So issue is, I know of few other openstacks on k8s and everyone does that slightly differently. So far we lack proof points and real world data to determine best approaches to stuff. This is still not-to-well researched field. Right now it's mostly opinions and assumptions. We're not ready to make document without having a flame war around it;) Not enough knowledge in our collective brains.
Awesome input, thanks.
As for Kolla-k8s we are still deep in development, so we are free to take best course of action we know of. We don't have any technical debt now. Current state of stuff represents what we thing is best approach.
I wonder if we can start writing these assumptions down and update them as we go. I don't expect you to do it, I'm happy to help with this. We could put it in kolla-k8s docs if that makes sense to other kolla-k8s folks. I'll probably start pinging you guys on IRC with questions so I can help writing this down.
There is also part that k8s is constantly growing and it lacks certain features that created these issues in the first place, if k8s solves them on their side, that will affect decision on our side.
Thanks a lot, Michal. This is indeed the kind of info I was looking for and where I'd love to start from. Flavio

If you are running k8s, you still run docker:)I know this (although, if we really want to nitpick you could technically use something else than docker :P). In my email I mentioned that I'm interested in documenting how one would deploy OpenStack on kubernetes, which is likely different from how you'd deploy OpenStack on docker (or any other container runtime).Kolla-kubernetes is a part of Big Tent, is project developed by Kolla community and we're close to our big showdown:) Come over to our session in Barcelona, in the meantime I suggest you look at https://github.com/openstack/kolla-kubernetes and join us at #openstack-kollaThakns for the info. As I mentioned in my email, I know kolla-kubernetes, I've reviewed some specs and patches, etc. I am, however, interested in something different which is how you'd deploy OpenStack on k8s. Is kolla-kubernetes doing this the right way? Is there a better way to do it? These are the kind of things I'd love to document. I know some OPs have contributed to kolla-kubernetes too.

More specifically, I've been looking into the tools that allow for deploying OpenStack on containers, which is what I'm the most interested in right now as part of the TripleO efforts. I'm familiar with the Kolla project and the tools managed by this team. In fact, TripleO currently uses kolla images for the containerized nova-compute deployment. I am, however, looking beyond a docker based deployment. I'd like to explore in more depth a Kubernetes based deployment of OpenStack. I'm familiar with both kolla-kubernetes and fuel-ccp, their structure and direction*. Both projects have now advanced a bit in their implementations and made some decisions. As someone that started looking into this topic just recently, I'd love to see our communities collaborate more wherever possible. For example, it'd be great to see us working on a reference architecture for deploying OpenStack on kubernetes, letting the implementation details aside for a bit. I'd assume some folks have done this already and I bet we can all learn more from it if we work on this together. So, let me go ahead and ask some further questions here, I might be missing some history and/or context: - Is there any public documentation that acts as a reference architecture for deploying OpenStack on kubernetes? - Is this something the architecture working group could help with? Or would it be better to hijack one of kolla meetings? The restult I'd love to see from this collaboration is a reference architecture explaining how OpenStack should be run on Kubernetes.At this moment, fuel-ccp-* is an experiment, it's not under governance, there is no expectation of any releases, there are no specs or docs that i know of. So kolla/kolla-kubernetes is probably the best accumulator of kubernetes knowledge specifically about running openstack. Note that tcpcloud folks may also have something, but haven't seen any public information or reference architecture from them. Definitely don't know of any plans from that team as well to open up and share.Thanks in advance. I look forward to see us collaborate more on this area, Flavio * thanks to all fuel and kolla contributors that helped me understand better the work in each of these projects and the direction they are headed . -- @flaper87 Flavio Percoco __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-devThanks, Dims -- Davanum Srinivas :: https://twitter.com/dims __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev__________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev-- @flaper87 Flavio Percoco __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev__________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
