针对 Windows10 下 DockerToolbox-18.03.0-ce 的安装问题
1、如果下载的是旧版本的Docker Toolbox 版本，在安装完毕后，运行终端控制台时会报错，无法正常运行并创建Docker虚拟机
由于安装的是旧的稳定版本的DockerToolBox(这里我用到的是DockerToolbox-18.03.0-ce)，运行DockerToolBox终端控制台(Docker Quickstart Terminal)时，程序提示github网站上boot2docker.iso 最新的版本是v19.03.5，程序会自动从github网站上下载v19.03.5版的boot2docker.iso文件到catch目录。因为科学上网问题，无法正常访问位于s3.amazonaws.com服务器上的文件，导致无法正常创建default虚拟机，整个创建过程及报错信息如下：
Running pre-create checks…
(default) Default Boot2Docker ISO is out-of-date, downloading the latest release…
(default) Latest release for github.com/boot2docker/boot2docker is v18.05.0-ce
(default) Downloading C:\Users\26**1.docker\machine\cache\boot2docker.iso from https://github.com/boot2docker/boot2docker/releases/download/v19.03.5/boot2docker.iso…

通过下载、拷贝最新版本的boot2
docker.iso文件（这里提供我用到的boot2docker.iso文件，2020.4.15），分别放到安装目录和缓存目录下，可以解决此问题。详细过程如下：
2、VirtualBox无法在 ‘docker-machine create’ 中启动虚拟机
由于安装的是旧的稳定版本的DockerToolBox(这里我用到的是DockerToolbox-18.03.0-ce)，一同安装的是旧版本的VirtualBox，存在旧版本中未修复的问题，整个创建过程及报错信息如下：
(default) Progress state: NS_ERROR_FAILURE
(default) VBoxManage: error: Failed to create the host-only adapter
(default) VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory
(default) VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface
(default) VBoxManage: error: Context: “RTEXITCODE handleCreate(HandlerArg *)” at line 94 of file VBoxManageHostonly.cppThis is a known VirtualBox bug. Let’s try to recover anyway… Error creating machine: Error in driver during machine creation: Error setting up host only network on machine start: The host-only adapter we just created is not visible. This is a well known VirtualBox bug. You might want to uninstall it and reinstall at least version 5.1.28 that is is supposed to fix this issue
通过下载、拷贝最新版本的VirtualBox文件（这里提供我用到的VirtualBox-6.1.6-137129-Win.exe，2020.4.15），可以解决此问题，默认安装即可。
Docker Toolbox 安装成功:)
