[v1.2.1] Bug at release update when computenodes in creating
by Stefan Hoffmann Feb. 20, 2026

Feb. 20, 2026

Hi all, we found a bug with nova-compute nodes in creating since release v1.2.1 You will run into that issue when updating yaook to 1.2.1 or any newer version, if you have computenodes in state creating while updating the nova-compute-operator. We will try to build a fix, but maybe we just keep it as is. A workaround can be found in the issue[1] and after the upgrade and fixing once, the issue don't occur again. Also it is hopefully for the most environments possible to do the update when all nodes are finished with creation. If you want a fix, of cause, you can comment at the issue[1] or reply here. Best regards Stefan [1] https://gitlab.com/yaook/operator/-/issues/653

[Security Advisory] OSSA-2026-002
by Stefan Hoffmann Feb. 17, 2026

Feb. 17, 2026

Hi, today OpenStack announced that there is a CVE at nova, when using flat image backend [1]. We have further information at our Advisory [2]. If you DON'T have `use_cow_images=False` configured in nova.conf you should be not affected. To mitigate this issue, upgrade to yaook release v1.3.0 (will be released tomorrow) or pin the nova-compute image at nova-operator like described here[2] to registry.yaook.cloud/yaook/nova-compute-2025.1- ubuntu:4.1.183 Best regards Stefan [1] https://security.openstack.org/ossa/OSSA-2026-002.html [2] https://yaook.cloud/security-advisories-cve-2026-24708/

ALASCA Community Goal - SBOM
by Stefan Hoffmann Feb. 3, 2026

Feb. 3, 2026

Hi yaook folks, some days ago, we discussed with the ALASCA TSC what the community goal for 2026 could be. As already some projects are working on it, as well as yaook, we decided to create a SBOM for each project. The "official" goal is called: By the end of 2026, all of our ALASCA projects should have an SBOM or a tool to generate their SBOM.[1] I'm happy, that there is already some effort to implement that.

Participate with yaook at OpenStack PTG
by Stefan Hoffmann Feb. 3, 2026

Feb. 3, 2026

Hi, at the last OpenInfra summit or so, we asked, if it would be possible to take part at the OpenStack ProjectTeamGathering with our yaook project. We have the opportunity now to do so, I just would need to register us. Do you want to have such a meeting, where we discuss, what the next steps are for the project? As we are not forced to follow the OpenStack release cycle, we are quite free, what to do there and for what time frame to discuss stuff. But I would like to discuss open tasks at the SBOM and image build streamline process. Maybe there are other topics as well.
