FYI, this can just be any Kubernetes cluster that you can stand up on any node using `kind` or any other way of getting a cluster up.

Hello.

you should miss

 

We setup a k8s cluster to manage workload clusters which were created by Magnum.

We need get /root/.kube/config from cluster management.

Copy /root/.kube/config from "cluster management" to /var/lib/magnum/.kube/config

Hello guys.

 

This is a doc which is about how to make Magnum CAPI to work with Openstack deployed by Kolla Ansible..

 

 

Feel free to ask. If I can help, I will.

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!

I would like to know that if we use cluster api, does it overwrite heat when deploying new k8s cluster from horizon?

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

Mohammed

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
