[openstack-dev] [tc][infra][release][security][stable][kolla][loci][tripleo][docker][kubernetes] do we want to be publishing binary container images?

What kolla's been discussing is having something like:
4.0.0-1, 4.0.0-2, 4.0.0-3, etc.
only keeping the most recent two. and then aliases for:
4.0.0 pointing to the newest.

This allows helm upgrade to atomically roll/forward back properly. If you drop releases, k8s can't properly do atomic upgrades. You will get inconsistent rollouts and will not know which containers are old and have the security issues. Knowing there is a newer -revision number also notifies you that you are running something old and need to update.

Yes, this.
