In the last days, I create an OpenShift quickstart for SuiteCRM. You can find the this openshift quickstart on GitHub.

After the command above executed with success you can access the following URL: http://suitecrm-$yournamespace.rhcloud.com and I few seconds you will have your SuiteCRM created. The default credentials are username "admin", password "admin". And as you can see in few minutes you have your CRM installed running on OpenShift Cloud.
