Here is the BuildConfig to generate the quarkus app-image for deployment (via DC)

notice the use of some env vars to customize the Maven build

impor the ubi8-openjdk-8 image stream into your namespace

oc import-image --confirm ubi8/openjdk-8 --from=registry.access.redhat.com/ubi8/openjdk-8 -n {{ project_name }}
