--tlsverify Use TLS and verify the remote
--skip-hostname-check Don't check the daemon's hostname against the
name specified in the client certificate
--project-directory PATH Specify an alternate working directory

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
