CI/CD流程最佳实践

  • 🎯 分支策略:main分支自动部署生产,develop分支部署测试环境
  • 🎯 质量门禁:代码检查、测试通过才能部署
  • 🎯 环境隔离:开发、测试、生产环境完全隔离
  • 🎯 回滚机制:支持快速回滚到上一个稳定版本

容器化部署

# 🎉 前端应用Docker配置
# 多阶段构建Dockerfile
FROM node:18-alpine AS builder

WORKDIR /app

# 复制package文件并安装依赖

# 生产环境镜像
FROM nginx:alpine

# 复制自定义nginx配置
COPY nginx.conf /etc/nginx/nginx.conf

# 复制构建产物

🔍 常见问题FAQ

Q1: CI/CD流程搭建的优先级如何安排?

A: 建议顺序:代码检查→自动化测试→自动化构建→自动化部署→监控告警。先保证代码质量,再实现自动化部署。

Q2: Docker容器化部署的性能开销大吗?

A: 容器化的性能开销很小(通常<5%),但带来的环境一致性和部署便利性收益远大于性能开销。

Q3: 前端应用需要多复杂的监控系统?

A: 根据项目规模选择:小项目使用简单的错误监控,大项目建立完整的性能监控、错误追踪、用户行为分析体系。

Q4: 如何选择云服务提供商?

A: 考虑因素:成本、性能、服务质量、技术支持、数据安全。国内项目优先考虑阿里云、腾讯云,国际项目考虑AWS、Azure。

Q5: 前端应用的备份策略如何制定?

A: 代码备份依赖Git,构建产物备份到云存储,数据库定期备份,配置文件版本化管理。制定灾难恢复预案。
