Lightning Talk: Hacking Kubernetes Networking to Create Telco Solutions
Lightningat Cloud Native Telco Day Europe 2023 · on Tuesday, 2023-04-18· at 09:25· Hall 7, Room A | Ground Floor | Europe Complex·
summary
Kubernetes defaults break telco needs so kube-vip and BGP (using GoBGP) are used to advertise service IPs into physical routers, replacing brittle NodePort setups; stable egress is solved by a single load‑balancer IP or a dedicated gateway pod that preserves a fixed source address for firewalls; kernel tooling shifts from iptables→nftables to eBPF for better performance and control; several hacked solutions work in production but require careful integration with netfilter and operator automation.
