主账号授予角色，以允许他们对项目中的 Dataplex 资源执行操作。例如，Dataplex Viewer 角色包含 dataplex.*.get 和 dataplex.*.list 权限，这些权限允许用户获取和列出项目中的 Dataplex 资源。如需了解详情，请参阅 Dataplex 权限。

您可以将 Dataplex 角色应用于服务层次结构中的任何资源，包括项目、数据湖和数据区域。

基本角色

您可以使用 IAM Project 角色在项目级分配基本角色。以下是与 IAM 项目角色关联的权限列表：

项目角色	权限
Project Owner	拥有所有“项目修改者”权限，外加为项目管理访问控制的权限（获取/设置 IamPolicy）和设置项目结算的权限
Project Editor	拥有所有 Project Viewer 权限，外加可修改状态的操作（创建、删除、更新、使用）的所有项目权限
项目查看者	拥有不会修改状态的只读操作（获取、列出）的所有项目权限

Dataplex 的预定义角色

预定义角色包含执行任务或一组相关任务所需的权限。

注意 ：如果您使用的是 Data Catalog，则 Data Catalog 条目访问权限授予不会自动转移到 Dataplex Catalog 条目。您必须先明确授予对 Dataplex Catalog 条目的访问权限，然后才能使用这些条目。

请注意以下几点：

• Dataplex 管理员、Dataplex 编辑者和 Dataplex 查看者角色不提供对 Dataplex Catalog 资源的访问权限。
• 没有任何角色有权在系统定义的条目组（例如 @bigquery 和 @dataplex）中添加或删除 Dataplex Catalog 条目。
• Dataplex Entry Owner 角色包括以下权限：
  • 授予对与条目相关的操作的完全访问权限。
  • 授予添加某些系统方面类型（例如 Schema、Generic、Overview 和 Contacts）的方面权限。
  • 授予创建 GenericEntry 类型条目的权限。
  • 借助此角色，您可以创建具有条目类型和切面类型的条目，其中条目类型和切面类型与条目在同一项目中定义。否则，必须在定义条目类型和切面类型的项目中授予额外的 Dataplex 条目类型用户角色和 Dataplex 切面类型用户角色。
  • 使用 LookupEntry 方法或 SearchEntries 方法时，此角色不会授予读取通过 Dataplex 外部Google Cloud 资源（例如 BigQuery 条目）创建的条目的权限。如需读取这些条目，您必须获得对源系统资源的权限。或者，您也可以使用 GetEntry 方法，仅使用 Dataplex 条目所有者角色读取条目。
• 如需使用 SearchEntries 方法搜索条目，您必须在 API 请求中使用的项目中至少获得一个 Dataplex Catalog IAM 角色。系统会独立于所选项目检查搜索结果的权限。

下表列出了 Dataplex 预定义角色以及与每个角色关联的权限：

数据传承的预定义角色

如需访问任何 Dataplex Catalog 条目的谱系，您需要有权访问 Dataplex 中的相应条目。如需访问 Dataplex Catalog 条目，您需要在相应的系统资源上拥有查看者角色，或者在存储 Dataplex Catalog 条目的项目上拥有 Dataplex Catalog Viewer 角色 (roles/dataplex.catalogViewer)。本部分介绍了查看谱系所需的角色。

Lineage 查看者角色

借助 Data Lineage Viewer 角色 (roles/datalineage.viewer)，您可以在 Google Cloud 控制台中查看 Dataplex 谱系，并使用 Data Lineage API 读取谱系信息。给定进程的运行作业和事件都存储在与该进程相同的项目中。对于自动谱系，流程、运行作业和事件会存储在生成谱系的作业运行所在的项目中。例如，这可能是运行 BigQuery 作业的项目。

您需要拥有不同的角色才能查看素材资源之间的谱系以及素材资源的元数据。对于前者，您需要拥有数据传承查看器角色 (roles/datalineage.viewer)。对于后者，您需要拥有与访问 Dataplex 中的元数据条目所需的角色相同的角色。

用于查看两个资产之间沿袭关系的角色

如需查看资产之间的沿袭关系，您需要在以下项目中拥有 Data Lineage Viewer 角色 (roles/datalineage.viewer)：

• 您查看谱系的项目（称为活动项目），即 Google Cloud 控制台顶部下拉菜单中的项目，或发出 API 调用的项目。这通常是包含您将在 Dataplex Catalog 中创建的资源或使用 API 访问的其他系统的项目。 Google Cloud
• 记录谱系的项目（称为计算项目）。如前所述，谱系存储在执行相应流程的项目中。此项目可以不同于存储您要查看谱系的资源的项目。

如需详细了解如何授予角色，请参阅管理访问权限。 您也可以通过自定义角色或其他预定义角色来获取所需的权限。

根据用例，在文件夹级别或组织级别授予数据谱系查看者角色 (roles/datalineage.viewer)，以确保对谱系的访问权限（请参阅授予或撤消单个角色）。数据沿袭所需的角色只能通过 Google Cloud CLI 授予。

注意 ：如需查看 BigQuery 进程的 SQL 语句，您必须拥有相应作业的 bigquery.jobs.get 权限。如需查看 BigQuery 视图定义的 SQL 语句，您必须对相应视图拥有 bigquery.tables.get 权限。

查看沿袭时可查看资产元数据的角色

当资产的元数据存储在 Dataplex Catalog 中时，只有当您对相应的系统资源具有查看者角色，或者对存储 Dataplex Catalog 条目的项目具有 Dataplex Catalog Viewer 角色 (roles/dataplex.catalogViewer) 时，才能查看该元数据。您或许可以通过适当的查看者角色访问谱系图或列表中的素材资源，但无法访问这些素材资源之间的谱系。如果您在记录了沿袭的项目上没有 Data Lineage Viewer 角色 (roles/datalineage.viewer)，就会出现这种情况。在这种情况下，Data Lineage API 和 Google Cloud 控制台不会显示谱系，也不会返回错误，以防止泄露有关谱系存在的信息。因此，资产没有沿袭信息并不意味着该资产没有沿袭信息，而是表示您可能无权访问该沿袭信息。

注意： 如果某个资产位于您不是成员的组织中，数据传承可能无法检索该资产的元数据。

Data Lineage Events Producer 角色

借助 Data Lineage Events Producer 角色 (roles/datalineage.producer)，用户可以使用 Data Lineage API 手动记录谱系信息。

Data Lineage Editor 角色

借助“Data Lineage Editor”角色 (roles/datalineage.editor)，用户可以使用 Data Lineage API 手动修改谱系信息。

Data Lineage Administrator 角色

借助数据源流水线管理员角色 (roles/datalineage.admin)，用户可以执行本部分中列出的所有数据源流水线操作。

数据角色

Dataplex 定义了以下 IAM 角色，旨在应用于 Dataplex 管理的任何资源。如需详细了解与每个角色关联的权限，请参阅本文档的预定义角色部分。

数据角色	功能	理由
Dataplex Data Owner (roles/dataplex.dataOwner)	对托管资源的所有权限。以及对所有子资源的所有权限（无论资源类型如何）。	除了各种其他权限之外，数据所有者还可以更新资源元数据、授予更精细的权限（例如，对 BigQuery 数据集的子表授予权限），以及创建子资源。他们拥有资源的完整所有权。
Dataplex Data Reader (roles/dataplex.dataReader)	能够读取受管资源及其子资源中的数据。以及读取受管资源及其子资源的元数据的权限。	能够读取数据和元数据。
Dataplex Data Writer (roles/dataplex.dataWriter)	能够创建/更新/删除数据（而非元数据）。	启用核心 Dataplex 用户体验历程。
