11/30/2022, 7:58 AMIf you have only two servers and one goes down, you can't add a 3rd because the entire cluster will be down as you have no quorum. You should never have an odd number of servers for any significant period of time.

11/30/2022, 9:41 PMThanks @creamy-pencil-82913! In a multi master setup, how would traefik and ingresses work? Does that mean I have to scale up traefik to be deployed in all master nodes?

11/30/2022, 9:53 PMthat depends entirely on how you want to access it. by default it uses ServiceLB for a LoadBalancer service that is accessible through all the nodes, but there’s only a single replica.

11/30/2022, 9:53 PMYou’re welcome to change that though
