METALLB
Bare-metal load balancer for Kubernetes Services
Apache-2.0
ABOUT
LoadBalancer Services stay pending on bare metal because there is no cloud LB controller. MetalLB assigns IPs from a pool and advertises them with BGP or ARP so on-prem GPU clusters can expose inference, embedding, and agent APIs the same way they would on AWS or GCP.
INTEGRATION GUIDE
1. Expose an LLM inference Service with a LoadBalancer IP on a homelab cluster
2. Announce GPU-node Services over BGP into the datacenter fabric
3. Give on-prem vector DB and feature-store APIs stable external IPs
4. Replace a manual HAProxy VIP with MetalLB for Kubernetes Services
