In a 9 node cluster, one master (etcd+controlplane) and 8 worker nodes. No need of any load balancer I believe.
But what if I have 3 master nodes and 6 worker nodes. Does rancher manages load balancing on it's own? Or specifically we need to deploy load balancing for this?
I've deployed rancher using docker in a VM and from rancher UI I've provisioned Kubernetes cluster
@eager-refrigerator-66976 Will you be able to comment on this.
I believe kube vip can help on load balancing part

what kind of loadbalancing you mean? the workloads?
it doesn’t matter how many workers do you have, as it is just capacity for your cluster

Mainly I'm looking for load balancing option
If we have 3 master nodes
If I've one master, then by default worker nodes will connect to master. In case of 3 master, then there should be load balancing.

if you have multiple masters you should not need any extra LB in front

In On Prem k8s Perspective: Actually we need a load balancer if we have multiple master nodes. The reason is the worker nodes will connect to master nodes, what if master-1 is down and worker nodes are connecting to master-1. How worker nodes will come to know master-1 is down and how it will try to connect to master-2.
In order to achieve this, we need load balancer.
Worker nodes ——>load balancer(kind of kube-vip) ——> Master Nodes
I'm looking for relevant docs
As I've deployed cluster using Rancher UI and need load balancing solution
