关于

本文探讨了如何使用 Google Cloud Functions 在三层架构中处理数据。该解决方案通过 Google Composer 进行编排，并使用 GitHub Actions 实现自动部署。我们将逐步介绍所使用的工具、部署过程和管道步骤，为构建基于云的端到端数据管道提供清晰的指南。

使用的工具

  1. Google Cloud Platform (GCP)： 主要云环境。
  2. 云存储：用于跨不同层（铜牌、银牌、金牌）存储输入和处理的数据。
  3. 云函数： 负责每一层数据处理的无服务器函数。
  4. Google Composer：基于 Apache Airflow 的编排工具，用于安排和管理工作流程。
  5. GitHub Actions： 用于部署和管理管道基础设施的自动化工具。

部署流程

先决条件

在设置项目之前，请确保您具备以下条件：

  1. GCP 帐户：已启用结算功能的 Google Cloud 帐户。
  2. DevOps 服务帐户：具有在 GCP 中部署资源所需权限的服务帐户。
  3. GitHub 中的机密：将 GCP 服务帐户凭据、项目 ID 和存储桶名称作为机密存储在 GitHub 中，以便安全访问。

GitHub Actions 的秘密

要安全地访问您的 GCP 项目和资源，请在 GitHub Actions 中设置以下机密：

  • BUCKET_DATALAKE：用于数据湖的 Cloud Storage 存储桶。
  • GCP_DEVOPS_SA_KEY：JSON 格式的服务帐户密钥。
  • PROJECT_ID：您的 GCP 项目 ID。
  • REGION_PROJECT_ID：部署您的 GCP 项目的区域。

要创建新的秘密： 

1. In project repository, menu **Settings** 
2. **Security**, 
3. **Secrets and variables**,click in access **Action**
4. **New repository secret**, type a **name** and **value** for secret.

设置 DevOps 服务帐户

在 GCP 中创建一个具有 Cloud Functions、Composer、BigQuery 和 Cloud Storage 权限的服务帐号。授予必要的角色，例如：

  • 云函数管理员
  • 作曲家用户
  • BigQuery 数据编辑器
  • 存储对象管理

GitHub Actions 管道：步骤

管道自动化了整个部署过程，确保所有组件都正确设置。以下是 GitHub Actions 文件中关键作业的细分，每个作业负责部署的不同方面。

部署后创建的资源

部署过程完成后，将提供以下资源：

  1. 云存储桶：分为铜牌、银牌和金牌层。
  2. Cloud Functions：：负责跨三层处理数据。
  3. Composer 的服务帐户：：具有调用云函数的适当权限。
  4. BigQuery 数据集和表：为存储处理后的数据而创建的 DataFrame。
  5. Google Composer 环境：编排云函数并进行日常执行。
  6. Composer DAG：DAG 管理调用 Cloud Functions 和处理数据的工作流程。

结论

此解决方案演示了如何利用 Google Cloud Functions、Composer 和 BigQuery 创建强大的三层数据处理管道。使用 GitHub Actions 的自动化可确保平稳、可重复的部署过程，从而更轻松地大规模管理基于云的数据管道。
