Using Docker Without Sudo

i have this error:

FATA[0000] Get http:///var/run/docker.sock/v1.17/info: dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?

it’s occur because my user is not in docker group, to fix:

$ sudo usermod -a -G docker $USERNAME

$ newgrp docker

the last command login in the docker group in current shell
