Hello,

There are a few reasons we have been talking about with Tyler

* The Nodepool image imported to Docker ends up being 4.2GBytes on 
Docker which is rather large. That is merely to accomodate all potential 
use case since a single image is used for every kind of jobs.

* We got operations/puppet migrated to Docker as a proof of concept and 
are polishing the details. Notably as how to cache package managers and 
git repositories.

* We would most probably dish out puppet to provision the image since it 
offers little value. The replacement would be plain shell commands and 
we gotta translate everything.

So the main challenge is to have several Docker containers and have them 
regenerated and published automatically to a registry.


There is also the challenge of having to maintain code for three 
different distributions (trusty, jessie, stretch).

Once Trusty is phased out, we would add stretch images and that will 
probably be under Docker.
