I am looking at the examples. They all have a Docker file. If that just for local development on my laptop?

Using the deploy command line tool is the Docker file used to determine dependencies for the hosted VM? What if a developer is using an unusual programming language, like Common Lisp. Is that doable?

A Dockerfile is just a file with a bunch of commands to execute and get a working "computer". https://github.com/combust-labs/firebuild is fairly aged translation of the Dockerfile to a VM rootfs.
