2. OpenShift Origin is an Open Source project
3. Introduction • OpenShift Origin is a distribution of Kubernetes optimized for continuous application development and multi-tenant deployment. OpenShift adds developer and operations-centric tools on top of Kubernetes to enable rapid application development, easy deployment and scaling, and long-term lifecycle maintenance for small and large teams. • Project spaces • Build tools • Integration with your IDE
4. We need more than just Orchestration !
5. Architecture
7. Kubernetes Embedded https://master:8443/api = Kubernetes API /oapi = OpenShift API /console = OpenShift Web-Console OpenShift Kubernetes 1 Binary for Master ApiServer, Controller, Scheduler, Etcd 1 Binary for Node KubeProxy, Kubelet 1 Binary for Client Kubelet
8. Things OpenShift adds to Kubernetes • Source code management, builds, deployments. • Managing and promoting images using Source to Image (S2I) and Internal Docker Registry. • OpenShift is more of developer facing and Kubernetes is more of operations teams. • Dedicated web console • Team and User tracking for organizing a large developer organization. • App management at scale.
9. Contributions from RHT/OpenShift to Kubernetes
10. Benefits of OpenShift over orchestration providers • Generally you start with containerizing your application i.e. build your own containers. • But with OpenShift you don’t have to worry about it, OpenShift will build containers for you. • But if you want to run your own containers you can do that as well.
