OpenShift Origin in AWS

This describes deploying and running OpenShift Origin in Amazon Web Services.

This is based upon the code and installer on 2014-02-26 so YMMV.

We will be using a VPC for deployment in us-east-1 and Route53 for DNS. I will leave the VPC setup as an exercise for the reader.

Prerequisites

• AWS Account
• VPC
