The compute node tries to register with Nova on the controller but can't communicate with it. The problem appears to be at RabbitMQ, which says it can't reach the controller. First things you should check: Unsynchronized clocks and incorrect configuration of name resolution on the compute node. -----Original Message----- From: Asma Naz Shariq <asma.naz@techavenue.biz> Sent: Monday, November 20, 2023 3:50 PM To: openstack-discuss@lists.openstack.org Subject: RE: openstack-discuss -Nova Compute - Error | Urgent Hi Openstack Community, I am deploying Openstack zed release Multinode cluster with 1x Controller and 1x compute and 1x storage.

Hi Folks,
Tell me if I am wrong. CAPI is just kubernetes images to build k8s clusters instead using coreOS and install a bunch of stuff via heat. In documentation all I can see are imported images. Reference doc: https://vexxhost.github.io/magnum-cluster-api/user/getting-started/
Do I need to install anything else to make it work?

Hello guys.
I have successfully implemented Magnum CAPI on my openstack system. My deployment tool for Openstack is Kolla-Ansible. It worked greatly, I am testing with create, delete and resize k8s cluster. It is smooth when compared with Heat Driver. I will make some docs for new users to use it.
Thank you vexxhost.com and contributors for very nice production.
I will keep testing and reporting to help it be much better in the future.

Hi there,
Nope – it is simply a different driver, so if you try to create Fedora CoreOS clusters – it’ll use the old heat driver. Otherwise, it will use the Cluster API if the image is marked as Ubuntu
Thanks!

Hello Mohammed,
I found that
https://vexxhost.github.io/magnum-cluster-api/user/getting-started/# creating
I would like to know that if we use cluster api, does it overwrite heat when deploying new k8s cluster from horizon?

Sounds good, thank you.
We also have a channel on the Kubernetes Slack that is relatively active if you need help — it’s in the README :)
Thanks!

Hi there!
It works out of the box since the goal is to have an API that is compatible so that all the ecosystem tools such as Terraform, Ansible, CLI, Horizon all continue to work just fine!
We’ve even made some quality of life improvements to the Magnum plugin like letting you download KUBECONFIG from it.
Thanks

Hello,
Thank you for your sharing, Could you tell me how we use it with Horizon or we need custom Horizon to use Magnum CAPI.

Hi there.
We deploy this driver in production in our public cloud as well as many private clouds and as part of Atmosphere and we’ve been fully maintaining it on our side here.
Let me know if you have any questions
Thanks
