When installing OpenShift and Docker using

[root@localhost ~]# yum install origin-clients
...

We received the following error when trying to start the oc cluster

[root@localhost ~]# oc cluster up

   Error: did not detect an --insecure-registry argument on the Docker daemon
   Solution:

     Ensure that the Docker daemon is running with the following argument:
        --insecure-registry 172.30.0.0/16

To resolve this we needed to update the following file /etc/sysconfig/docker

# Modify these options if you want to change the way the docker daemon runs
OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false --insecure-registry 172.30.0.0/16'

Now stop and start docker

[root@localhost ~]# systemctl stop docker
[root@localhost ~]# systemctl start docker

And try to restart the oc cluster

[root@localhost ~]# oc cluster up
Starting OpenShift using openshift/origin:v3.6.1 ...
OpenShift server started.
