Internal connectivity from agents to Rancher

Hi there,

I’m using the official chart to deploy a 2.5 version of Rancher into a hosted Kube (GKE).
Rancher is accessible via Internet.

However, the infrastructure is designed as private (private endpoints/shared vpc/no internet connectivity wanted between the agents and rancher itself).

So i created an alternate LB with internal ip adressing.

The thing is, given the chart available for the rancher initial deployment, i dont know and cant find any information on how we correctly setup the CATTLE_SERVR env var used by the cluster agents.

These agents are deployed by Rancher itself and i dont know i we can have control of these parameters (maybe hosting ourself the charts with the proper yaml overlays for rancher-agent?)

Any idea?
