Welcome to the guide on using MetalLB with Kairos and K3s on a bare metal host! In this tutorial, we’ll walk through the steps of setting up a Kairos node on your local network using the 192.168.1.10-192.168.1.20 IP range, with MetalLB and K3s. But first, let’s talk a little bit about what MetalLB and K3s are. MetalLB is a load balancer implementation for bare metal Kubernetes clusters that uses standard routing protocols.
