Unable to run Docker from inside Docker

Docker Desktop for Windows

Expected behavior

docker command should work from within docker

Actual behavior

It gives an error

Information

Here is my session log

C:\docker\nfs_mount>docker -v
Docker version 1.11.1, build 5604cbe

C:\docker\nfs_mount>docker run --privileged=true -v /usr/bin/docker:/bin/docker -it alpine /bin/sh
/ # docker -v
Docker version 1.11.1, build 8b63c77
/ # which docker
/bin/docker
/ # docker images
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

I don’t know a solution, but this: Docker-in-docker vs mounting /var/run/docker.sock
and this: https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/ may be of interest.

I think I tried this and it worked fine, see here.

-v /var/run/docker.sock:/var/run/docker.sock

Friism, your command helped. I had to add docker binary too.

For community benefit, final command that works for me is

docker run --privileged=true -v /var/run/docker.sock:/var/run/docker.sock -v /usr/bin/docker:/bin/docker -it alpine /bin/sh

once inside docker, use
docker images

and it should show all images
