mac 上安装与卸载docker

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

    添加到 .bash_profile 或者 .zshrc， 之后关闭iterm或者source xxx

    ok，安装完毕
    $ docker pull ubuntu 试试
    
     由于pull官方的register hub可能速度比较慢：
     推荐docker.io加速器：
     
     
     安装完docker之后，也可以安装个docker-compose工具：
     brew install docker-compose

    参考官方文档：
2.卸载docker：
     参考：
     卸载脚本uninstall.sh：
     

#!/bin/bash

# Uninstall Script

if [ "$(which boot2docker)" == "" ]; then
    echo "boot2docker does not exist on your machine!"
    exit 1
fi

if [ "${USER}" != "root" ]; then
    echo "$0 must be run as root!"
    exit 2
fi

echo "Stopping boot2docker processes..."
boot2docker stop && boot2docker delete

echo "Removing boot2docker executable..."
rm -f /usr/local/bin/boot2docker

echo "Removing boot2docker ISO and socket files..."
rm -rf ~/.boot2docker
rm -rf /usr/local/share/boot2docker

echo "Removing boot2docker SSH keys..."
rm -f ~/.ssh/id_boot2docker*
