I would be concerned with the storage required, also we need to
trigger not only on Octavia distgit or upstream changes, all included
RPMs need to be checked checked for updates.
This could be simulated with dummy commits in distgit to force e.g.
nightly refresh but due to storage requirements, I'd keep image builds
outside trunk repos.
I have been doing some tests, and it looks like running diskimage-builder from a chroot is
not the best idea (it tries to mount some tmpfs and fails), so even if we solved the
storage issue it wouldn't work.
I think our best chance is to create a periodic job to rebuild the images (daily) then
upload them to images.rdoproject.org. This would be a similar approach to what we are
currently doing with containers.
The only drawback of this alternative is that we would be distributing the qcow2 images
instead of an RPM package, but we could still apply retention policies, and add some CI
jobs to test them if needed.
