This document discusses using OpenShift and CloudBees Jenkins Platform together for DevOps. OpenShift is a PaaS built on Docker and Kubernetes that allows deploying applications and services. Jenkins can be easily started and integrated with OpenShift to use it as an elastic runtime or deployment target. Jenkins Pipeline allows defining CI/CD pipelines as code. A live demo shows using OpenShift from a Jenkins Pipeline to build and deploy an application. Additional resources are provided to learn more about the OpenShift and CloudBees integration.
