OpenShift Origin would be a great place to showcase the WildFly application runtime. In particular, Origin includes a Java cartridge that could use WildFly as its runtime dependency. However, because WildFly is not distributed in RPM form, it cannot be included in the dependency chain.
There have been several discussions on the lack of a Java runtime on the OpenShift mailing lists, most recently:
And a bug has been opened against the OpenShift project as well:
However, these issues must be resolved upstream and it is our hope that the WildFly community will take this opportunity to become the de facto standard Java application runtime for OpenShift Origin.
