launch docker without sudo

First, we must create the docker group:

sudo groupadd docker

Then, add your current user to the docker group:

sudo gpasswd -a ${USER} docker

Now you can restart the Docker daemon:

sudo service docker restart

Now you should be able to run it without sudo:

docker run hello-world

If you have any problem, try logging out/in or rebooting your machine.
