docker一键部署启动java web项目

部署企业应用经常会遇到一些问题，根据以往的经验大概罗列一下：

• 离线环境。不能访问公网，不能下载各种包，特别是在linux中不能用yum来安装所需要的环境。
• 实施人员对部署环境不能掌控。部署软件特别多的情况下，经常由于实施人员细节的小错误造成启动失败，以至于一直打电话排查原因。
• 软件多而繁杂。复杂的项目里面会用到各种组件，如tomcat、nginx、mysql、redis、mongodb、消息组件（rabbitmq、activemq等），组件多也会导致各种各样调试出现的问题。

以上问题可以用docker配合一定shell脚本就能全部搞定，实施人员到现场配置好网络等基本机器配置，就能在几分钟一键部署并启动java web项目。

下面的代码是一个例子，可以参考下，具体的代码在github上
