Overview

Nexus is a repository and artifact manager used by OpenShift to cache locally build dependencies, and those used by Maven in particular, close to builds. It is recommended to set up one per OpenShift cluster, to speed up Maven builds.

Copy it locally and then:

oc process -f nexus.yaml | oc create -f -
