Thanks for sending this out Attila..

So after some discussion with David and others I wanted to spell out a bit
of a nuance that may cause this to take a little bit more time and effort.

The original plan was to build and test containers as part of the rdo
master pipeline [1].  We were on track to complete this work in the next
couple days.
However what we realized was that rdo has to feed tripleo container builds
for tripleo promotions, and tripleo promotions are always done on a random
new delorean hash.
There is no way to determine which hash tripleo will pick up, and therefore
no way to ensure the containers and rpms are at the exact same versions.
It's critical that rpms and containers are built using the exact same repos

It is also good form and upstream policy for the tools, jobs and build
artifacts to be created upstream.

So the new plan is to build and test containers in the tripleo periodic
jobs that are used for the tripleo promotions.
When the containers pass a build they will be uploaded to the container
registry in rdo with a tag, e.g. current-tripleo.

The main point of this email is to levelset expectations that it will take
a little more time to get this done upstream.
I am very open to hearing suggestions, comments and critques of the new
high level plan.

Thank you!
