[openstack-helm] Inquiry: OpenStack-Helm Deployment in Production Environments
by Thamanna Farhath 04 Mar '25

04 Mar '25

Hello OpenStack Community, I hope this email finds you well. I am currently exploring OpenStack-Helm for deploying OpenStack and would like to understand its adoption in live production environments. Specifically, I am interested in knowing if any cloud providers have successfully deployed and are operating OpenStack using OpenStack-Helm in production. If there are any case studies, references, or experiences shared by operators who have implemented this deployment method, I would greatly appreciate any insights or guidance. Looking forward to your valuable input.

LXB Removal and OVN migration
by Ricardo Cano 04 Mar '25

04 Mar '25

Hello openstack-discuss, With the removal of the linuxbridge mechanism driver, has anyone successfully completed an in-place migrationfrom LinuxBridge to OVN? I did come across this https://www.jimmdenton.com/migrating-lxb-to-ovn/ and that looks good as a one-shoit while biting the bullet and taking a full outage. However, I was wondering if it was possible to run lxb and ovn side-by-side and cut them over, say one network at a time. This particular deployment was stood up using openstack-ansible back in the rocky days (now running antelope) and it appears that openstack ansible's default was lxb up until Zed. Any suggestions or recommendations on the best path forward? Also, will the dynamic routing agent work with ovn?

Dear Mentors, I have good experience in building openstack in multiple environments bare-metal, kolla-ansible and helm project for minimal deployment to good HA clusters. Now, I'm looking to get into code level and contribute to open-infra foundation. I'm not a someone beginner to coding, I have done programming in a good amount and hold a knowledge of paradigm and principles. Here's my github: https://github.com/jamesii-b I'm looking for mentor who can guide me what to do as a Contribution.. Even deploying first openstack is overwhelming on its own, Coding is more. Please have me. Trust me, I'll have utmost respect to your time and energy and get most of it. Knowledge I have: HPC, Openstack Deployment, Network & System, Parallel Programming, Python, Rust.

[telemetry] Nominate Juan Larriba to Telemetry core
by Takashi Kajinami 03 Mar '25

03 Mar '25

Hi, As some of you may know, current telemetry core team is quite small due to some cores shifting their focus recently. (As far as I see Matthius and I are the cores around the community recently). On the other hand we have seen revived interest in adding new features to telemetry services. To make sure these effort may receive appropriate feedback, I'd like to nominate Juan as a new Telemetry project core. He has been contributing the project for some time, and I've recently seen his consistent presence to review patches. In addition he volunteered to be a Telemetry PTL for the next cycle with his continued interest to keep the project active. If I don't hear any objections for one week, I'll add Juan to the group. Also, I'd like to take this chance to mention that we are really happy to see anyone who is interested in helping the project and appreciate any help to review proposed changes or maintain the project (so that we can invite them to the core group as well). Thank you, Takashi Kajinami -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

Installation guide: service_user_token clarification
by Eugen Block 03 Mar '25

03 Mar '25

Hi *, to me it's still a bit unclear, what exactly is required to properly set up service user tokens. The Yoga release notes point to the nova configuration guide [0], which only briefly describes the concept. But looking at the latest installation guide [1], there's also only a very short section with a link to the config page. But there's no mention of a service role that has to be created. If this is the default since Yoga, shouldn't the installation guides cover the entire process, including creating all necessary roles or the [keystone_authtoken] section that should probably contain "service_token_roles = service"? I currently find it quite confusing. Thanks! Eugen [0] https://docs.openstack.org/nova/latest/admin/configuration/service-user-tok… [1] https://docs.openstack.org/nova/2024.2/install/controller-install-ubuntu.ht…
