Due to a bug in OpenShift you need to create an SSH tunnel from your local machine to the OpenShift instance in order to access the web console, see: openshift/origin#19699 (comment)

@mauricios you can replace line 11, with this:
sudo sed -ie 's/OPTIONS="--default-ulimit nofile=1024:4096"/OPTIONS="--default-ulimit nofile=1024:4096 --insecure-registry 172.30.0.0\/16"/g' /etc/sysconfig/docker
Please note the back slash for the segment 172.30.0.0/16, and i get rid of the back slashes in the white spaces for the input search string.
