We run our builds within containers (using the Jenkins k8s plugin) for repeatability, but the generated artifacts (jars and Docker images) are pushed to our artifact repository (Artifactory) as part of the build process. Our final deployable artifact is our base image with a single layer added to include our app.jar.
