 ## Definition
-CI/CD (Continuous Integration/Continuous Delivery/Deployment) pipelines automate the process of building, testing, and deploying software changes.
+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。
 
-## Components
+## Core Components
 
-### Continuous Integration (CI)
-- Automated builds on code commits
-- Automated testing (unit, integration, e2e)
-- Code quality checks and linting
-- Artifact generation
+### 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
 
-### Continuous Delivery (CD)
-- Automated deployment to staging environments
-- Manual approval gates for production
-- Configuration management
+### 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
 
-### Continuous Deployment
-- Fully automated deployment to production
-- Feature flags for gradual rollout
-- Automated rollback capabilities
+### 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
-- **CI/CD Platforms**: Jenkins, GitLab CI, GitHub Actions, CircleCI, ArgoCD
-- **Build Tools**: Maven, Gradle, npm, Docker
-- **Testing**: JUnit, PyTest, Selenium, Playwright
+## 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
 
-## Best Practices
-1. Keep the pipeline fast (under 10 minutes)
-2. Fail fast — run fastest tests first
-3. Use meaningful commit messages and branch names
-4. Implement proper caching strategies
-5. Store build artifacts securely
-6. Enable parallel test execution

-## CI/CD Pipeline Across DevOps Maturity Levels
-
-| Maturity | Pipeline Maturity |
-|----------|------------------|
-| Phase 1 | No CI/CD — manual builds, manual testing, milestone-based releases |
-| Phase 2 | Basic version control, some automation for risk reduction, unit/integration/E2E tests |
-| Phase 3 | Automated infrastructure provisioning, security scans in CI, more frequent deployments |
-| Phase 4 | Continuous integration pipeline, immutable infrastructure managed through pipelines, performance testing |
-| Phase 5 | Zero human intervention, real-time data-driven decisions, multiple daily deployments |

+## 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
