I am new to docker and cannot understand these errors. So, Please let me know if any more information is needed.

`$ docker --version`
Docker version 1.12.6, build 88a4867/1.12.6

`$ docker info`
 Cannot connect to the Docker daemon. Is the docker daemon running on this host?

`$sudo dockerd`

FATA[0000] unable to configure the Docker daemon with file /etc/docker/daemon.json: EOF

`$sudo systemctl start docker`

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

`$sudo systemctl status docker.service -l`

I have same problem. But I am edited the file /etc/docker/daemon.json and added to it some options. If string with option is not last it have to end with comma character(,).

In root user, type :

$ nano /etc/docker/daemon.json

Ff the file show blank or nothing text, then you just add :

{
}

then save and exit.

Then try to restart docker using

$ service docker restart

In my case just remove that's file using this command $sudo rm /etc/docker/daemon.json

and then restar the service $sudo systemctl restart docker.service $sudo systemctl status docker.service
