Network demand for controller nodes
by William Muriithi 10 Jul '24

10 Jul '24

Hello, Does anyone know if controller nodes are demanding on network needs? I have a situation where I don't have enough 10GB/s port in the switch. Would a cluster be network constrained if I have three controllers using 1GB/s connections and the execution and storage nodes are on 10GB/s connections? Does the VM traffic ever transverse the controller's network cards? In another word, is there a valid requirement for 10GB/s on openstack controllers? Regards, William

[skyline][tc] Graduating skyline out of the "Emerging Projects" list
by Goutham Pacha Ravi 10 Jul '24

10 Jul '24

Hi, We were discussing in a recent TC meeting that Skyline seems to be ready to lose the "Emerging project" tag [1]. The arguments supporting it's graduation are: - The project is actively maintained, and has had consistent releases since the Zed release [2][3][4][5] - The project is being used in production cloud deployments [6] - Operators have requested skyline's inclusion in deployment and configuration management projects [7][8] Wu Wenxiang / Skyline team - is this assessment correct? If yes, are there any objections to removing Skyline from [1]? If it helps, the project team can re-assess the OpenStack project requirements we have [9] and work on any deficiencies. Thanks, On behalf of the OpenStack TC, Goutham Pacha Ravi OpenStack TC Chair [1] https://governance.openstack.org/tc/reference/emerging-technology-and-inact… [2] https://releases.openstack.org/zed/#skyline-apiserver [3] https://releases.openstack.org/antelope/#skyline-apiserver [4] https://releases.openstack.org/bobcat/#skyline-apiserver [5] https://releases.openstack.org/caracal/#skyline-apiserver [6] https://governance.openstack.org/tc/user_survey/analysis-2023.html#how-do-y… [7] https://review.opendev.org/q/topic:%22osa/skyline%22 [8] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack…

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2024.2/R-12)
by Goutham Pacha Ravi 09 Jul '24

09 Jul '24

Hello Stackers, Time flies, we're over halfway through our 2024.2 (Dalmatian) release cycle! This second half is usually chock-full of release deadlines, specification and code freezes, and more release action [1]. The past week was a short work week for many folks in the Technical Committee due to local holidays, so this update will be brief. Hervé Beraud (hberaud) and Mike Bayer (zzzeek) joined us at the TC's video meeting last week, and they took us through the goal proposal to remove eventlet from OpenStack [2][3][4][5][6]. The meeting was well attended, and it involved a walkthrough of SQLAlchemy, where zzzeek presented how it supports asyncio and a library that allows non-async definitions to invoke awaitables inside an asyncio application. We didn't merge any new governance proposals this week, but several are in review as noted below. === Weekly Meeting === The weekly meeting was held simultaneously on video and IRC. Please check out the recording posted to the TC's YouTube channel [7] as well as the meeting log on eavesdrop [8]. We have new governance proposals that concern Freezer and Monasca, the two projects that were marked "inactive" during the last release cycle. We discussed providing the Skyline team instructions and time to graduate from being an "emerging" project. The TC reiterated its commitment to ensure that all decisions are made asynchronously and recorded on Gerrit to involve community members in different time zones. The rest of the meeting was focused on the eventlet removal discussion. It was a very informative presentation that I'd recommend all OpenStack maintainers review. We took a note to time-box the reviews on the goal proposal. I'd like to request reviews and any strong objections to be expressed on the proposal as soon as possible. The next Technical Committee meeting is today, 2024-07-09 at 1800 UTC! The meeting will be hosted on OFTC's #openstack-tc channel, and the agenda has been posted to the Meetings Wiki Page [9]. Please consider joining us! === Governance Proposals === Remove Eventlet From Openstack | https://review.opendev.org/c/openstack/governance/+/902585 Update criteria for the inactive projects to become active again | https://review.opendev.org/c/openstack/governance/+/921500 Remove Monasca from inactive list | https://review.opendev.org/c/openstack/governance/+/923466 Transition Watcher project to DPL | https://review.opendev.org/c/openstack/governance/+/923583 Inactive state extensions: Freezer | https://review.opendev.org/c/openstack/governance/+/923441 Retire Kuryr-Kubernetes and Kuryr-Tempest-Plugin | https://review.opendev.org/c/openstack/governance/+/922507 Update to include docs and miscellaneous repos for AC status | https://review.opendev.org/c/openstack/governance/+/915021 Adding a rule to manage the affiliation diversity requirement in the TC | https://review.opendev.org/c/openstack/governance/+/922512 === Upcoming Events === 2024-08-14: Nominations open for 2025.1 OpenStack PTL+TC elections 2024-08-29: Dalmatian-3 milestone Thank you very much for reading!

[ironic] Docs audit complete; results available
by Jay Faulkner 09 Jul '24

09 Jul '24

Hi all, Two PTGs ago, Ironic contributors had a topic about documentation -- we acknowledged our documentation was at times comprehensive, but at times incomprehensible :). This led us to enlist a professional technical writer, Dave Welsch, to assist. Dave has been working over the last few months to get feedback from Ironic users and contributors, as well as auditing our documentation and has put his final findings here: https://docs.google.com/document/d/1e9URuPHKNTx5QXdkCFAzsS0EAAxPJ-xQC4BEpDw… . Actionable bugs were a desired outcome of this, which was achieved. We filed several bugs against Ironic, tagged "docs-audit-2024" -- you can see the list here: https://bugs.launchpad.net/ironic/+bugs?field.tag=docs-audit-2024. I know that identifying issues is only part of the work needed; but it's our hope that by breaking this down and creating a path towards better docs, we'll be able to make it a less daunting task for contributors -- possibly even doable by folks from an outreachy-like program. Thanks for those who participated in this process. Feel free to reach out here if you have any questions, or to me privately. Thanks, Jay Faulkner

How to setup filters into oslo_notification/cinder
by Helder Ardachnikoff Gomes 09 Jul '24

09 Jul '24

I am working on a project with cinder and we keep listening to events from cinder through oslo messaging. We wish to set up cinder config in order to not receive events with the following event_type: volumes.exist. I read on chatgpt that I could setup my config like that: [oslo_messaging_notifications] driver = messagingv2 topics = notifications notification_format = both notification_filters = -volume.exist But, I am not quite confident about that, may someone help me ? -- _‘Esta mensagem é direcionada apenas para os endereços constantes no cabeçalho inicial.

[Neutron] Is there a way to work around "External network not reachable from subnet" by setting a static route?
by Florian Haas 08 Jul '24

08 Jul '24

Hi everyone, here's a question I've been chewing on for some time. Please bear with me while I illustrate the background. 1. Suppose you have a regular (internal) Neutron network, subnet, and router. You now plug the subnet into the router and set an external gateway. You then create a port on the subnet. You associate a floating IP with that port. All is well. 2. Suppose instead you do plug the subnet into the router, but you don't set an external gateway on it. You try to associate a floating IP with that port. This creates a BadRequest because: "External network <uuid> is not reachable from subnet <uuid>". 3. Suppose instead you do set an external gateway on the router, but you don't connect the subnet to it. Again, you try to associate a floating IP with that port. This also creates a BadRequest because: "External network <uuid> is not reachable from subnet <uuid>". So far, so good. Up to this point, everything is behaving according to intuitive expectations. Now suppose we have * the external network, * an "outer" internal network, * a Neutron router connecting the two (that is, the router has the external network as its gateway, and has an interface to the "outer" subnet), * an "inner" internal network, * a Nova server (let's call that the "gateway"), which connects the "inner" and "outer" networks, a * another Nova server (the "worker") that sits on the "inner" network. (Suppose, for the sake of discussion, that the "gateway" runs some kind of web application firewall or other virtual security appliance, and the "worker" is a general-purpose Linux instance.) Now I can give the Neutron router a static route so that traffic to the "inner" network uses the "gateway" as its nexthop. Provided the "gateway" does its forwarding correctly, this means that the "worker" has internet connectivity via the "gateway" (which, in turn, achieves this via the router). This, too, works fine for outbound connections originating with the "worker". If I now want to assign a floating IP to the "worker", then routing-wise there really should be no problem: the router should take care of SNAT/DNAT, it would translate the floating IP into a private IP on the "inner" network, would consult its routing table, and throw packets for that "inner" network to the "gateway" to handle, per the static route that's been set. But when I try to associate a floating IP to the "worker" in this scenario, I *still* get the "External network not reachable from subnet" error, because the associated internal check[1] does not take the existing static route into account. This appears to have been an issue in other contexts as well: the defunct Tricircle project appears to have worked around this limitation via a service plugin that just omitted that check.[2] Now my questions are these: 1. Shouldn't this be fixed in core, instead? It would seem to me like the default check is too simplistic, but I might be missing something. 2. Is there a way to make this check take static routes into account, other than providing a service plugin like Tricircle used to do? Thanks! Cheers, Florian References: [1] get_router_for_floatingip(): https://opendev.org/openstack/neutron/src/commit/ebed620aafdff75a05fb5d42ad… [2] get_router_for_floatingip(): https://opendev.org/openstack/tricircle/src/commit/8db8fb30f5757c46a953962d…
