windows7安装docker异常：looks like something went wrong in step ‘looking for vboxmanage.exe’

一、背景

最近准备抽点时间研究下docker，选择在家中的windows系统上安装。

我的系统是windows7，首先安装Docker Toolbox，Docker Toolbox是一个工具集，主要包含如下内容：

Docker CLI 客户端，用来运行docker引擎创建镜像和容器
Docker Machine. 可以让你在windows的命令行中运行docker引擎命令
Docker Compose. 用来运行docker-compose命令
Kitematic. 这是Docker的GUI版本
Docker QuickStart shell. 这是一个已经配置好Docker的命令行环境
Oracle VM Virtualbox. 虚拟机

安装完之后，桌面得到如下内容：

此时，通过双击Docker Quickstart Termimal启动。

二、问题

1、问题：looks like something went wrong in step ‘looking for vboxmanage.exe’

一切进行顺利，直到。。。在终端出现如下异常：looks like something went wrong in step ‘looking for vboxmanage.exe’

常规心态：一般出现这种找不到文件的异常都是因为安装目录有问题导致，所以首先看下Docker Quickstart Termimal是从哪里创建的快捷方式，右键->属性

紧跟路径，打开脚本文件start.sh，发现了异常提示是出现在地20行，如下所示：

 直观感觉就是由于变量“${VBOX_MSI_INSTALL_PATH}”，或者变量“${VBOX_INSTALL_PATH}”获取异常导致，首先查看环境变量，是否该变量没有写入

发现一切正常，那就通过打印这个变量的值来验证下这个想法，使用最暴力直接的方法，输出变量“${VBOX_MSI_INSTALL_PATH}”，为了防止脚本继续执行，通过read断点

再次运行Docker Quickstart Termimal，结果如下：

发现变量正常解析，那么问题可能不在这里，继续向下断点排查，直到这里

问题直接指向变量"${DOCKER_MACHINE}"获取异常，而该变量是在脚本第18行定义：DOCKER_MACHINE="${DOCKER_TOOLBOX_INSTALL_PATH}\docker-machine.exe"，使用相同的方法，输出变量${DOCKER_TOOLBOX_INSTALL_PATH}

很明显，该变量获取为空，我的docker-machine.exe是安装在“D:\usr\Docker Toolbox\”，所以直接修改脚本：

同样，将脚本中该变量全部替换为具体路径，再次运行Docker Quickstart Termimal，问题解决，其他一切顺利！

三、其他

附上我个人使用的脚本代码，替换掉响应路径即可
