[openstack][largescale-sig] Openstack multi region deployment
by Karl Kloppenborg 24 Jul '23

24 Jul '23

Hi Nguy, We’ve deployed a large multi-region openstack deployment. As a rule of thumb we’ve got a “keystone” region which is as best we can highly available and very redundant. We then have all other regions talk back to this region, we just usually call it “keystone” or “core” and it’s hidden from the UI from users. We then just run a large well kept Galara cluster to support it. --Karl.

I plan to set up 2 regions which use centralize galera cluster(3 nodes). and one standby edge galera cluster(3 nodes) When region 1 is node available, I will map region 2 to use standby edge galera cluster. I hope you give me some experience and advice with multi regions. Thank you very much.

Ussuri: how to delete lbaas loadbalancer left over?
by Michel Jouvin 24 Jul '23

24 Jul '23

Hi, We had a few Magnum (K8s) clusters created a couple of years ago (with Rocky and Stein versions) and forgotten. We started to delete them this spring when we where running Train Neutron service. Basically we managed to do this with the following sequence: - openstack coe cluster delete xxx and waiting for DELETE_FAILED - Use openstack coe cluster show / openstack stack resource list -n2 to identify the neutron entry causing the error and pick the corresponding resource ID - Find the ports associated with the router with openstack port list --router previously_found_id - Use the port subnet to find the port corresponding lbaas load balancer ID, use the neutron CLI to delete the load balancer (deleting one by one all the dependencies preventing the load balancer removal) - Rerun openstack coe cluster delete For some reasons, we didn't cleanup all the abandoned clusters and upgraded Neutron to Ussuri. Unfortunately, since then our previous process is no longer working as it seems that the Neutron server doesn't know anymore anything about the LBAAS load balancers (and "neutron lbaas-loadbalancer list" returns nothing). In the neutron server, any attempt to delete the subnet attached to the load balancer (or to list them with Neutron CLI) results in the following errors in Neutron server.log : ------ 2023-07-07 16:27:31.139 14962 WARNING neutron.pecan_wsgi.controllers.root [req-71e712fc-d8a7-4815-90b3-b406c10e0caa a2b4a88cfee0c18702fe89ccb07ae875de3f34f3f1bb43e505fd83aebcfc094c 245bc968c1b7465dac1b93a30bf67ba9 - 1367c9a4d5da4b229c35789c271dc7aa 1367c9a4d5da4b229c35789c271dc7aa] No controller found for: lbaas - returning response code 404: pecan.routing.PecanNotFound 2023-07-07 16:27:31.140 14962 INFO neutron.pecan_wsgi.hooks.translation [req-71e712fc-d8a7-4815-90b3-b406c10e0caa a2b4a88cfee0c18702fe89ccb07ae875de3f34f3f1bb43e505fd83aebcfc094c 245bc968c1b7465dac1b93a30bf67ba9 - 1367c9a4d5da4b229c35789c271dc7aa 1367c9a4d5da4b229c35789c271dc7aa] GET failed (client error): The resource could not be found. 2023-07-07 16:27:31.141 14962 INFO neutron.wsgi [req-71e712fc-d8a7-4815-90b3-b406c10e0caa a2b4a88cfee0c18702fe89ccb07ae875de3f34f3f1bb43e505fd83aebcfc094c 245bc968c1b7465dac1b93a30bf67ba9 - 1367c9a4d5da4b229c35789c271dc7aa 1367c9a4d5da4b229c35789c271dc7aa] 157.136.249.153 "GET /v2.0/lbaas/loadbalancers?name=kube_service_964f7e76-d2d5-4126-ab11-cd689f6dd9f9_runnerdeploy-wm9sm-5h52l_hello-node-x-default-x-runnerdeploy-wm9sm-5h52l HTTP/1.1" status: 404 len: 304 time: 0.0052643 ------ Any suggestion to workaround this problem and be able to successfully delete our old Magnum clusters?

by Danish Khan 22 Jul '23

Dear Team, I am trying to deploy openstack-ansible wallaby but it is getting failed with error: service user token configuration is required for all Nova services. For more details see the following: https://docs.openstack.org/latest/nova/admin/configuration/service-user-tok… But the mentioned webpage is not available. This is fixed in yoga but wallay is still failing. I tried to copy few variables from Yoga but that is working for me. Can someone please help me on this ? where I need to make some changes to deploy openstack-ansible wallaby? Thanks in advance :) Regards, Danish

Re: [all] [oslo.messaging] Interest in collaboration on a NATS driver

Hello Kai, Great to hear that you’re interested! I’m currently just testing this as a POC directly in devstack so there is real-world testing (not should it yet I think, needs more development first).

Although I'm working with OpenStack for my employer at the moment, I'd do this in my spare time as I'm not sure that I can convince him to add another staging system with a full OpenStack installation just for developing a RabbitMQ replacement. That's not on our agenda as we are mostly users and not developers of OpenStack. > > As I'm pretty new to the messaging topic and had just heard of NATS and your idea, I'll first would have to dive into NATS and then I would take a closer look at your code and maybe try to create some documentation or tests.

Hi Everyone, OpenInfra Live is looking for ideas and participants to join a panel to discuss those topics. That being said… do you have a topic in mind that you would like to see on OpenInfra Live? We want to hear from you! Some ideas can include: Data Sovereignty Multi-Region Deployment Kolla-Ansible AI/ML And many more! If you would like to participate or have an idea, you can contact me via email (kristin(a)openinfra.dev) or reply here, and we can work on getting something started. If you would rather write a Superuser article, feel free to email me an abstract and we can go from there. I look forward to hearing everyone’s ideas! Thanks, Kristin Barrientos Marketing Coordinator OpenInfra Foundation
