關於Docker Toolbox安裝的docker更換儲存位置，全網都沒有多少資料，過程中參考了下面這篇博文，感謝

Docker Toolbox替換預設docker machine的儲存位置
https://www.cnblogs.com/ginponson/p/8601320.html

先說一下我的情況，系統是windows server 2012 R2，C盤不夠用，所以需要更換預設儲存位置，我安裝的toolbox版本是19.03.1
操作步驟：

1. 在開始安裝之前就配置環境變數（如果已經安裝了，需要解除安裝，按照上面那篇博文操作，我沒有成功）
   以我的為例：
   新增變數名：MACHINE_STORAGE_PATH
   
   值為F:\Docker\machines
   

建議：
這裡可以先去github下載一下boot2docker.iso，這個需要下載最新版本
下載好後新建個cache目錄，路徑為：F:\Docker\cache，然後把boot2docker.iso放進去

2. 然後再執行DockerToolbox-19.03.1.exe進行安裝
   這裡直接next就行，都是選擇預設配置，無需額外操作

3. 安裝完後，進入目錄F:\Docker\machines\machines\default，編輯config.json，配置國內映象（從這裡也可以看出，儲存位置在F盤，如果切換不成功，配置項的路徑都是在C盤）

}

4. 然後就可以正常執行Docker Quickstart Terminal了
