Open Stack

To your point Steve, then I’d image that Kolla would have no objection to the introduction of other Openstack-namespace projects that provide alternative image formats, integration choices, or orchestration variances for those in the larger community who do not want to use Kolla images. All of the Kolla-x projects point to this one source of truth in the end. This results in large to the many projects falling under the Kolla umbrella: Kolla, Kolla-Mesos, Kolla-Ansible, Kolla-Kubernetes, Kolla-Salt, and I’d assume whatever else wants to consume Kolla, if things continue as they are.

My immediate ask is "what are the potential negative impacts to Kolla having so many projects under one mission”: fragmentation of goals, misunderstanding of mission, increased developer debt across each inter-twined project (cross-repo commits and reviews), complex gating requirements? #kolla has been a place of spirited debate with the recent addition of Kolla-Kubernetes, and I think some of this is the result of the problems I’m alluding to. It’s very difficult to preserve what Kolla is at it’s core, and in turn preserve the benefits of something like Kubernetes which has a Runtime Interface abstraction model. It’s a tough sell for the larger Openstack community, and this is a critical time for Openstack and CNCF interoperability; would you not agree?

I’m failing to see the benefits you mention outweighing what others might see as potential pitfalls. My viewpoint is not news to those in Kolla. I’ve expressed this in Kolla already, and this is why I’m disappointed when Kolla-Kuberntes drops Secs in favor of quicker ad-hoc IRC architecturally-focused discussions.

So my question now becomes; "How is Kolla addressing these issues, and what has Kolla been doing with the assistance of the Openstack Foundation to gain the confidence of those who are watching Kolla and looking for that next cool container project”?

So from my point of view, while I understand why project separation
makes sense in the long run, I will argue that at this moment it will
be hurtful for the project. Our community is still fairly integrated,
and I'd love to keep it this way a while longer. We haven't yet fully
cleaned up mess that split of kolla-ansible caused (documentation and
whatnot). Having small revolution like that again is something that
would greatly hinder our ability to deliver valuable project, and I
think for now that should be our priority.

To me, at least before we will have more than one prod-ready
deployment tool, separation of projects would be bad. I think project
separation should be a process instead of revolution, and we already
started this process by separating kolla-ansible repo and core team.
I'd be happy to discuss how to pave road for full project separation
without causing pain for operators, users and developers, as to me
their best interest should take priority.

Cheers,
Michal

I always believed we should have one core reviewer team responsible for all deliverables to avoid not just the appearance but the reality that each team would fragment the overall community of people working on Kolla containers and deployment tools. This is yet another reason I didn’t want to split the repositories into separate deliverables in the first place – since it further fragments the community working on Kolla deliverables.

If we break that into separate projects with separate PTLs, those projects may end up competing with each other (which isn’t happening now inside Kolla). I think competition is a good thing. In this case, I am of the opinion it is high time we end the competition on deployment tools related to containers and get everyone working together rather than apart. That is, unless those folks want to “work apart” which of course is their prerogative. I wouldn’t suggest merging teams today that are separate that don’t have a desire to merge. That said, Kolla is very warm and open to new contributors so hopefully no more new duplicate effort solutions are started.

We need consolidation around people working together, not division. Division around Kolla weakens Kolla specifically and doesn’t help out OpenStack all that much either.

Breaking a sub-community apart (in this case Kolla) into up to 4 different communities with 4 different PTLs sounds wrong to me.
