碰到的错误就是那permission denied '/root/.config/configstore/insight-yo.yml'呀，Native thread-sleep not available呀NuGet cache之类的错误。前者是yeomon的，后者是nodejs安装的不够新（apt-get install nodejs的是0.10级别的版本，谁想的到啊）
做好的docker image叫 。
docker run -it osexp2000/dnetcore-docker-image
进去之后就是bash，以devuser用户运行在/home/devuser，这个用户能够sudo（无需密码）。
进去就可以顺利的运行aspnet模版生成工具yeomen了。
yo aspnet
里面什么npm和yeomen之类的东西都准备好了，甚至基本的vim,lsof，netstat之类的都准备好了，不然真不方便查看环境。
运行的样子是这样的：
$ docker run -it osexp2000/dnetcore-docker-imagedevuser@640be8c28a81:~$ iduid=1000(devuser) gid=1000(devuser) groups=1000(devuser),27(sudo)devuser@640be8c28a81:~$ yo aspnet? ==========================================================================We're constantly looking for ways to make yo better!

Dockerfile放在了。很少，干脆贴下来。

可以自己存起来build成docker image
docker build -t IMAGE_NAME_HERE --rm - < Dockerfile
下次再沿着继续学。不过我想看看如何通过Mac OS X里的Visual Studio Code来直接把代码发布到docker里。
