You have to be root to set it up, but after that you don't need any special privileges. With Docker the only option is to basically give everyone root access.

It's true that it requires root for some setup though. Unclear if op was complaining about that.

Yeah, I mean what do you expect or is the alternative? If you have a process that needs access to something only root typically can do, and the solution been to give that process root so it can do it's job, you usually need root to be able to give that process permission to do that thing without becoming root. Doesn't that make sense? What alternative are you suggesting?
