Kubernetes Master Class: Creating RKE2 Cluster Templates

Rancher 2.6 introduces a new Cluster-API based provisioning mechanism for RKE2 and K3s clusters. This also brings a completely new cluster templating system, which is based on Helm charts and is much more flexible compared to the old RKE1 cluster templates.
In this master class, you will learn how the Cluster API works, how you can leverage it in Helm Charts, how to do versioning and how to create a nice UI wizard for them.

Is there any plan for updating the documentation with the machine and machnie pools settings?

[@WolframRavenwolf]

I'm really looking forward to RKE2 being supported on vSphere (not experimental anymore, but working out of the box with Rancher)!

[@SJ-eu7em]

Why would you put it on vSphere? Without it you could save a lot of $ without much downside as the HA is managed in k8s layer.

[@WolframRavenwolf]

@@SJ-eu7em We already have a vSphere-based infrastructure, so I'm using what we've got. I'd prefer to use Rancher to deploy downstream clusters through the management interface instead of using Terraform to create and import those clusters manually. As of now, there are bugs that prevent this from working out of the box, so hopefully they get fixed with the next release.

@@WolframRavenwolf did you able to figure out rancher creating downstreame k8s cluster on vsphere infra. I have same setup in our infra. I already installed rancher. But when i create downstreame infra, it fails ssh in docker container, i notice this docker containers keep restarting. not enought help online to figure this out. please let me know if you fix it ?

I really want to love this - but the documentation on this subject is still, 7 months after this aired, so very, very bad.

Awesom presentation with explanations and examples!

[@aliakbarhemmati31]

the templates provided here are not clusterAPI's. Can we use cluster API configs directly with rke2?

[@wollginator]

+ 1 to this, that would be really interesting!

Thanks

[@PuguhRismadi]

Awesome explaination

[@rotemshoshani424]

documentation is still bad, are there any plans to add proper configuration references? It is virtually impossible without second guessing every other option. I'm trying to setup an rke2 on Openstack in a way that will allow users to self-service, what a PITA. Machine configs are a mess on the UI, why not just take the node driver UI from RKE1?

[@prosigam]

i have a porject simmilar to yours. i have an openstack cloud and want to do self service for RKE2 clusters. did you manage to find a good solution ? is it working fine (i mean the templating ?)

How to upgrade cluster use RKE1 to RKE2 ?
