配置对远程代码库上游的身份验证

本文档介绍了如何针对 Artifact Registry 远程代码库的上游来源进行身份验证。

本文档假设您已创建 Artifact Registry 远程代码库，并且拥有外部来源的账号。

如需详细了解远程代码库，请参阅远程代码库概览。

所需的角色

如需获得为远程代码库配置对上游来源的身份验证所需的权限，请让管理员向您授予项目的以下 IAM 角色：

如需详细了解如何授予角色，请参阅管理对项目、文件夹和组织的访问权限。

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。

预设上游来源

如需为预设的上游来源配置身份验证，请参阅以下针对每个上游的相应指南：

用户定义的上游来源

如需为用户定义的上游来源配置身份验证，请完成以下步骤。

将访问令牌保存在 Secret 中

  1. 在私有注册表中创建访问令牌。
  2. 在 Secret Manager 中创建 Secret。
  3. 将您的个人访问令牌保存为 Secret 版本。

向 Artifact Registry 服务账号授予对您的 Secret 的访问权限

Artifact Registry 服务代理在与 Google Cloud 服务交互时会代表 Artifact Registry 执行操作。如需允许服务代理使用存储在 Secret Manager 中的 Secret，您必须向服务代理授予查看 Secret 版本的权限。

服务代理标识符为：

service-PROJECT-NUMBER@gcp-sa-artifactregistry.iam.gserviceaccount.com

PROJECT-NUMBER 是 Google Cloud 运行 Artifact Registry 的项目的项目编号。

如需向 Artifact Registry 服务代理授予 Secret Manager Secret Accessor 角色，请执行以下操作：

控制台

  1. 前往 Google Cloud 控制台中的 Secret Manager 页面。

    转到 Secret Manager 页面

  2. 在 Secret Manager 页面上，点击 Secret 名称旁边的复选框。

  3. 如果面板尚未打开，请点击显示信息面板以打开面板。

  4. 在信息面板中，点击添加主账号。

  5. 在新主账号文本区域中，输入要添加的成员的电子邮件地址。

  6. 在选择角色下拉列表中，选择 Secret Manager，然后选择 Secret Manager Secret Accessor。

gcloud

$ gcloud secrets add-iam-policy-binding secret-id \
    --member="member" \
    --role="roles/secretmanager.secretAccessor"

其中，member 是 IAM 成员，例如用户、群组或服务账号。

向远程代码库添加上游凭据

如需使用上游来源凭据更新远程代码库，请执行以下操作：

控制台

  1. 在 Google Cloud 控制台中打开代码库页面。

    打开“代码库”页面

  2. 在代码库列表中，选择相应代码库，然后点击修改代码库。

  3. 在远程仓库身份验证模式部分中，更新或添加您的上游来源用户名和包含访问令牌的密钥。

gcloud CLI

如需使用上游来源凭据更新远程代码库，请运行以下命令：

gcloud artifacts repositories update REPOSITORY \
    --project=PROJECT_ID \
    --location=LOCATION \
    --remote-username=USERNAME \
    --remote-password-secret-version=projects/SECRET_PROJECT_ID/secrets/SECRET_ID/versions/SECRET_VERSION

替换以下内容：

  • 将 REPOSITORY 替换为 Artifact Registry 远程代码库的名称。
  • 将 PROJECT_ID 替换为您的 Google Cloud 项目 ID。
  • LOCATION 替换为代码库的单区域或多区域位置。如果您设置默认值，则可以省略此标志。如需查看受支持位置的列表，请运行命令 gcloud artifacts locations list。
  • 将 USERNAME 替换为您的上游来源用户名。
  • 将 SECRET_PROJECT_ID 替换为您在其中创建 Secret 的项目的项目 ID。
  • 将 SECRET_ID 替换为您为 Secret 指定的名称。
  • 将 SECRET_VERSION 替换为您保存访问令牌的 Secret 版本。

下次远程代码库向上游来源请求制品时，系统会使用您的凭据。
