title: "CTP Topic 32 Using Atlantis CICD for Infrastructure Deployments"

## Source File
|
||||
- [[Cloud & DevOps/Public-Cloud-Learning-Sessions/06_CI_CD_GitOps/ctp-topic-32-using-atlantis-cicd-for-infrastructure-deployments]]
|
||||
|
||||
## Summary(用中文描述)
|
||||
|
||||
### 核心主题
|
||||
Atlantis 作为 Terraform IaC 自动化工具,替代 Jenkins 用于 AWS Landing Zone 的基础设施部署流水线。
|
||||
|
||||
### 问题域
|
||||
当前 Jenkins 流水线面临两大核心痛点:
|
||||
- **速度慢**:初始化时间长、多次代码克隆、顺序测试、ECS Deployer 预配置导致整个流程极慢
|
||||
- **复杂度高**:持续叠加功能以覆盖更多场景和边缘用例,导致流水线脆弱且易漂移
|
||||
|
||||
### 方法/机制
|
||||
- **架构**:Atlantis 以单台 EC2 实例形式部署于每个 Landing Zone 的共享账户,通过 GitHub Enterprise Webhook 接收通知
|
||||
- **协作模型**:开发者直接在 GitHub Pull Request 上评论即可与 Atlantis 交互,无需单独账号和复杂集成
|
||||
- **跨账户访问**:通过在每个账户部署的 IAM 角色实现,支持简单和跨账户模块部署
|
||||
- **权限控制**:用户管理基于 GitHub 构建,构建日志以评论形式存储用于审计
|
||||
- **并行构建**:支持多模块 plan 和 apply 命令并发执行
|
||||
|
||||
### 结论/价值
|
||||
Atlantis 提供更好的协作模型、简化的网络架构(Jenkins 需要大量 VPC Endpoints)、代码与基础设施同步更新(merge 前即应用变更),是替换 Jenkins 的理想方案。
|
||||
|
||||
## Key Claims(用中文描述)
|
||||
|
||||
- Atlantis 团队通过在 PR 上评论即可完成 plan/apply,无需独立的 Jenkins 账号和集成
|
||||
- Atlantis 在代码 merge 前即执行变更,确保代码始终与基础设施同步
|
||||
- Atlantis 锁定机制防止多 PR 同时对同一模块执行 plan 产生冲突
|
||||
- Atlantis 通过 Webhook 接收 GitHub 通知,服务账号负责与 GitHub 交互(评论、合并、关闭 PR)
|
||||
|
||||
## Key Quotes
|
||||
|
||||
> "The current pipeline is practically very slow due to significant initialization time, multiple code cloning, sequential testing, and ECS deployer provisioning." — 当前 Jenkins 流水线的性能痛点
|
||||
|
||||
> "Atlantis applies changes before merging, ensuring code in sync with infrastructure." — Atlantis 的核心价值主张
|
||||
|
||||
> "When a plan is run, the directory of each module is locked until the pull request that has this folder locked is merged or closed, or the plan is manually discarded." — Atlantis 锁定机制
|
||||
|
||||
## Key Concepts
|
||||
|
||||
- [[Infrastructure-as-Code]]:通过 Terraform 代码声明式管理 AWS 基础设施,Atlantis 是其 CI/CD 执行层
|
||||
- [[GitOps]]:以 Git 为单一事实来源,通过 PR 协作和 Atlantis 自动化 apply 实现 GitOps 工作流
|
||||
- [[CI/CD Pipeline]]:持续集成/持续部署流水线,Atlantis 替代传统 Jenkins 流水线用于 IaC 场景
|
||||
- [[Terraform]]:HashiCorp 的基础设施即代码工具,Atlantis 的核心执行对象
|
||||
|
||||
## Key Entities
|
||||
|
||||
- [[Terraform]]:Atlantis 管理的基础设施即代码工具,替代手动控制台操作
|
||||
- [[Jenkins]]:被 Atlantis 替代的现有 CI/CD 系统,存在初始化慢和架构复杂的问题
|
||||
- [[GitHub Enterprise]]:Atlantis 的事件来源,通过 Webhook 通知 Atlantis 执行 plan/apply

|
||||
## Contradictions
|
||||
|
||||
- 与 [[ctp-topic-39-implementing-eks-in-the-aws-lab-landing-zone]]:
|
||||
- **冲突点**:EKS 部署是否支持 Atlantis
|
||||
- **当前观点(Topic 39)**:Atlantis 当前不支持 EKS 部署,需通过 Jenkins + Terragrunt 模块替代
|
||||
- **对方观点(Topic 32)**:Atlantis 可替代 Jenkins 用于所有 Terraform IaC 部署
|
||||
- **分析**:两者描述的语境不同——Topic 39 聚焦特定 EKS 场景下的实践经验,Topic 32 描述 Atlantis 整体优势。可能 Atlantis 在某些复杂场景(如 EKS 特定依赖)下存在限制,需进一步验证
