Scenario

A docker/Dockerfile for a leiningen-based clojure project. Pushes are detected by Google Cloud Build ("./cloudbuild.yaml"), which builds the Dockerfile and pushes it to gcr.io/personalsdm-216109/linking-test-gcr. This image is based on the java-atomist base image that we use internally.

• run ./bump.clj (executable - requires bb installation) to increment a version to increment a version and push.
• Google Cloud Build is setup to see this push and to build and push docker/Dockerfile (a multi-stage Dockerfile using lein metajar)
• resulting Image tagged with latest and pushed to gcr.io/$PROJECT_ID/linking-test-gcr.
• A subscription on the gcr topic is set up to notify Atomist when images are pushed to this registry.
• labels org.opencontainers.image.revision and org.opencontainers.image.source have been added to the builds (in "./cloudbuild.yaml")
