我们使用前面《SpringCloudAlibaba注册中心与配置中心之利器Nacos实战与源码分析（中）》的两个微服务示例，分别是库存微服务和订单微服务，基于Nacos注册中心和配置中心的使用，前面Nacos我们已基于dock-compose方式部署，我们增加配置数据，这里我们暂时也不把数据打包进去，各位可以直接将容器以dokcer export方式导入为镜像，微服务使用订单、库存MySQL数据库暂时也不单独做成镜像，各位可以做成SQL脚本执行导入方式。
- docker目录docker compose编排脚本目录
- bin目录：包含初始化脚本、启动脚本、停止脚本、更新脚本
- env目录：存在为微服务环境变量
- yaml目录：存在全局环境脚本变量、微服务docker-compose脚本
- 库存微服务
- bin目录：存在微服务启动脚本
- conf目录：存在启动配置文件和日志配置文件
