Add flags to docker run

Hello!

I was just playing around with docker. Could you please give me a hint how to add a flag to docker run? As far as I understood, previously this functionality was in folder cli (and functions like NewRun etc), but currently situation is much more complicated (I think that I should seek in folder api/server/, but I cannot find anything related).

Thank you!

The moby/moby repository contains the daemon, API server and API client. The docker CLI is located in the https://github.com/docker/cli repository
