Hello, could anybody help with the steps to migrate a Rancher Server on RKE2 (Local Cluster) Rancher Ingress resource from ingress-nginx to Traefik? There was previously a pubic SUSE article, "guide for migrating the Rancher Ingress to Traefik in an RKE2 cluster" but it has recently been moved behind login.

Think this guide can help you: https://docs.rke2.io/reference/ingress_migration

Thanks, appreciate the link. This does cover the RKE2 parts but not the implications for Rancher Server Ingress during the process. I've just seen there is a rancher-setup channel, I will post in there too.

What you mean with the Rancher Server Ingress? E.g. just the

Ingress

resource? This doesn't have to be migrated once you replaced the actual controller? Or do you mean moving from Ingress to the GatewayAPI?

No, not moving to GatewayAPI. Helm creates the Rancher

Ingress

resource and I thought I remember reading in the previously public SUSE article that after reconfiguring RKE2 to use traefik ingress controller helm needed to be run to update the

Ingress

resource. Is that not the case? The current Rancher

Ingress

resource doesn't have a ingressClass defined. Does this mean it will use traefik as soon as traefik is the only ingress controller?

That probably depends on how you configure Traefik. But it's probably not more than updating the ingressClass.
