[openstack-dev] [tripleo] A sneak peek to TripleO + Containers

I've been playing with a self-installing container for the containerized TripleO
undercloud and I thought I'd share some of the progress we've made so far.

This is definitely not at its final, ideal, state but I wanted to provide a
sneak peek to what is coming and what the updates/content of the
TripleO+Containers sessions will be next week at the PTG.

The image[0] shows the output of[1] after running the containerized composable
undercloud deployment using a self-installing container[2]. Again, this is not
stable and it still needs work. You can see in the screenshot that one of the
neutron's agent failed and from the repo[3] that I'm using the scripts we've
been using for development instead of using oooq or something like that. One
interesting thing is that running[2] will leave you with an almost entirely
clean host. It still writes some stuff in `/var/lib` and `/etc/puppet` but that
can be improved for sure.

Anyway, after all the disclaimers, I hope you'll be able to appreciate the
progress we've made. Dan Prince has been able to deploy an overcloud on top of
the containerized undercloud already, which is great news.
