Load Balanced Services on Bare Metal with MetalLB
summary
MetalLB is a LoadBalancer implementation for bare‑metal Kubernetes that allocates IP pools and runs a controller plus per‑node speaker processes to expose services. It supports two service modes—L2 (one node answers ARP) and BGP (routers can split traffic across nodes)—and recent additions include integration with FRR, BFD, dual‑stack support, and an operator; it runs on Raspberry Pi clusters and in production.
