5.2 容器启动失败

排查步骤：

六、最佳实践指南

6.1 生产环境检查清单

6.2 开发环境优化建议

• 使用绑定挂载实现代码热更新：volumes:
  – ./code:/app
• 启用开发配置：docker compose -f docker-compose.dev.yml up

七、总结与延伸

docker compose up 作为容器编排的核心命令，主要应用于：

进阶方向：

• 结合Docker Swarm实现集群部署
• 使用Profiles管理服务组合
• 集成监控系统(Prometheus)
• 实现自动扩缩容机制

通过掌握这些技巧，可以构建从开发到生产的完整容器化工作流，实现高效的云原生应用管理。
