本次拟打算用比较新的tutor版本来构建镜像，当前最新的tag是v3.12.2。在使用前下载安装好docker-compose，这个docker-compose一定要直接下载二进制文件安装，ubuntu16.04自带的docker-compose版本太老，达不到tutor的要求，安装tutor使用命令如下：
git clone https://github.com/overhangio/tutor.git –branch v3.12.2 –depth 1
cd tutor
git checkout -b myrelease
cd ..
virtualenv tutorenv -p /usr/bin/python3.6
cd source tutorenv/bin/activate
cd tutor
pip install -e .
一、构建OpenEdx的镜像（含LMS、CMS）
使用容器构建命令，执行构建前要先生成运行时的一些配置文件：
tutor config save –interactive #或者执行tutor local quickstart并中断任务来生产配置文件
tutor images build openedx #第一次执行该命令会提示输入域名信息
生产的配置文件内容如下，修改些配置：
cat ~/.local/share/tutor/env/build/openedx/Dockerfile
FROM docker.io/ubuntu:16.04
