I think this is the gist of the concern and I'd like us to focus on it.
As someone that used to consume these images from kolla's dockerhub account
directly, I can confirm they are useful. However, I do share Doug's concern and
the impact this may have on the community.
From a release perspective, as Doug mentioned, we've avoided releasing projects
in any kind of built form. This was also one of the concerns I raised when
working on the proposal to support other programming languages. The problem of
releasing built images goes beyond the infrastructure requirements. It's the
message and the guarantees implied with the built product itself that are the
concern here. And I tend to agree with Doug that this might be a problem for us
as a community. Unfortunately, putting your name, Michal, as contact point is
not enough. Kolla is not the only project producing container images and we need
to be consistent in the way we release these images.
Nothing prevents people for building their own images and uploading them to
dockerhub. Having this as part of the OpenStack's pipeline is a problem.
P.S: note this goes against my container(ish) interests but it's a
