[docker][win10]安装的坑

1. 右键这个小图标，先signin，注意这里是ID 不是邮箱

2. 可能starting 时候就报错说
   “Containers feature is not enabled”
   或者

总结一下，
首先确认Hyper-V启动

第二应该确保：

如果你的显示禁用， Enabled Virtualization (Hyper-V, etc) in your BIOS， 你得开机进入BIOS里把Virtualization的选项变成Enabled（不同机子的Virtualization可能在不同的选项下，去看一下advanced之类的）

3. 在bash 里打docker ps
   就开始报错

   error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/containers/json: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

解决办法：
https://github.com/docker/for-win/issues/1825

cd "C:\Program Files\Docker\Docker"
./DockerCli.exe -SwitchDaemon

再试试, 就正常了
docker ps

docker run hello-world
