Hello , I am using rancher for high availability k8s setup. I am having 3 master and 2 worker node. I want to know how traffic os flowing for apiserver when i am sending it using kubectl? I know first ot will go to rancher as my kubeconfig is having rancher url but i want to know what happens after rancher? Will it go round robin or how is it works? How can i test it or find out? Any suggestions ?
