I totally subscribe to the concerns around publishing binaries (under
any form), and the expectations in terms of security maintenance that it
would set on the publisher. At the same time, we need to have images
available, for convenience and testing. So what is the best way to
achieve that without setting strong security maintenance expectations
for the OpenStack community ? We have several options:
1/ Have third-parties publish images
It is the current situation. The issue is that the Kolla team (and
likely others) would rather automate the process and use OpenStack
infrastructure for it.
2/ Have third-parties publish images, but through OpenStack infra
This would allow to automate the process, but it would be a bit weird to
use common infra resources to publish in a private repo.
3/ Publish transient (per-commit or daily) images
A "daily build" (especially if you replace it every day) would set
relatively-limited expectations in terms of maintenance. It would end up
picking up security updates in upstream layers, even if not immediately.
4/ Publish images and own them
Staff release / VMT / stable team in a way that lets us properly own
those images and publish them officially.
Personally I think (4) is not realistic. I think we could make (3) work,
and I prefer it to (2). If all else fails, we should keep (1).
