[all] Proposed Wallaby cycle schedule
by Sean McGinnis 20 Aug '20

20 Aug '20

Hey everyone, The Victoria cycle is going by fast, and it's already time to start planning some of the early things for the Wallaby release. One of the first steps for that is actually deciding on the release schedule. Typically we have done this based on when the next Summit event was planned to take place. Due to several reasons, we don't have a date yet for the first 2021 event. The current thinking is it will likely take place in May (nothing is set, just an educated guess, so please don't use that for any other planning). So for the sake of figuring out the release schedule, we are targeting a release date in early May. Hopefully this will then align well with event plans. I have a proposed release schedule up for review here: https://review.opendev.org/#/c/744729/ For ease of viewing (until the job logs are garbage collected), you can see the rendered schedule here: https://0e6b8aeca433e85b429b-46fd243db6dc394538bd0555f339eba5.ssl.cf1.rackc… There are always outside conflicts, but I think this has aligned mostly well with major holidays. But please feel free to comment on the patch if you see any major issues that we may have not considered. Thanks! Sean

[tripleo] Moving tripleo-ansible-inventory script to tripleo-common?
by Cédric Jeanneret 20 Aug '20

20 Aug '20

Hello there! I'm wondering if we could move the "tripleo-ansible-inventory" script from the tripleo-validations repo to tripleo-common. The main motivation here is to make things consistent: - that script calls content from tripleo-common, nothing from tripleo-validations. - that script isn't only for the validations, so it makes more sense to install it via tripleo-common - in fact, we should probably push that inventory thing as an `openstack tripleo' sub-command, but that's another story So, is there any opposition to this proposal? Cheers, C. -- Cédric Jeanneret (He/Him/His) Sr. Software Engineer - OpenStack Platform Deployment Framework TC Red Hat EMEA https://www.redhat.com/

[neutron] Disable dhcp drop rule
by Eugen Block 20 Aug '20

20 Aug '20

Hi *, we recently upgraded our Ocata Cloud to Train and also switched from linuxbridge to openvswitch. One of our instances within the cloud works as DHCP server and to make that work we had to comment the respective part in this file on the compute node the instance was running on: /usr/lib/python2.7/site-packages/neutron/agent/linux/iptables_firewall.py Now we tried the same in /usr/lib/python3.6/site-packages/neutron/agent/linux/openvswitch_firewall/firewall.py /usr/lib/python3.6/site-packages/neutron/agent/linux/iptables_firewall.py but restarting openstack-neutron-openvswitch-agent.service didn't drop that rule, the DHCP reply didn't get through. To continue with our work we just dropped it manually, so we get by, but since there have been a couple of years between Ocata and Train, is there any smoother or better way to achieve this? This seems to be a reoccuring request but I couldn't find any updates on this topic. Maybe someone here can shed some light? Is there more to change than those two files I mentioned? Any pointers are highly appreciated! Best regards, Eugen

OpenStack with Nginx
by HARISH KUMAR Ivaturi 19 Aug '20

19 Aug '20

Hi I am Harish Kumar, Master Student at BTH, Karlskrona, Sweden. I am working on my Master thesis at BTH and my thesis topic is Performance evaluation of OpenStack with HTTP/3. I have successfully built curl and nginx with HTTP/3 support and I am performing some commands using curl for generating tokens so i could access the services of OpenStack. OpenStack relies with the Apache web server and I could not get any results using Nginx HTTP/3 . I would like to ask if there is any official documentation on OpenStack relying with Nginx?, I have searched in the internet reg. this info but could not get any, I would like to use nginx instead of apache web server , so I could get some results by performing curl and commands and nginx web server (with http/3 support). Please let me know and if there is any content please share with me. I hope you have understood this. It would be helpful for my Master Thesis. BR Harish Kumar

[upstream-institute] Virtual training sign-up and planning
by Ildiko Vancsa 19 Aug '20

19 Aug '20

Hi mentors, I’m reaching out to you as the next Open Infrastructure Summit is approaching quickly so it is time to start planning for the next OpenStack Upstream Institute. As the next event will be virtual we will need to re-think the training format and experience to make sure our audience gets the most out of it. I created a new entry on our training occasions wiki page here: https://wiki.openstack.org/wiki/OpenStack_Upstream_Institute_Occasions#Virt… Please __sign up on the wiki__ if you would like to participate in the preparations and running the virtual training. As it is still vacation season I think we can target the last week of August or first week of September to have the first prep meeting and can collect ideas here or discuss them on the #openstack-upstream-institute IRC channel on Freenode in the meantime. Please let me know if you have any questions or need any help with signing up on the wiki. Thanks and Best Regards, Ildikó

[neutron][ops] API for viewing HA router states
by Mohammed Naser 19 Aug '20

19 Aug '20

Hi all, Over the past few days, we were troubleshooting an issue that ended up having a root cause where keepalived has somehow ended up active in two different L3 agents. We've yet to find the root cause of how this happened but removing it and adding it resolved the issue for us. As we work on improving our monitoring, we wanted to implement something that gets us the info of # of active routers to check if there's a router that has >1 active L3 agent but it's hard because hitting the /l3-agents endpoint on _every_ single router hurts a lot on performance. Is there something else that we can watch which might be more productive? FYI -- this all goes in the open and will end up inside the openstack-exporter: https://github.com/openstack-exporter/openstack-exporter and the Helm charts will end up with the alerts: https://github.com/openstack-exporter/helm-charts Thanks!

[cinder][ops] "Berlin" 2020 Virtual Forum - Cinder brainstorming
by Brian Rosmaita 19 Aug '20

19 Aug '20

This message is aimed at anyone with an interest in the OpenStack Block Storage Service, whether as an operator, a user, or a developer. Like all the other teams, Cinder would like to get feedback from operators and users about the current state of the software, get some ideas about what should be in the next release, and have some strategic discussion about The Future. So if you have some ideas you'd like to be considered, feel free to propose a topic: https://etherpad.opendev.org/p/2020-Wallaby-cinder-brainstorming You only need to add a sentence or two describing your topic and it doesn't have to be very polished, so if you have an idea, just go to the etherpad and slap it down now while you're thinking about it. The deadline for proposals to the Foundation is 14 September, so if you could get your idea down on the etherpad before the Cinder weekly meeting on Wednesday 9 September 14:00 UTC, that will give the Cinder team time to look them over. thanks! brian

[tripleo][ci] container pulls failing
by Wesley Hayutin 19 Aug '20

19 Aug '20

FYI... If you find your jobs are failing with an error similar to [1], you have been rate limited by docker.io via the upstream mirror system and have hit [2]. I've been discussing the issue w/ upstream infra, rdo-infra and a few CI engineers. There are a few ways to mitigate the issue however I don't see any of the options being completed very quickly so I'm asking for your patience while this issue is socialized and resolved. For full transparency we're considering the following options. 1. move off of docker.io to quay.io 2. local container builds for each job in master, possibly ussuri 3. parent child jobs upstream where rpms and containers will be build and host artifacts for the child jobs 4. remove some portion of the upstream jobs to lower the impact we have on 3rd party infrastructure. If you have thoughts please don't hesitate to share on this thread. Very sorry we're hitting these failures and I really appreciate your patience. I would expect major delays in getting patches merged at this point until things are resolved. Thank you!

[cloudkitty][tc] Cloudkitty abandoned?
by Sean McGinnis 19 Aug '20

19 Aug '20

Posting here to raise awareness, and start discussion about next steps. It appears there is no one working on Cloudkitty anymore. No patches have been merged for several months now, including simple bot proposed patches. It would appear no one is maintaining this project anymore. I know there is a need out there for this type of functionality, so maybe this will raise awareness and get some attention to it. But barring that, I am wondering if we should start the process to retire this project. From a Victoria release perspective, it is milestone-2 week, so we should make a decision if any of the Cloudkitty deliverables should be included in this release or not. We can certainly force releases of whatever is the latest, but I think that is a bit risky since these repos have never merged the job template change for victoria and therefore are not even testing with Python 3.8. That is an official runtime for Victoria, so we run the risk of having issues with the code if someone runs under 3.8 but we have not tested to make sure there are no problems doing so. I am hoping this at least starts the discussion. I will not propose any release patches to remove anything until we have had a chance to discuss the situation. Sean
