Win10 Docker安装之坑

安装win版的docker前一定要搞清楚：Docker for windows 和 Docker Toolbox的区别。

Docker for Windows是依赖Hyper-V。

Docker ToolBox在安装时会安装VirtualBox，是依赖VirtualBox的。

如果你在安装了Hyper-V的windows10上，再安装Docker ToolBox，将可能非常惨烈。

问题一、如果已经在windows中开启了Hyper-V，启动Docker QuickStart Terminal的时候就会出现。

Running pre-create checks...
Errorwithpre-create check:"This computer is running Hyper-V. VirtualBox won't boot a 64bits VM when Hyper-V is activated. Either use Hyper-V as a driver, or disable the Hyper-V hypervisor. (To skip this check, use --virtualbox-no-vtx-check)"
Looks like something went wronginstep ´Checkingifmachinedefaultexists´...Press any key tocontinue...

解决方案1：
在添加windows功能里面吧Hyper-V功能关闭，重启电脑
解决方案2：
修改启动文件允许创建默认的VM，要修改的文件位于C:\Program Files\Docker Toolbox\start.sh`,必须以管理员身份才能修改文件。
在脚本中找到以下代码：

STEP="Checking if machine $VM exists"
if [ $VM_EXISTS_CODE -eq 1 ]; then
  "${DOCKER_MACHINE}" rm -f "${VM}" &> /dev/null || :
  rm -rf ~/.docker/machine/machines/"${VM}"
  #set proxy variables if they exists
  if [ "${HTTP_PROXY}" ]; then
    PROXY_ENV="$PROXY_ENV --engine-env HTTP_PROXY=$HTTP_PROXY"
  fi
  if [ "${HTTPS_PROXY}" ]; then
    PROXY_ENV="$PROXY_ENV --engine-env HTTPS_PROXY=$HTTPS_PROXY"
  fi
  if [ "${NO_PROXY}" ]; then
    PROXY_ENV="$PROXY_ENV --engine-env NO_PROXY=$NO_PROXY"
  fi
  "${DOCKER_MACHINE}" create -d virtualbox $PROXY_ENV "${VM}"
fi

倒数第二行是创建虚拟机的地方：
"${DOCKER_MACHINE}" create -d virtualbox $PROXY_ENV "${VM}"
修改改行，加入--virtualbox-no-vtx-check，最终结果是：
"${DOCKER_MACHINE}" create -d virtualbox --virtualbox-no-vtx-check $PROXY_ENV "${VM}"
保存更改，再次运行 Docker QuickStart Terminal

问题二、如果按照上面解决方案二解决，运行Docker QuickStart Terminal依然报错，错误为下面代码。

VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
 

那么，你就必须要关掉Hyper-V了，然后重启电脑。

问题三、如果之前安装，存在创建虚拟机(VM)失败的情况。此时应该在VirtulBox中删除创建过程中出错的虚拟机，重新创建虚拟机。
