Container Networking Deep Dive: From Network Namespaces to Kubernetes
Container Networking Deep Dive: From Network Namespaces to Kubernetes Note: This guide is based on the Linux kernel networking documentation, Docker networking documentation (v24+), Kubernetes networking model documentation (v1.28+), and CNI specification v1.0. All examples use documented networking primitives and follow production container networking patterns. Container networking is fundamental to modern cloud-native applications. Understanding how packets flow from pod to pod, how services load-balance traffic, and how network policies enforce security requires knowledge of Linux networking primitives, Container Network Interface (CNI) plugins, and Kubernetes networking abstractions. ...
