For those of you using deps.edn, I've added a Tool to do an opinionated jib build (https://github.com/atomisthq/jibbit). I added support for pushing the resulting image to gcr. It currently uses the gcloud cli (https://github.com/atomisthq/jibbit/blob/main/src/jibbit/gcloud.clj#L6) to fetch a token but it could be adapted to use a credentials.json if there's a need to support environments that don't have the gcloud sdk installed.
