Hi everyone. I have a question regarding k8s cluster set up on kubernetes. I am setting up a cluster for production that will be having 3 master and 7 worker nodes. These nodes are on-prem. My question is whether rancher automatically creates a LB for the master nodes to divert traffic across multiple master nodes? Secondly, which approach is better for a production base cluster - Having etcd and controlplane on the same node or having separate nodes for etcd and control plane?
