I am installing Rancher on K3S using the below command. If I set hostname to one of the K3S nodes, I can get it installed. However, keeping HA in mind, should the hostname be pointed to an external Layer 4 Loadbalancer forwarding ports 80/443? helm install rancher rancher-latest/rancher \ --namespace cattle-system \ --set hostname=<IP_OF_LINUX_NODE>.sslip.io \ --set replicas=2 \ --set bootstrapPassword=<PASSWORD_FOR_RANCHER_ADMIN>

yes for HA it should, but you’ll need to get actual DNS for that, since you can’t point something at multiple addresses with sslip.io

Thanks @creamy-pencil-82913. Could you please point me to the documentation to use service-lb?

It comes with k3s, you don't have to do anything to use it
