Run Docker commands without sudo
- Add the docker group if it doesn't already exist
$ sudo groupadd docker
- Add the connected user $USER to the docker group
Optionally change the username to match your preferred user.
$ sudo gpasswd -a $USER docker
IMPORTANT: Log out and log back in so that your group membership is re-evaluated. 3. Restart the docker daemon
$ sudo service docker restart
If you are on Ubuntu 14.04-15.10, use docker.io instead:
$ sudo service docker.io restart
