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>
