Dockerfiles are really really simple. they do essentially three things: set a base image, set environment variables, and run scripts. and then as sort of a meta-thing, they prove that the steps in the dockerfile actually work, when you start the docker container and see that it works. if you don't want to run in docker, a dockerfile is still a perfect setup script. open it up and see what it does, and use that as install instructions.
