2017 春节为了准备17年的项目安排开始尝试恢复Hippo Docker，但是原先的Ubuntu因为空间的问题所以准备重新折腾
先装了Ubuntu14.04，因为这个是我下载的版本，后来在装Hippo Docker的时候才发现原来新的版本的Ubuntu已经是16.04了，折腾了几天升级台式机和笔记本电脑中的虚拟机环境里面的Ubuntu.
升级Ubuntu用的命令是 sudo update-manager -d；sudo do-release-update
后来的CentOS的安装过程颇为坎坷，装好后怎么也没发联网。后来干脆装了个只有命令行的版本。
然后用了同一个Dockerfile成功build成了Hippo的Docker IMG.
sudo docker build -t=”hippo/demo” .
Dockerfile:
