Docker 发布的方式为实现DevOps（自动化运维，需要配置 代码管理工具如Git的hook来实现提交编译、打包、发布等一系列事件控制）提供了诸多方便，辅助于Shell脚本可以很好的配合起来。
Docker镜像可以通过自动化编译，也可以通过导入镜像的方式来获得。
本文的题目叫：Shell脚本构建Docker 半自动化编译打包发布，因为我这里还没跟代码管理关联起来。
Shell脚本不同实现
导入镜像方式（镜像文件rtvsweb-publish.tar）：
构建发布方式（依靠Dockerfile来构建）：
Shell Docker构建发布脚本工具核心install.sh

整体设计实现思路
1、Docker环境准备和安装
2、MySQL环境准备和安装
3、Docker的知识：构建、运行
4、Docker镜像的版本管理
5、容期间网络访问：--link
6、镜像打包历史
7、服务运行效果
以上为个人经验，希望能给大家一个参考，也希望大家多多支持IT博客社区。如有错误或未考虑完全的地方，望不吝赐教。
