一.实验镜像准备
1>.自行安装harbor服务及制作web服务镜像
配置Harbor支持https功能实战篇: https://www.cnblogs.com/yinzhengjie/p/12237263.html 自定义haproxy镜像: https://www.cnblogs.com/yinzhengjie/p/12231702.html 自定义tomcat业务镜像: https://www.cnblogs.com/yinzhengjie/p/12230043.html 基于DockerFile制作yum版nginx镜像: https://www.cnblogs.com/yinzhengjie/p/12194460.html
2>.在harbor服务端新建镜像仓库
3>.将haproxy镜像推送到harbor服务器端

三.使用docker-compose工具
1>.操作平台及试验架构说明
使用docker-compose工具自动生成三个容器应用，即harpoxy,nginx-web,tomcat-app01。
harpory应用功能:
负载均衡服务器，主要将访问80端口的转发给后台的nginx-web应用，暴漏8888端口为harpoxy的状态页。
nginx-web应用功能：
主要讲访问"/app01"的path调度到后端的tomcat-app01应用服务上。
tomcat-app01:
主要提供tomcat应用的访问页面。
以上三种镜像我在之前的笔记也分享过，制作起来也非常简单，可参考我第一部分提供的连接自行制作即可。
2>.为了实验方便,建议找一台干净的宿主机(只需要安装docker环境即可) ，或者将该节点的所有容器和镜像都删除掉

7>.验证服务是否生效
8>.访问haproxy的状态页
浏览器访问"http://docker102.yinzhengjie.org.cn:8888/haproxy-status"会弹出如上图所示的对话框。 输入咱们自定义的用户名和密码登录成功后，就可以看到haproxy状态页面,如下图所示。
