Porter - An Open Source Load Balancer for Bare Metal Kubernetes
summary
Porter is an open source load balancer that implements BGP-based ECMP to announce service routes from a Kubernetes cluster on bare metal, using a built-in BGP server, lightweight agents, and a CRD + controller to watch Services and Endpoints. It allocates from an external IP pool with per-namespace quotas, dynamically programs routers from multiple vendors, and preserves client source IP for auditing. The project is implemented and runs live with zero-downtime updates.
