Hi eveyone, I have an upstream Rancher cluster configured with a single domain (e.g., rancher.com) and a downstream cluster (cluster01) where all subdomains (*.rancher.com) are routed to the LoadBalancer on cluster01. I am planning to create a second downstream cluster under the same upstream Rancher. I’m looking for documentation or guidance on setting up this second cluster so that services and load balancing work correctly. Specifically: Do I need to create separate domains for each downstream cluster? How can I configure routing so that user URLs reach the correct cluster? For example: foo.cluster01.rancher.com → cluster01 foo.cluster02.rancher.com → cluster02 I am new to Rancher and Kubernetes, so I apologize for any gaps in my knowledge. I am happy to provide any additional information if needed — just let me know what would be helpful. Thank you!

If I understand correctly, a single LB in front of your upstream Rancher cluster is also balancing the traffic for the downstream cluster01 cluster as well? If that's correct, how is your ingress configured for cluster01? That'd be a place to start.
