从 GitLab CI 将应用程序部署到 App Engine 时权限被拒绝

Question

我在使用 GitLab CI 将 Python 3 应用程序自动部署到 App Engine 标准时遇到了问题。

出现以下错误：

DEBUG: (gcloud.app.deploy) Error Response: [7] Failed to create cloud build: Permission denied

service: api
runtime: python37

我启用了 App Engine Admin API 并为 GitLab CI 创建了一个具有以下角色的服务帐户：

• 应用引擎部署者
• App Engine 服务管理员
• 存储对象创建者
• 存储对象查看器

GitLab CI 变量 $PROJECT_ID 和 $SERVICE_ACCOUNT 已经分别填充了 GCP 项目 id 和服务账户的 key。

自己修好了：

我需要启用 Cloud Build API 并将 Cloud Build 服务帐户角色授予我的服务帐户。
