I am new to Docker, so don’t have much idea about it.
I tried restarting Docker service using command
service docker restart
As the command was taking too much of time I did a CTL+C
Now I am not able to start docker deamon
Any docker command gives following op
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
I tried starting Docker deamon using
systemctl start docker
But it outputs:
Job for docker.service failed because the control process exited with error code. See “systemctl status docker.service” and “journalctl -xe” for details.
Output of command
systemctl status docker.service

How would I be able to start Docker without losing any containers and using previous configurations>
