[ironic][stable] Proposing EOL of ironic project branches older than Wallaby
by Jay Faulkner 02 Jun '23

02 Jun '23

Hi all, Ironic has a large amount of stable branches still in EM. We need to take action to ensure those branches are either retired or have CI repaired to the point of being usable. Specifically, I'm looking at these branches across all Ironic projects: - stable/queens - stable/rocky - stable/stein - stable/train - stable/ussuri - stable/victoria In lieu of any volunteers to maintain the CI, my recommendation for all the branches listed above is that they be marked EOL. If someone wants to volunteer to maintain CI for those branches, they can propose one of the below paths be taken instead: 1 - Someone volunteers to maintain these branches, and also report the status of CI of these older branches periodically on the Ironic whiteboard and in Ironic meetings. If you feel strongly that one of these branches needs to continue to be in service; volunteering in this way is how to save them. 2 - We seriously reduce CI. Basically removing all tempest tests to ensure that CI remains reliable and able to merge emergency or security fixes when needed. In some cases; this still requires CI fixes as some older inspector branches are failing *installing packages* in unit tests. I would still like, in this case, that someone volunteers to ensure the minimalist CI remains happy. My intention is to let this message serve as notice and a waiting period; and if I've not heard any response here or in Monday's Ironic meeting (in 6 days), I will begin taking action on retiring these branches. This is simply a start; other branches (including bugfix branches) are also in bad shape in CI, but getting these retired will significantly reduce the surface area of projects and branches to evaluate. I know it's painful to drop support for these branches; but we've provided good EM support for these branches for a long time and by pruning them away, we'll be able to save time to dedicate to other items. Thanks, Jay Faulkner

[magnum] Propose deprecation of Docker Swarm, CoreOS, fedora-ironic
by Jake Yip 28 Apr '23

28 Apr '23

Hi, Due to limited resources, Magnum team has decided to put most effort into supporting the most popular use case - Kubernetes on Fedora CoreOS. In light of that, we are seeking maintainers for the less well maintained drivers / COE - Docker Swarm, CoreOS and fedora-ironic drivers. The reasons are as follows: - Docker Swarm - It uses Fedora Atomic which has been EOL [1] - CoreOS - It is EOL [2] - fedora-ironic - Not tested, unsure if it is still working If anyone wants to take up maintenance of any of the above, we will be glad. Please let us know either through the ML or at the Magnum meetings. If there are no suitable maintainers, we will start the deprecation of these before end of Antelope. Regards, Jake [1]: https://projectatomic.io/blog/2019/11/fedora-atomic-host-nearing-eol/ [2]: https://www.redhat.com/en/technologies/cloud-computing/openshift/what-was-c… -- Jake Yip Magnum Team

Re: [all][stable][ptl] Propose to EOL Rocky series
by Elõd Illés 17 Apr '23

Hi, thanks for all the feedbacks from teams so far! @Zigo: Extended Maintenance process was created just for the same situation: to give space to interested parties to cooperate and keep things maintained even when stable releases are over their 'supported' lifetime. So it's good to see that there is interest in it! Unfortunately, with very old branches we've reached the state where gates can't be maintained and without a functional gate it's not safe to merge patches (yes, even security fixes) and they are just using resources (CI & maintainers' time). When gate is broken in such extent, then i think the community have to accept that it is not possible to merge patches confidently and needs to EOL that release. (Yes, it means that some vendors still have to do it for their own sake, testing it by their own, etc). Keeping things open in such state gives the false signal to vendors that 'it is maintained' however this is done without fully testing the changes. Another aspect is that code cannot be cleaned up until those old branches are still present (CI jobs, project configurations, etc) which gives pain for developers. So, however some vendors would appreciate probably to keep things open forever, for the community this is not beneficial and doable I think. Seeing that teams want to EOL their old branches is a proof that this is needed (unfortunately).

[all][ptg] Pre-PTG discussion: New Keystone Middleware Feature Supporting OAuth2.0 with External Authorization Service
by Hiromu Asahina 27 Mar '23

27 Mar '23

Hello Everyone, Recently, Tacker and Keystone have been working together on a new Keystone Middleware that can work with external authentication services, such as Keycloak. The code has already been submitted [1], but we want to make this middleware a generic plugin that works with as many OpenStack services as possible. To that end, we would like to hear from other projects with similar use cases (especially Ironic and Barbican, which run as standalone services). We will make a time slot to discuss this topic at the next vPTG. Please contact me if you are interested and available to participate.

[TripleO] Last maintained release of TripleO is Wallaby
by James Slagle 24 Mar '23

24 Mar '23

The team of TripleO developers, reviewers, and community have no plans to do another release of TripleO, or to continue maintaining the Zed release. This means the last maintained release of TripleO is Wallaby. The plan is to continue to maintain the train and wallaby branches of TripleO repositories under the openstack namespace. We plan to continue to run existing CI on those branches, although we anticipate reducing to a minimal set of jobs in the future. Going forward, the TripleO team expects to continue involvement in other OpenStack projects, and focus on different approaches to OpenStack deployment. The team is not aware of enough other community interest to continue to maintain the zed, master, and future branches of TripleO. Eventually, we will empty commit these branches with a pointer to Wallaby being the last release. If other interests do exist to maintain TripleO going forward, then those plans can adjust. TripleO does not plan on nominating a PTL in the current Bobcat election cycle. If a PTL-like contact is needed for train and wallaby maintenance, then someone will be nominated. I am also not sure how to reflect this project structure change within openstack/governance, and am looking for guidance on how to do so. This type of change did not seem to exactly fit within the concepts of inactive or retired projects. I can work on the patches for governance with some direction, if anyone can provide it. Thanks, and please let us know any questions or feedback about this plan. -- -- James Slagle --

[Openstack] Lack of Balance solution such as Watcher.
by Nguyễn Hữu Khôi 16 Mar '23

16 Mar '23

I am building a private cloud.Everything is ok. But I cannot find a way to balance vm when It have heavy load which cause impact other vm on the compute node. I found solutions such as Watcher and Leveller. But they need to be done manually. Watcher is not good because It need cpu metric such as cpu load in Ceilometer which is removed so we cannot use it. Leveller is good, but It is obsolete. Nguyen Huu Khoi

[security][ironic] Ironic + the VMT
by Jay Faulkner 10 Mar '23

10 Mar '23

Hey all, A recent topic at Ironic meetings the last couple of weeks have been around vulnerability management. Ironic has not been using the OpenStack VMT traditionally; for reasons that AFAICT are lost to time. Is there any reason Ironic should not be vulnerability-managed? Is the security team willing to have us? The only potential complication is that Ironic may receive reports for vendor libraries used by Ironic but not maintained by Ironic -- I was hoping there might already be some historical precedent for how we handle those; it can't be that unique to Ironic. What do folks think? Thanks, Jay Faulkner Ironic PTL TC Member
