I think it's not a bad idea to message "you are responsible for
archving your containers". Do that, combine it with good toolset that
helps users determine versions of packages and other metadata and
we'll end up with something that itself would be greatly appreciated.

Few potential user stories.

I have OpenStack <100 nodes and need every single one of them, hence
no CI. At the same time I want to have fresh packages to avoid CVEs. I
deploy kolla with tip-of-the-stable-branch and setup cronjob that will
upgrade it every week. Because my scenerio is quite typical and
containers already ran through gates that tests my scenerio, I'm good.

Another one:

I have 300+ node cloud, heavy CI and security team examining every
container. While I could build containers locally, downloading them is
just simpler and effectively the same (after all, it's containers
being tested not build process). Every download our security team
scrutinize contaniers and uses toolset Kolla provides to help them.
Additional benefit is that on top of our CI these images went through
Kolla CI which is nice, more testing is always good.

And another one

We are Kolla community. We want to provide testing for full release
upgrades every day in gates, to make sure OpenStack and Kolla is
upgradable and improve general user experience of upgrades. Because
infra is resource constrained, we cannot afford building 2 sets of
containers (stable and master) and doing deploy->test->upgrade->test.
However because we have these cached containers, that are fresh and
passed CI for deploy, we can just use them! Now effectively we're not
only testing Kolla's correctness of upgrade procedure but also all the
other project team upgrades! Oh, it seems Nova merged something that
negatively affects upgrades, let's make sure they are aware!

And last one, which cannot be underestimated

I am CTO of some company and I've heard OpenStack is no longer hard to
deploy, I'll just download kolla-ansible and try. I'll follow this
guide that deploys simple OpenStack with 2 commands and few small
configs, and it's done! Super simple! We're moving to OpenStack and
start contributing tomorrow!

Please, let's solve messaging problems, put burden of archiving on
users, whatever it takes to protect our community from wrong
expectations, but not kill this effort. There are very real and
immediate benefits to OpenStack as a whole if we do this.

Cheers,
Michal
