Docker Client is not connecting to its docker daemon on window subsystem

I am using WSL (Window Subsystem for Linux) 2 to install ubuntu and it works fine for me. Next tesk I want to install docker-ce on ubuntu subsystem so that I can do some docker testing. For that I am following this link. Followed exactly same step mentioned in article. But still my docker client is not connecting to its daemon.

Please see the below image for more information.

Infact, when I am trying to see the status of docker service using following command then its says "Docker is not running". I explicitly tried to run it but same status.

sudo service docker status

can someone help me on this, what I am missing here. why my docker client is not able to connect its docker daemon?

So, finally I was able to find the answer for this problem. I was not running ubuntu subsystem as administrator. Because of that docker daemon was not running. When I was trying to run it explicitly using sudo service docker service it was failing but was not showing any error on console. Then I used sudo dockerd command for this and it started complaining about cgroup memory issue. After that I ran it using administrator mode and it worked fine.
