Docker安装
安装环境MacOS 10.12.3, 下载完docker-toolkit后点击安装，完成打开时打开 Docker Terminal时询问使用 terminal还是iterm2，选择完毕后输入命令
$ docker info
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
google了一下也没有解决方案，既然没有解决问题的钥匙，那就自己配一把。 进入/Application/Docker Terminal 下
➜ ~ ll /Applications/Docker/Docker\ Quickstart\ Terminal.app/Contents/Resources/Scripts/
iterm.scpt main.scpt start.sh* terminal.scpt
start.sh从文件名看就感觉是初始化脚本，执行后
~ /Applications/Docker/Docker\ Quickstart\ Terminal.app/Contents/Resources/Scripts/start.sh
