Nice! Thanks this is useful. Just two things:

1. Can you add a mention to this in the README?
2. Ruby needs to be installed so that the parser for Chef works

Just updated, feel free to suggest changes. I splitted the instruction in README in two parts INSTALL and USAGE, do you prefer in a different way?

Ah, one more thing, I pushed the image for my dockerhub account: https://hub.docker.com/repository/docker/ruimartinsptl/sr-lab-glitch/general

If you create an sr-lab account in dockerhub, we can create an official imagem there :) (because for now people need to execute the docker build locally, or use my image ruimartinsptl/sr-lab-glitch, but is not official)

Yes that is a good idea! We'll work on that soon, I'm not sure if there is a sr-lab account yet. However I think it is also not a big deal right now to build the image locally as the image is really small and consequently really fast to build.

LGTM! Thank you, I'll merge the PR
