Docker Machine是Docker官方Orchestration项目之一，负责在多种平台上快速安装Docker环境。

Docker Machine是一个工具，它允许你在虚拟宿主机上安装Docker Engine引擎，并使用docker-machine命令管理宿主机。你可以使用机器在本地的Mac或Windows上创建和使用Docker宿主机。

Mac或Windows上运行Docke

docker-machine是一个虚拟机管理工具，通过创建一个安装好的docker虚拟机并设置对应的环境变量，使本地docker工具获得透明远程操作虚拟机的能力，从而使本身不支持docker的windows和mac能够直接使用docker命令。

远程系统上配置Docker宿主机

Docker与Docker Machine

常说的Docker实际上指的是Docker Engine引擎，它是一个客户端/服务器应用程序，由Docker守护进程、REST API指定与守护进程交互的接口、CLI命令行接口与守护进程通信（通过封装REST API），Docker Engine从CLI中接收docker命令。

Docker Engine

Docker Machine是一个用于配置和管理Docker Engine宿主机的工具，通常在本地系统上安装。Docker Machine有自己的CLI命令行客户端工具docker-machine和Docker Engine客户端工具docker。可以使用Docker Machine在一个或多个虚拟系统上安装Docker Engine。这些虚拟系统可以是本地也可以是远程的。Dockerized宿主机本身可以认为是被管理的machine。

注意事项

可以明显发现，其中一直有一个错误存在：

Windows might ask for the permission to configure a dhcp server. Sometimes, such confirmation window is minimized in the taskbar.
Error setting up host only network on machine start

VirtualBox版本

VirutalBox进程

说明虚拟机创建或者访问本地网络适配器出现了问题：windows的docker安装需要依赖虚拟机，点开虚拟机找到默认虚拟机，打开网卡，分别指定不同的网络模式然后重启你的虚拟机，这个时候使用quick startterminal还是会报错，图形界面也会报错。

重新下载 VirtualBox https://www.virtualbox.org/wiki/Downloads 的最新版本尝试下。
