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.

Installation

Method 1

Use the following template: https://github.com/NovaOrdis/playground/blob/master/openshift/auxiliary-tools/nexus.yaml

Copy it locally and then:

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

Method 2

oc new-app sonatype/nexus3:latest

This will set "app=nexus3" label on all objects created for this application (image stream, deployment config and service).

oc expose svc nexus3
oc rollout pause dc nexus3
oc patch dc nexus3 --patch='{ "spec": { "strategy": { "type": "Recreate" }}}'
oc set resources dc nexus3 --limits=memory=2Gi --requests=memory=1Gi
echo "apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nexus-pvc
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 4Gi" | oc create -f -

oc set volume dc/nexus3 --add --overwrite --name=nexus3-volume-1 --mount-path=/nexus-data/ --type persistentVolumeClaim --claim-name=nexus-pvc

Verification

Nexus should be available at: https://nexus3-cicd.apps.openshift.novaordis.io
