配置针对 Python 软件包索引 (PyPI) 的远程仓库身份验证

本文档介绍了如何为 Artifact Registry 远程代码库配置向 Python 软件包索引 (PyPI) 上游代码库进行的身份验证。

本文档假定您已创建 Artifact Registry Python 远程代码库和 PyPI 帐号。

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

如需获取为远程代码库配置 PyPI 身份验证所需的权限，请让管理员授予您项目的以下 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。

创建 PyPI API 令牌

  1. 登录 PyPI。
  2. 创建 API 令牌。

将您的 API 令牌保存为密钥版本

  1. 在 Secret Manager 中创建 Secret。
  2. 将您的 PyPI API 令牌保存为 Secret 版本。

向 Artifact Registry 服务帐号授予对您的密钥的访问权限

Artifact Registry 服务代理是由 Google 代管式服务帐号，在与 Google Cloud 服务交互时代表 Artifact Registry。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您的 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 是运行 Artifact Registry 的 Google Cloud 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. 转到 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。

API

注意：与其他示例不同，它将替换整个 IAM 政策。

$ curl "https://secretmanager.googleapis.com/v1/projects/project-id/secrets/secret-id:setIamPolicy" \
    --request "POST" \
    --header "authorization: Bearer $(gcloud auth print-access-token)" \
    --header "content-type: application/json" \
    --data "{\"policy\": {\"bindings\": [{\"members\": [\"member\"], \"role\": \"roles/secretmanager.secretAccessor\"}]}}"

将 PyPI 凭据添加到远程代码库

如需使用 PyPI 凭据更新远程代码库，请执行以下操作：

控制台

  1. 打开 Google Cloud 控制台中的制品库页面。

    打开“代码库”页面

  2. 在代码库列表中，选择代码库，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 PYPI 用户名 __token__ 和包含 PyPI API 令牌的 Secret 版本。

gcloud CLI

如需使用 PyPI 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=__token__ \
    --remote-password-secret-version=projects/SECRET_PROJECT_ID/secrets/SECRET_ID/versions/SECRET_VERSION

替换以下内容：

  • 将 REPOSITORY 替换为您的 Artifact Registry 远程代码库的名称。
  • 将 PROJECT_ID 替换为 Google Cloud 项目 ID。
  • 将 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。
  • USERNAME 替换为您的 PyPI 用户名。
  • 将 SECRET_PROJECT_ID 替换为您在其中创建了 Secret 的项目的 ID。
  • SECRET_ID 替换为您提供的 Secret 名称。
  • 将 SECRET_VERSION 替换为您保存 PyPI API 令牌的密钥版本。

远程仓库下次从上游来源发送请求以获取工件时，将使用您的凭据。
