This is a request to support the use of openshift cartridges in Cloud Engine. As users begin to develop more applications on openshift, support for cartridges in CloudForms will allow it to serve more users. Ideally, the application blueprint and cartridge format should become one and the same. An overview on openshift cartridges can be found here: https://openshift.redhat.com/community/wiki/architecture-overview More details on the cartridge format can be found here: https://openshift.redhat.com/community/wiki/introduction-to-cartridge-building/
For the sake of howto completeness: A getting start guide, incl. definitions of quickstart, DIY or a cartridge: https://openshift.redhat.com/community/wiki/learning-openshift-origin
