On Ubuntu 16.04 LTS whenever trying using docker login command the following warring message will be show : 

docker login

Once I have tried that solution .initially it didnt work, but it worked after RESTART of whole system.

you have to add the user to the docker group as the other posts suggest 

usermod -aG docker $USER

This change won't affect your current terminal session however. If you don't want to login/logout you can use 

newgrp - docker

for the change to affect to your current terminal session.

To use docker in the user mode use the following command: sudo chmod 666 /var/run/docker.sock
