Architecture
The main difference between OpenShift and vanilla Kubernetes is the concept of build-related artifacts. In OpenShift, such artifacts are considered first class Kubernetes resources upon which standard Kubernetes operations can apply. OpenShift's client program, "oc", offers a superset of the standard capabilities bundled in the mainline "kubectl" client program of Kubernetes. Using this client, one can directly interact with the build-related resources using sub-commands (such …
