“An OpenShift Enterprise administrator can deploy routers to nodes in an OpenShift Enterprise cluster, which enable routes created by developers to be used by external clients.” “An OpenShift Enterprise route exposes a service at a host name, like so that external clients can reach it by name.” The first block that I didn’t recognize in the diagram is the orange “Routes” block. OpenShift project (Namespace) Routes/Routers below shows Kubernetes components in purple and OpenShift components in orange.įigure 1. Kubernetes is an open source, container as a service (CaaS) project originating from Google.įigure 1. OpenShift is a platform as a service (PaaS) from Red Hat that is built on Docker and Kubernetes. I’ll cover some of the infrastructure differences between Kubernetes and OpenShift - specifically, the differences between route/router and ingress/ingress controllers and between namespaces and projects. I wrote this to assist people who are familiar with Kubernetes but unfamiliar with Openshift, so that they can understand the different verbiage used in each ecosystem. Red Hat Openshift is a Platform as a Service based on Kubernetes, but I was largely unaware of the different terms in use in the OpenShift ecosystem. We are partners with Red Hat, so I was asked to skill up on Red Hat Openshift. I’m a Cloud Consultant at Levvel that specializes in Kubernetes. The Differences Between Kubernetes and Openshift
