ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

这个方法，未重启貌似无效。

https://serverfault.com/questions/767994/can-you-run-docker-natively-on-the-new-windows-10-ubuntu-bash-userspace

As of September 2016, No.

All current implementations of Docker on Windows use virtualisation, Docker 1.12 uses a hypervisor in Windows -thus removing the advantage of containerisation over virtualisation.

Docker needs more than just using Linux systems calls.

It needs process control groups (cgroups), a stackable filesystem (aufs), plus other Linux-based systems outside the kernel.

Neither cgroups nor aufs are natively in the Windows 10 kernel.

There is an implementation of Windows Server 2016 here: https://msdn.microsoft.com/en-gb/virtualization/windowscontainers/quick_start/quick_start_windows_server ..but this will only run some Windows services, e.g. IIS, and not Ubuntu

初步结论：应该WIN10内核无法完全模拟Linux的cgroup和aufs组件。
