安装之前先了解下关键概念：
在linux上安装Docker，你的机器即使localhost也是docker主机；在网络中，localhost是指您的计算机。docker主机是容器中在该机器上运行。说白了就是直接安装在linux上，英文翻译真蛋疼。
在Windows安装，Docker守护进程运行Linux虚拟机内。您可以使用Windows的客户端与虚拟机中的Docker主机通信。这台主机中运行你的Docker容器。
在Windows中，Docker主机地址是Linux VM的地址。当启动docker-machine虚拟机时会被分配一个IP地址。当你启动一个容器，容器的端口会映射到VM。
安装

或者去github上下在：https://github.com/boot2docker/windows-installer/releases
不能下载 可以到网盘下载 链接: http://pan.baidu.com/s/1jGrkJ7w 密码: 3xie
基本是下一步，下一步，最后一步选上 加到path：
the Docker Quickstart Terminal
装完后桌面上会多出几个图标，其中有一个是Docker Quickstart Terminal，双击运行，居然出现错误：
关掉，已管理员身份运行：

瞅一眼Docker主机是什么样子的：
通过运行hello-world容器来验证是否安装成功：
lei@ganlei MINGW64 ~
$ docker run hello-world

Status: Downloaded newer image for hello-world:latestHello from Docker.
This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the “hello-world” image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker Hub account:
