The Datacenter Network You Wish You Had

This document summarizes a presentation about achieving container networking without overlays by routing container IP addresses directly in the datacenter network. The presentation argues this approach reduces complexity, increases reliability, and avoids vendor lock-in. It then demonstrates routing containers in a spine-leaf fabric topology using Docker, Quagga routing on servers, and dynamic routing protocols. Container IPs are distributed as host routes throughout the network, providing connectivity, isolation, capacity scaling and high availability.
