Don't Repeat Yourself in the Cloud, Either: Deploying OpenShift Apps to a Second Instance

Learn how our document data model can map directly to how you program your app, and native database features like secondary indexes, geospatial and text search give you full access to your data. Brought to you in partnership with MongoDB.

Recently burningTyger installed Moodle on OpenShift, RedHat's relatively young PaaS. (Moodle is an extremely successful, modular, open-source learning platform. I've used it in several instances before: it can do almost anything an online educator could hope for.) This took a little bit of doing, so burningTyger posted a HowTo on github.

Soon afterward, a friend wanted to use the same app on another OpenShift domain. Well, burningTyger could have sent the friend the app, but the developer's subconscious insisted firmly: DRY, Don't Repeat Yourself! which goes for OpenShift apps too, of course. (At a very basic level, DRY seems especially apropos -- if linguistically paradoxical -- of the cloud, insofar as scalability is encoded in the concept of the cloud itself.)

So burningTyger figured out a way to deploy an OpenShift app to another instance. This means: no repeating code, just repeating setup. Simple to start, simpler to maintain. The RedHat cloud remains calm, never threatening a version-control storm.

If you're a CloudShift user, thinking of deploying an app to multiple OpenShift instances, then read burningTyger's new HowTo and see the multiple-instance problem solved before your eyes.
