一、背景
最近准備抽點時間研究下docker，選擇在家中的windows系統上安裝。
我的系統是windows7，首先安裝Docker Toolbox，Docker Toolbox是一個工具集，主要包含如下內容：
Docker CLI 客戶端，用來運行docker引擎創建鏡像和容器 Docker Machine. 可以讓你在windows的命令行中運行docker引擎命令 Docker Compose. 用來運行docker-compose命令 Kitematic. 這是Docker的GUI版本 Docker QuickStart shell. 這是一個已經配置好Docker的命令行環境 Oracle VM Virtualbox. 虛擬機
安裝完之后，桌面得到如下內容：
此時，通過雙擊Docker Quickstart Termimal啟動。
二、問題
1、問題：looks like something went wrong in step ‘looking for vboxmanage.exe’
一切進行順利，直到。。。在終端出現如下異常：looks like something went wrong in step ‘looking for vboxmanage.exe’
常規心態：一般出現這種找不到文件的異常都是因為安裝目錄有問題導致，所以首先看下Docker Quickstart Termimal是從哪里創建的快捷方式，右鍵->屬性
緊跟路徑，打開腳本文件start.sh，發現了異常提示是出現在地20行，如下所示：
直觀感覺就是由於變量“${VBOX_MSI_INSTALL_PATH}”，或者變量“${VBOX_INSTALL_PATH}”獲取異常導致，首先查看環境變量，是否該變量沒有寫入
發現一切正常，那就通過打印這個變量的值來驗證下這個想法，使用最暴力直接的方法，輸出變量“${VBOX_MSI_INSTALL_PATH}”，為了防止腳本繼續執行，通過read斷點
再次運行Docker Quickstart Termimal，結果如下：
發現變量正常解析，那么問題可能不在這里，繼續向下斷點排查，直到這里
問題直接指向變量"${DOCKER_MACHINE}"獲取異常，而該變量是在腳本第18行定義：DOCKER_MACHINE="${DOCKER_TOOLBOX_INSTALL_PATH}\docker-machine.exe"，使用相同的方法，輸出變量${DOCKER_TOOLBOX_INSTALL_PATH}
很明顯，該變量獲取為空，我的docker-machine.exe是安裝在“D:\usr\Docker Toolbox\”，所以直接修改腳本：
同樣，將腳本中該變量全部替換為具體路徑，再次運行Docker Quickstart Termimal，問題解決，其他一切順利！
三、其他
附上我個人使用的腳本代碼，替換掉響應路徑即可
