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
