Inside Kubernetes Networking
summary
Provides a concrete, executable mental model of Kubernetes networking: a graph of containers, port switches, node switches and links with explicit forwarding information base rules that implement Pod-to-Pod, daemon-to-Pod, ClusterIP anycast, NodePort translation and Ingress proxying. Walks a message step-by-step through localhost delivery, same-node and cross-node forwarding, service IP -> Pod translations and NodePort -> Pod mapping, showing how address/port rewrites and routing choices actually occur in an idealized CNI-agnostic implementation.
