docker fails to start

I am running docker on CentOS 7. (docker from centos repo. not that of docker-engine). docker was running perfectly but for some reasons i tried to reinstall it. Unfortunately docker.service refused to start and shows me the next couple of errors:

Jan 24 15:19:28 fms-provisioner-4.novalocal systemd[1]: Job docker.service/start failed with result 'dependency'.

Jan 24 15:21:30 fms-provisioner-4.novalocal systemd[1]: Dependency failed for Docker Application Container Engine.

-- Subject: Unit docker.service has failed
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel 
-- Unit docker.service has failed.
-- The result is dependency.

Jan 24 15:21:30 fms-provisioner-4.novalocal systemd[1]: Job docker.service/start failed with result 'dependency'.

Jan 24 15:28:49 fms_k8s_minion2 systemd[1]: [/usr/lib/systemd/system/docker.service:17] Unknown lvalue '--add-runtime docker-runc' in section 'Service' 

Jan 24 15:43:09 fms_k8s_minion2 systemd[1]: Dependency failed for Docker Application Container Engine.
-- Subject: Unit docker.service has failed
-- Defined-By: systemd

Please may someone tell me what's going on ?

Thanks all for your answers but i forgot to mention that i am using flannel with docker. it such case, flannel was down do docker won't to start. that's mainly what was causing my issue. sorry for disturbing.

Looks like your Docker build is configured to use `runc:

 [/usr/lib/systemd/system/docker.service:17] Unknown lvalue '--add-runtime docker-runc' in section 'Service'

You could install runc, but that probably won't fix the issue:

sudo yum install runc

runC is lightweight, portable implementation of the the Open Container Format (OCF), you can find more about it in documentation.

Anyway the --add-runtime flag was added in Docker 1.12, unless there's at least docker-engine 1.12.0 in your repository remove the flag in /usr/lib/systemd/system/docker.service and reload the service:

sudo systemctl daemon-reload
sudo systemctl restart docker

Try to restart docker daemon and service by using sudo systemctl daemon-reload and sudo systemctl restart docker if this do not help than Remove docker and try curl -sSL http://get.docker.com | sh sudo systemctl restart docker
