If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
 
  sudo usermod -aG docker your-user
 
Remember that you will have to log out and back in for this to take effect!
 
WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.
