Don't use a loadbalancer for etcd, just tell each kube-apiserver about all 3. Use DNS names if you don't want to update all apiservers whenever you swap out an etcd, but that's optional.
For the apiserver itself, the simplest way would be to just put all 3 behind a single DNS name. Otherwise, use any loadbalancer that is available to you, it doesn't really matter, as long as it accepts long-lived connections. I think session affinity is not required, but if you get lots of messages about issues watching from specific versions try that. If you have only one node, what is the benefit of a high availability master? The cluster will keep happily running if a single master is temporarily unavailable, but whenever the single node goes away the applications will be effectively down. /MR On Wed, Oct 25, 2017 at 11:31 AM <sureshelavazha...@gmail.com> wrote: > I am trying to setup a High Availability kubernetes cluster ( 2 masters > and 1 node) in bare metal environment, I need to setup a LB exactly look > like below > > _____ Master1 Port 8080 > | > Load Balancer Port 8080 -- ---- Master2 Port 8080 > | > ----- Master3 Port 8080 > > _____ Master1 Port 2379 > | > Load Balancer Port 2379 -- ---- Master2 Port 2379 > | > ----- Master3 Port 2379 > > can anyone suggest a best way to go? > > -- > You received this message because you are subscribed to the Google Groups > "Kubernetes user discussion and Q&A" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to kubernetes-users+unsubscr...@googlegroups.com. > To post to this group, send email to kubernetes-users@googlegroups.com. > Visit this group at https://groups.google.com/group/kubernetes-users. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Kubernetes user discussion and Q&A" group.
