[tripleo][ironic][ansible][openstack-ansible] Ironic/Baremetal Ansible modules
by Sagi Shnaidman 21 Jan '20

21 Jan '20

Hi, all in the light of finding the new home place for openstack related ansible modules [1] I'd like to discuss the best strategy to create Ironic ansible modules. Existing Ironic modules in Ansible repo don't cover even half of Ironic functionality, don't fit current needs and definitely require an additional work. There are a few topics that require attention and better be solved before modules are written to save additional work. We prepared an etherpad [2] with all these questions and if you have ideas or suggestions on how it should look you're welcome to update it. We'd like to decide the final place for them, name conventions (the most complex one!), what they should look like and how better to implement. Anybody interested in Ansible and baremetal management in Openstack, you're more than welcome to contribute. Thanks [1] https://review.opendev.org/#/c/684740/ [2] https://etherpad.openstack.org/p/ironic-ansible-modules -- Best regards Sagi Shnaidman

[release] decentralising release approvals
by Mark Goddard 10 Jan '20

10 Jan '20

Hi, If this topic has been discussed many times already then someone please say so and we can leave it alone. As kolla PTL and ironic release liaison I've proposed a number of release patches recently. Generally the release team is good at churning through these, but sometimes patches can hang around for a while. Usually a ping on IRC will get things moving again within a day or so (thanks in particular to Sean who has been very responsive). Related to the recent discussion about decentralising stable branch maintenance, should we do this for releases too? To be clear, I'm proposing giving project teams more control over their own releases. I brought this up in IRC recently and there was a brief discussion. I suggested that releases are hard to undo, and Monty corrected me by saying they are impossible to undo. Still, if teams (or a subset of their members) had more ownership of their releases, they would become more familiar with the process, and the risk would be reduced. I'm not suggesting that release team should be disbanded - there is clearly work to do to maintain the tooling, determine and communicate the schedule, and more. But there's a lot of toil involved in checking and approving patches to the releases repo, and it's done by some of our most senior, busy colleagues. There are a number of checks that are performed automatically by the tooling and used to gate merges. I have a few questions for the release team about these reviews. * What manual checks do you do beyond those that are currently automated? * Could the above checks be automated? * What issues have you caught that were not caught by CI jobs? Hopefully I haven't offended anyone here. There's often more involved with these things than you first suspect. Cheers, Mark

[largescale-sig] Meeting summary and next actions
by Thierry Carrez 09 Jan '20

09 Jan '20

Hi everyone, The Large Scale SIG held a meeting earlier today. You can access the summary and logs of the meeting at: http://eavesdrop.openstack.org/meetings/large_scale_sig/2019/large_scale_si… This meeting was focused on immediate next steps on the two initial goals for the SIG. For the "Scaling within one cluster, and instrumentation of the bottlenecks" goal, after the holidays we will collect user stories of what happens (or what breaks first) as you scale up single clusters. We will also produce a first RFC draft for an oslo.metric blueprint, and learn more about the "Golden signals" concept. Standing TODOs: - all prepare a short description of what happens (what breaks first) when scaling up a single cluster - ttx to prepare etherpad and send ML thread asking for user scaling stories, to be posted after the end-of-year holidays - masahito to produce first draft for the oslo.metric blueprint - all learn more about golden signals concept as described in https://landing.google.com/sre/book.html For the "Document large scale configuration and tips &tricks" goal we will start collecting relevant articles and blogposts. We agreed that in order to properly document large scale configuration defaults, we should probably both patch existing docs and create new documentation. Standing TODOs: - all add links to relevant articles around large scale openstack (if you find any) to the etherpad - oneswig to follow up with Scientific community to find such articles - amorin to start a thread on documenting configuration defaults for large scale, introduce the "mixture of both" tactic The next meeting will happen on January 15, at 9:00 UTC on #openstack-meeting. Cheers, -- Thierry Carrez (ttx)

[all][neutron][neutron-vpnaas] Maintainers needed
by Slawek Kaplonski 06 Jan '20

06 Jan '20

Hi, Over the past couple of cycles we have noticed that new contributions and maintenance efforts for neutron-vpnaas were almost non existent. This impacts patches for bug fixes, new features and reviews. The Neutron core team is trying to at least keep the CI of this project healthy, but we don’t have enough knowledge about the details of the neutron-vpnaas code base to review more complex patches. During the PTG in Shanghai we discussed that with operators and TC members during the forum session [1] and later within the Neutron team during the PTG session [2]. During these discussions, with the help of operators and TC members, we reached the conclusion that we need to have someone responsible for maintaining project. This doesn’t mean that the maintainer needs to spend full time working on this project. Rather, we need someone to be the contact person for the project, who takes care of the project’s CI and review patches. Of course that’s only a minimal requirement. If the new maintainer works on new features for the project, it’s even better :) If we don’t have any new maintainer(s) before milestone Ussuri-2, which is Feb 10 - Feb 14 according to [3], we will need to mark neutron-vpnaas as deprecated and in “V” cycle we will propose to move the project from the Neutron stadium, hosted in the “openstack/“ namespace, to the unofficial projects hosted in the “x/“ namespace. So if You are using this project now, or if You have customers who are using it, please consider the possibility of maintaining it. Otherwise, please be aware that it is highly possible that the project will be deprecated and moved out from the official OpenStack projects.

[oslo][kolla][requirements][release][infra] Hit by an old, fixed bug
by Radosław Piliszek 06 Jan '20

06 Jan '20

Hi Folks, as the subject goes, my installation has been hit by an old bug: https://bugs.launchpad.net/oslo.messaging/+bug/1828841 (bug details not important, linked here for background) I am using Stein, deployed with recent Kolla-built source-based images (with only slight modifications compared to vanilla ones). Kolla's procedure for building source-based images considers upper constraints, which, unfortunately, turned out to be lagging behind a few releases w.r.t. oslo.messaging at least. The fix was in 9.7.0 released on May 21, u-c still point to 9.5.0 from Feb 26 and the latest of Stein is 9.8.0 from Jul 18. It seems oslo.messaging is missing from the automatic updates that bot proposes: https://review.opendev.org/#/q/owner:%22OpenStack+Proposal+Bot%22+project:o… Per: https://opendev.org/openstack/releases/src/branch/master/doc/source/referen… this upper-constraint proposal should be happening for all releases. I would be glad if someone investigated why it happens(/ed) and audited whether other OpenStack projects don't need updating as well to avoid running on old deps when new are awaiting for months. :-) Please note this might apply to other branches as well. PS: for some reason oslo.messaging Stein release notes ( https://docs.openstack.org/releasenotes/oslo.messaging/stein.html ) are stuck at 9.5.0 as well, this could be right (I did not inspect the sources) but I am adding this in PS so you have more things to correlate if they need be. -yoctozepto

[cloudkitty] Stepping down from PTL
by Luka Peschke 06 Jan '20

06 Jan '20

Hi all, I'm moving to a new position that doesn't involve OpenStack, and won't leave me the required time to be Cloudkitty's PTL. This is why I have to step down from the PTL position. jferrieu will take my position for the end of the U cycle (he's been a major contributor recently), with the help of huats, who's been the Cloudkitty PTL before me, and has been around in the community for a long time. I've been the PTL for two and a half cycles, and I think that it is a good thing for the project to take a new lead, with a new vision. I'm grateful for my experience within the OpenStack community. Thanks, -- Luka Peschke (peschk_l)
