# Purpose

Core networking service connecting nodes and pods together. Provides a metal LoadBalancer service.

# Notes

One of the most important apps in cluster. Any updates need special care to ensure success.

Long term goals include migrating the Ingress/Gateway from [Traefik](https://docs.alexlebens.dev/applications/traefik/) to Cilium and using BGP for connecting to the network devices. I've tried this a few times, but networking isn't my strong suit.
