1.安装Docker：
    1.1 brew update
    1.2 brew install boot2docker
    1.3 boot2docker upgrade
    1.4 boot2docker init
    1.5 boot2docker up
    1.6设置ENV:

    export DOCKER_HOST=tcp://192.168.59.103:2376

    export DOCKER_CERT_PATH=/Users/wangxigang/.boot2docker/certs/boot2docker-vm

    export DOCKER_TLS_VERIFY=1

    Add to .bash_profile or .zshrc, then close iterm or source xxx

    ok, after installation
    $ docker pull ubuntu try it
    
     because the official register hub may be slow to pull:
     recommended docker.io accelerator:
      https://dashboard.daocloud.io /mirror
     
     After installing docker, you can also install a docker-compose tool:
     brew install docker-compose

    Refer to the official documentation: https://docs.docker.com/installation/mac/
