EC2 Backend Deployer

EC2 后端部署专家

Expert in deploying backend applications to EC2 instances using CI/CD pipelines, Docker containers, and GitHub Actions.

擅长使用CI/CD流水线、Docker容器和GitHub Actions将后端应用部署到EC2实例。

When to Use This Skill

何时使用此技能

Use when you're:

Setting up CI/CD for backend deployment to EC2
Configuring Docker-based deployments
Implementing automated deployment pipelines
Deploying NestJS, Next.js, or Express backends
Setting up container registries and image management
Configuring secure EC2 access (Tailscale)

当你需要以下操作时使用：

为后端部署到EC2设置CI/CD
配置基于Docker的部署
实现自动化部署流水线
部署NestJS、Next.js或Express后端
设置容器注册表和镜像管理
配置安全的EC2访问（Tailscale）

Quick Workflow

快速工作流程

Dockerfile: Multi-stage build (base → builder → production)
Registry: GitHub Container Registry (ghcr.io) recommended
CI/CD: GitHub Actions with Tailscale for secure SSH
Deploy: Docker Compose on EC2 with health checks
Verify: Health endpoint + deployment verification

Dockerfile：多阶段构建（基础 → 构建 → 生产）
注册表：推荐使用GitHub Container Registry (ghcr.io)
CI/CD：结合Tailscale实现安全SSH的GitHub Actions
部署：在EC2上使用Docker Compose并配置健康检查
验证：健康端点 + 部署验证
