The basics to build this project and test it locally
Jenkins images can be built using podman, buildah or docker. For historical reasons, the default build runtime is docker
To build on podman:
make VERSIONS="2 maven-3.5" BUILD_COMMAND="podman build --no-cache"
To deploy your Jenkins built images refer to the section [ Deploying on an OpenShift Cluster ]
Be sure that you are logged-in with an OpenShift cluster or that KUBECONFIG environment variable points to a valid kubeconfig.
