Kubernetes Networking

Networking infrastructure for Kubernetes

Acnodal is the team behind PureLB — the Service LoadBalancer controller for on-prem and bare-metal clusters that works the way Linux already does.

PureLB

A Kubernetes Service LoadBalancer for on-prem and bare-metal clusters that works across both local (same-subnet) and routed (BGP) network topologies — built on the host's standard Linux networking with no overlays or custom data plane.

  • Dual-stack IPv4/IPv6
  • Integrated BGP
  • Multi-subnet local addresses
  • Netbox IPAM
  • CRD-based config
  • Prometheus metrics
  • kubectl plugin

About Acnodal

We build open source networking infrastructure for Kubernetes. Our focus is the boundary where clusters meet the rest of the network — load balancing, BGP, IP address management — using standard Linux primitives rather than parallel data planes.

In addition to PureLB, we previously built EPIC, a multi-tenant, multi-cloud, multi-cluster external API gateway powered by Envoy with Gateway API controllers (source). We also have experience with upstream projects across the cloud-native networking stack including Envoy, GoBGP, Gateway API, and external-dns.

Beyond our open source work, we consult on Kubernetes networking — architecture, BGP design, integration, and troubleshooting — and provide production support, deployment assistance, and custom development for teams running PureLB. Reach us at contact@acnodal.io.
