Shell实现Docker环境准备和应用服务运行

考虑问题

还是根据之前的Shell编写经验，本文需要注意几个问题：

• Docker 的容器IP获取
• 如何进入MySQL容器执行数据库脚本
• Docker应用镜像的导入导出
• Shell 脚本sed -i 修改XML参数空格问题导致参数个数解析多于预期
• 如何设计脚本执行的命令方式入口及帮助文档

示例脚本

下面是回答上面问题的一个脚本：install.sh

示例效果

执行结果：

关于脚本和应用服务的说明：

上面缺失的文件我在这里就不提供了，主要看流程设计和帮助文档。我上面实现的是ASP.NET core web的
docker应用程序的部署环境，因为涉及到Nugget包，项目发布的时候采用的部署方式是框架依赖模式，它可以将
需要的*.dll文件都生成到publish目录下。其他语言如Java的应该比这个更简单（如采用微服务框架Spring 
Boot 打成jar包即可）。
