We are evaluating Openshift Origin on an existing OpenStack on-premise cloud. So far I have been playing around with the oc cluster up deployment on a local workstation and it works fine but I haven't played around with the CI/CD option (they support jenkins deployments, etc).
From the docs I see that there is a bit of complexity regarding the security constraints and integration of volumes that I need to wrap my head around.
I also attended the DevConf.cz and saw a lot of presentations regarding Openshift. They have most of the talks on youtube (https://www.youtube.com/channel/UCmYAQDZIQGm_kPvemBc_qwg) in case somebody is interested
