Porter - An Open Source Load Balancer for Bare Metal Kubernetes
summary
Porter is an open source load balancer for bare‑metal Kubernetes that implements a local BGP server plus lightweight node agents and a k8s controller to advertise service routes and manage IPs. It uses BGP-based ECMP to create many equal-cost paths (demo cites up to 16) and preserves client source IPs instead of using nodePort NAT. External addresses come from an external IP pool with dynamic assignment and per-namespace quotas; services publish routes in seconds and updates are zero‑downtime.
