Hi Murilo,
Hi, Karanbir.
Thanks for replying me. And pardon me if I am flooding you with too many questions, I just want to have topics organized in my mind.
This might be better to host on an office hours session perhaps, and post followup notes to this thread - the ask from your side is quite vast, and email might take a while to get traction. But a few pieces of info here :
Definitely. I will get in touch with you in one of the office hours sessions ahead. Meanwhile, I think we can keep discussions here as well -- web archives are easier to search than IRC logs.

This would be a fantastic goal to aim for. The CentOS CI infrastructure is evolving at the moment, and this is certainly a good time to get involved in that process.
That is great. Can you share more details about what is changing, e.g. moving to new facility, hardware upgrade, etc?

The docker images etc might be a good place to start from, but there is no infra or process in place to handle these in a sane manner from our side.
I would like to understand the details behind infra and process.
As to infra, is it a collocation issue, i.e. no room for more servers? Or is it an issue of lack of POWER hardware? The latter seems to be easier to get addressed.
As to process, is it something that is already being worked by any SIG? Perhaps SIG Core or SIG Cloud? Who is the owner of this process?
So I think the first steps we should likely kick off with is making sure we have the ppc64 and ppc64le targets available and setup in cbs.centos.org while we talk about how and where and when we can work on the other bits.
It is not clear to me what is the relationship between hosts in cbs.centos.org and ci.centos.org.
My understanding is that cbs hosts are only used by koji to build packages for the cbs system; and that ci hosts are used to run the Jenkins jobs, which, eventually, allocate and release machines from the Duffy pool via admin.ci.centos.org. Did I get it correctly?
I can see that 2 ppc64 nodes are setup for cbs (http://cbs.centos.org/koji/hosts). Is the plan to setup more ppc64 nodes on cbs.centos.org?
eg. even if we were building the cloud images, there is no place to test them.
My vision is that we can mimic some of the amd64 jobs, e.g. https://ci.centos.org/view/CentOS-Core-QA/job/CentOS-Core-QA-t_docker-c6-64/, to build and test docker images on ppc64le as well.
With CentOS 7.3, it is now possible to build, run, and test docker images in CentOS guest.
w.r.t the docker images, I think it might be good to engage into the CentOS Container Pipeline and handle it that way.
That would also require ppc64 hardware to run the CentOS Container Pipeline jobs.
Is there any room to creating more ppc64le guests and adding them to ci.centos.org?
Thanks!
