| Docker 是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的Linux机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口（类似iPhone的app）。几乎没有性能开销,可以很容易地在机器和数据中心中运行。最重要的是,他们不依赖于任何语言、框架或包装系统。 |

| 如果你想安装最新版本的docker，首先，检查你的APT系统能够处理https的url：如果你的主机不存在/usr/lib/apt/methods/https文件，请先安装apt-transport-https包 |

添加Docker镜像添加你的apt软件源,更新和安装lxc-docker包。你可能会受到一个警告信息，这个包不可信，输入yes继续安装。 |

提示：这还有一个简单的curl脚本来协助你完成这一工作。 |
$curl -s https://get.docker.io/ubuntu/ | sudo sh |
注意：Ubuntu(和Debain)包含一个特别陈旧的KED3/GNOME2包叫docker,所以我们把这个包叫docker.io |
