I hope I'm not carried away by the example, but I would definitely not build Docker images using make. A multi-stage Dockerfile can take care of building, testing, packing, etc. source code a lot more predictably than any amount of make, by using known images of the tools involved (e.g., node, webpack, etc.). Moreover, Docker's caching implicitly allows to declare dependencies with a lot fewer headaches than make. On the downside, it is all to easy to write something that busts Docker's cache early in the build process, rendering `docker build` super-expensive. So my opinionated tooling: docker, git (to extract project versions and inject them into the image), bash (to glue everything together). Everything else belongs inside the Docker build.
