Question
OpenShift Origin (Scalable Apps) on DigitalOcean
- Posted July 28, 2014
This blog posting describes installation of OpenShift Origin (OO) on a DigitalOcean (DO) droplet: http://mfojtik.im/openshift-on-digitalocean
Having minimal experience with OO, and no experience with DO, I’m unclear about how scalable apps would be supported with OO on DO.
Would I, for example, purchase droplets as required and install OO on each droplet, and then be able to configure the OO broker so that the OO PaaS’ load balancing and failover works correctly?

OO uses kubernetes.io, and is built on top of it…they were a heavy contributor to it. kubernetes then sets up docker containers and OO basically manages those for you with ease. at least that is my understanding of it…see advanced installation of OO. To read how to dynamically scale between 2 servers…once you get this, then you can understand how it might scale between 2 droplets. Then see how to add additional nodes to your OO setup.
@willfarnaby the best way to connect with other people deploying OpenShift Origin is thru the freenode irc channel #openshift-dev
You can also go to http://install.openshift.com and find more information there on deploying OpenShift Origin or Enterprise in a number of different configurations (redundant brokers/multiple nodes, HA, etc). I’ve done a couple of test deployments on Digital Ocean myself with multiple nodes without any trouble. The scripts worked reasonably well; there was nothing specific to DO that stood out.
I see now that the video link referenced in the blog posting discusses installation.
Still, it’d be of interest to hear from anyone that has installed and used multiple OpenShift Origin nodes on DigitalOcean.
