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. There is a RKE2 guide, but it doesn't cover any Rancher Server specifics. https://docs.rke2.io/reference/ingress_migration

That doc seems really straight forward. What part are you stuck on?

Thanks for your replies. We're on Rancher (Server) 2.14.1 currently, there isn't support for RKE2 1.36 yet and since ingress-nginx is already EOL, was expecting to do this on 1.35. The Rancher Ingress resource is created and managed by Helm (rancher-stable/rancher chart). From memory the guide that was previously public included steps to run helm upgrade in order to migrate the ingress resource. I have previously migrated Ingress resources in downstream clusters by updating ingressClassName to traefik but not with the Rancher local cluster where there is a risk of losing access to the Rancher WebUI and disconnecting all the downstream clusters. I do expect this can be recovered with kubectl modifications but I thought there was Rancher specific steps.

Yeah for the local cluster, I think you're just going to want to follow the doc you originally posted.

Thanks, I've successfully migrated the local cluster hosting Rancher to Traefik in a test environment with the following additional helm --set for Rancher:

helm upgrade rancher rancher-stable/rancher \

--set ingress.ingressClassName=traefik

# other --set values
