Cannot start docker on windows 10 pro?

问题:

Problem:

When I try to start docker desktop it leaves me this error.

Unable to create: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: Hyper-V was unable to find a virtual switch with name "DockerNAT".

This is the output when I issue docker version command on the terminal.

Client: Docker Engine - Community
 Version:           18.09.2
 API version:       1.39
 Go version:        go1.10.8

 Experimental:      false
error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/version: 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. 

This working without giving any error when in windows containers. But when I change it to Linux containers this happens. I tried a lot to find a solution to this problem. But I was unable to find a solution. Can someone help me to solve this problem? Thank you.

You may want to check from HyperV console to ensure there is a vnet called DockerNAT.

tray icon to see if there is some log related to why the vnet cannot be created

Here is what works for me - open Hyper-V manager and from 'Actions' panel on the right click 'Stop Service' and confirm prompt. Then, Install Docker desktop which will restart your hyper-v and create DockerNat. To check click 'Virtual Switch Manager' from 'Actions' panel and you should see it on the Left.
