Chapter 1. Introduction

OpenShift Container Platform provides an S2I (Source-to-Image) process to build and run applications where one can attach an application’s source code on top of a builder image (a technology image such as JBoss EAP). S2I process builds your application first and then layers it on top of the builder image to create an application image. After the build is complete, the application image is pushed to the Integrated registry inside OpenShift or to a standalone registry.

Red Hat Java S2I for OpenShift is a Source-to-Image (S2I) builder image designed for use with OpenShift. It allows users to build and run plain Java applications (fat-jar and flat classpath) within a containerized image on OpenShift.
