## Definition
CI/CD 流水线CI/CD Pipeline是持续集成Continuous Integration和持续交付/部署Continuous Delivery/Deployment的自动化流程用于管理基础设施代码IaC的构建、测试和部署。在 Gruntwork Landing Zone 架构中,每个 Landing Zone 配置独立的 Jenkins 服务器和 CI/CD 流水线来自动化 Terraform 基础设施变更。
## Core Components
### CI持续集成
- **代码提交**:开发人员将特性分支代码推送到 GitHub 仓库
- **自动构建**Jenkins 触发 Terraform 初始化和格式化验证
- **自动测试**TerraTest 执行基础设施单元测试和集成测试
- **代码审查**Pull Request 必须通过审查才能合并到主分支
### CD持续交付/部署)
- **自动部署**合并到主分支后Jenkins 自动执行 Terraform Plan
- **审批流程**:变更需要人工审批后才执行 Apply
- **渐进式部署**:支持 Blue-Green 部署和 Canary Release 策略
### Infrastructure-Specific Considerations
- **状态管理**Terraform State 的锁定和远程存储(使用 S3 + DynamoDB
- **幂等性**Terraform 模块设计必须支持重复执行而不产生副作用
- **回滚机制**:通过 Terraform State 历史版本实现快速回滚
- **漂移检测**:定期运行 `terraform plan` 检测配置漂移
## Tools in Gruntwork Landing Zone Context
- **Jenkins**:核心 CI/CD 引擎,每个 Landing Zone 独立部署
- **Terraform**IaC 工具,定义和管理 AWS 资源
- **TerraTest**Go 语言编写的基础设施测试框架
- **GitHub**:代码仓库,支持特性分支和 Pull Request 工作流
## Git Workflow
- 特性分支开发:`feature/<description>`
- 通过 Pull Request 合并到主分支
- 必须经过代码审查和 CI 测试
- 合并后触发自动部署流水线
