This git repository helps you get up and running quickly w/ an XWiki (http://www.xwiki.org/) installation on JBoss EAP 6.X with PostgreSQL using OpenShift
Create an account at http://openshift.redhat.com/ , don't forget to create a namespace and install Git, Ruby and the client tools.
Install the client tools on your machine if you have not already done so.
sudo gem install rhc
Create the application.
rhc app create -a xwiki jbosseap-6 postgresql-9.2 -g large --from-code git://github.com/rkmallik/xwiki-example-postgresql
XWiki requires a little more than just the 1GB of disk storage. Unfortunately, the rhc app create command does not yet allow for you to create an app with additional storage out of the gate, so we have to do that manually. Vote for that feature here: https://www.openshift.com/content/create-a-gear-with-extra-storage
Add an extra gigabyte of storage:
rhc cartridge storage jbosseap-6 -a xwiki --add 1gb
Then, restart the app:
rhc app restart xwiki
And that's it, you can now checkout your XWiki install at:
