After installing docker on centos7,Failed to start docker."Job for docker.service failed."

Question

After executing yum install docker on centos7, I want to start docker by executing service docker start, then i can see the error:

Redirecting to /bin/systemctl start docker.service Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details.

then I execute systemctl status docker.service -l, then the error is:

docker.service - Docker Application Container Engine

I really have no idea, looking forward to your response, I will be very appreciative!

Solution

this error usually occurs because of missing device-mapper-event-libs package.

# yum install device-mapper-event-libs

The error no space left on device may indicate a full filesystem. Have you check how much disk space you have available to /var/lib/docker?

This Github issue suggests that yum install docker-io-selinux would fix the problem if you have selinux enabled
