If you want to reduce the size more, try emitting a single layer as a tarball which you can pipe to docker load. That will reduce your layer count to one, plus you can omit a bunch of the metadata that Docker includes when you build from a Dockerfile (it doesn't seem to care at runtime).

Indeed.

Another useful technique, which has been recently introduced, is Multi-Stage Builds https://docs.docker.com/engine/userguide/eng-image/multistag... . This lets you avoid putting tools needed for compilation into the final image.
