Hi all, I spent a bit of time putting together a high-level view of the many changes we've worked on to get our image building & platform support to where it is today https://www.technovelty.org/openstack/image-building-in-openstack-ci.html It's a bit long, but I hope it can help introduce interested people to the current environment and ongoing work in this area. Cheers, -i (p.s. thanks to the couple of #infra pre-readers for their feedback, of course more welcome :)
