The HA installation guide says:
"The Rancher management server can only be run on an RKE-managed Kubernetes cluster. "
Is this still true given the high speed of development on K3S?
Is it possible to use HA Rancher on top of a K3S cluster? Given the much-lower hw requirements of K3S, it would lower the running costs of Rancher instances for enthusiasts and smaller companies like me.
I assume, that on Hetzner, a 3-node CX11 cluster (1 vCPU, 2GB RAM, 20GB SSD) would be enough for running a HA Rancher and that would cost only 7,5 EUR/mo.
Given the fact that Rancher is a non-workload-bearing component, it would be nice to have its cost lowered to more palatable levels.
