[Zun] Docker in rootless mode
by Francesco Di Nucci 14 Mar '24

14 Mar '24

Hello, I am working on a 2023.2 instance to install Zun. While we're still in the design phase, I was wondering if it is possible to run Docker as a non-root user together with Kata Containers for enhanced security. Has anyone tried this solution? Regards Francesco Di Nucci

What deployment tools do you use? What do you like in them?
by Ruslanas Gžibovskis 14 Mar '24

14 Mar '24

Hi team, Could you, please, share your opinion and your experience with deployment methods. Also what are the tools you use? I have some deployments running TripleO tool. What I like is that we can deploy on empty servers and customizable OpenStack Installation. Sadly TripleO stopped working on new releases last year. Question: Which deployment method you would recommend which would support deploying on empty servers? My plan is to use CentOS Stream as base OS. My setup: 3x controller and 10+ computes. All with generic things except cinder, I do not have volumes and telemetry. But this year I need to add SR-IOV and some computes with RT kernels. Suggestions? My research: OSP-ansible - looks like it could deploy without containerization (I find it as a benefit). (could someone share sample config you use?) Kolla-ansible - looks like old time here and most used? (could someone share sample config you use?) But all above are deploying on existing OS. Tho I have found the Kayobe, quite new to me, have you tried? How multi-controller and multicompute deployment config looks like? Thank you for your opinion or sharing your experience with the tools you use. -- Ruslanas Gžibovskis +370 6030 7030

[Cinder] Storage not detected when instance boots from ISO
by Francesco Di Nucci 13 Mar '24

13 Mar '24

Hello, premised that probably I am misunderstanding default behavior, I'm experiencing a weird issue with storage/volumes: * Cinder storage has only a NFS backend, with "cinder.volume.drivers.nfs.NfsDriver" driver * When I launch an instance through Horizon from a QCOW2 cloud image and with an associated volume, everything is ok (instances start, changes to the instance are persistent and remain through reboots etc) * But if I launch an instance from an ISO (CentOS, Debian, Ubuntu - DVD or minimal, seems to be OS-independent) and with an associated volume, I can use the installer through the noVNC console but it does not detect disks. Even if the volume is attached, the OS booted from ISO does not report/find it, and the installation can't proceed Is this normal/default behavior or is something wrong with my install? Best regards Francesco Di Nucci

Security Group Rules on Octavia Amphorae
by Kees Meijs | Nefos 13 Mar '24

13 Mar '24

Hello list, When creating a new load balancer using Octavia, I noticed the VIP network port gets assigned a dynamic created Security Group. The Security Group does not contain a rule allowing ICMP, therefore the VIP not being "pingable". Other than harder diagnostics, it could pose PMTU issues and such. Is it maybe possible to either just enable ICMP, or maybe template the dynamic Security Groups? Thanks in advance! Cheers, Kees

[swift] Increase part power on account/container ring
by Thiago De Moraes Teixeira 13 Mar '24

13 Mar '24

Morning, Here we have a cluster with Accounts/Containers ring with part power 8 and our Objects ring with part power 20 (builted later). Now we want to migrate the 'old' Accounts/Containers ring to a new one, with higher part power, like 20. Is there a better way to do this? I'm doing some crazy tests with SAIO and multiples storage nodes, based in build a new ring with part power 20 and just swap the old files (account/container.ring.gz) with the new ones and let the replicators do their jobs, moving *.db files to their new home partition. Until today these tests worked fine, but I don't know how to do it on a large scale, with some terabytes of data. Just wondering about some ways to do that :) And before/after this change, is there any command in swift that i can audit this entire process, ensuring that cluster data remains the same?

[swift] Multi-policy container
by m.victorello＠luizalabs.com 13 Mar '24

13 Mar '24

Hello, Is there any plan to support multi-policy containers? Why the container's database have a 'storage_policy_index' column for objects? As far as I know the policy index comes from the container (broker.get_info). I don't know that much about changing the policy of a container, i think those are related.

[magnum] ClusterAPI driver out of tree
by Jake Yip 13 Mar '24

13 Mar '24

Hi all, After the previous discussions[1] on the ML, Magnum and StackHPC have decided to create and maintain separate repos[2] for StackHPC's contributed cluster api driver. The repos are currently 1. magnum-capi-helm - driver implementation 2. magnum-capi-helm-charts - helm charts used by driver This will allow the driver to be out of tree, yet still be in governance. StackHPC and Magnum Core team will work together to test the driver in CI. I hope this will please everyone and be a way forward. Regards, Jake [1] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack… [2] https://review.opendev.org/c/openstack/governance/+/910240 [3] https://review.opendev.org/c/openstack/project-config/+/910239 -- Jake Yip Technical Lead, ARDC Nectar Research Cloud
