About docker in docker - how to make it work without parent sock file

[aviNrich]

Hi,
I have tried your docker in docker solution from here: docker-library/docker#306 (comment)
In my docker compose file, if I wont add the following volume I will get an error:
- /var/run/docker.sock:/var/run/docker.sock
The error...
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

How can I run the Docker file without bein dependent on the host docker engine?

If its not possible, how can I connect to my dockers via localhost. mysql -u root -h localhost -p not working,

Thanks

I think maybe you should back up a hitch and describe what you're trying to accomplish?
