HOW TO SEND COMMANDS TO THE DOCKER DAEMON WITHOUT USING SUDO
====
If you’ve followed my previous Docker videos, you know you have to prefix each docker command by sudo--unless of course if you are directly running your shell as root. Pfff! It’s so boooring to type those five extra characters before each command…​

Joke aside, let’s think about the problem: Docker is using a client-server architecture. No doubt dockerd, the Docker server, is a privileged process that must be run as root. But what about the docker command line client? Why does it require elevated privileges? Why can’t an ordinary unprivileged user send commands to the Docker server? Well, actually (s)he can, and that only requires a tiny change of the user account configuration:

However, if we may do it, that does not necessarily mean we should do it. So, in that video, you will learn a little bit more about the Docker architecture. And most important, I will mention the potential security issues that may arise if you allow an untrusted user to interact directly with the Docker engine. That way, you will have all the keys in your hands to choose if you want to do that or not (hint: you probably do not want to do that in production).
