There are two tutorials available, showcasing different facets of MetalLB.
The BGP on Minikube tutorial sets up MetalLB in a Minikube sandbox, and showcases BGP load-balancing in a simulated environment. If you don’t have a bare metal cluster to test on yet, or if you want to explore MetalLB’s BGP functionality, this is the tutorial for you.
The Layer 2 tutorial demonstrates setting up layer 2 mode. For this tutorial you will need to bring your own bare metal cluster, unfortunately we don’t yet have a Minikube-friendly demonstration for layer 2 mode.
