Open Stack

Greetings,

I wanted to send out a summary email regarding some work that is still
developing and being planned to give interested parties time to comment and
prepare for change.

Project:
    Move tripleo periodic promotion jobs

Goal:
    Increase the cadence of tripleo-ci periodic promotion jobs in a way
that does not impact upstream OpenStack zuul queues and infrastructure.

Next Steps:
    The dependencies in RDO's instance of software factory are now complete
and we should be able to create a new a net new zuul queue in RDO infra for
tripleo-periodic jobs.  These jobs will have to run both multinode nodepool
and ovb style jobs and utilize RDO-Cloud as the host cloud provider.  The
TripleO CI team is looking into moving the TripleO periodic jobs running
upstream to run from RDO's software factory instance. This move will allow
the CI team more flexibility in managing the periodic jobs and resources to
run the jobs more frequently.

TLDR:
    There is no set date as to when the periodic jobs will move. The move
will depend on tenant resource allocation and how easily the periodic jobs
can be modified.  This email is to inform the group that changes are being
planned to the tripleo periodic workflow and allow time for comment and
preparation.

Completed Background Work:
    After long discussion with Paul Belanger about increasing the cadence
of the promotion jobs [1]. Paul explained infa's position and if he doesn't
-1/-2 a new pipeline that has the same priority as check jobs someone else
will. To summarize the point, the new pipeline would compete and slow down
non-tripleo projects in the gate even when the hardware resources are our
own.
To avoid slowing down non-tripleo projects Paul has volunteered to help
setup the infrastructure in rdoproject to manage the queue ( zuul etc). We
would still use rh-openstack-1 / rdocloud for ovb, and could also trigger
multinode nodepool jobs.
There is one hitch though, currently, rdo-project does not have all the
pieces of the puzzle in place to move off of openstack zuul and onto
rdoproject zuul. Paul mentioned that nodepool-builder [2] is a hard
requirement to be setup in rdoproject before we can proceed here. He
mentioned working with the software factory guys to get this setup and
running.
At this time, I think this issue is blocked until further discussion.
