Here is a related bug [1] and implementation [1] for that. PTAL folks!

[1] https://review.openstack.org/#/q/topic:base-container-reduction

> Let's also think of removing puppet-tripleo from the base container.
> It really brings the world-in (and yum updates in CI!) each job and each 
> container!
> So if we did so, we should then either install puppet-tripleo and co on 
> the host and bind-mount it for the docker-puppet deployment task steps 
> (bad idea IMO), OR use the magical --volumes-from <a-side-car-container> 
> option to mount volumes from some "puppet-config" sidecar container 
> inside each of the containers being launched by docker-puppet tooling.
