Can I run Docker-in-Docker without using the --privileged flag

I'd like to use Docker-in-Docker however the --privileged gives blanket access to devices. Is there a way to run this using a combination of volumes and cap-add etc. instead?

Unfortunately no, you must use the --privileged flag to run Docker in Docker, you can take a look at the official announcement where they state this is one of the many purposes of the --privileged flag.

Basically, you need more access to the host system devices to run docker than you get when running without --privileged.
