Inside Linux Namespaces: A Deep Dive into the Kernel Primitives Behind Modern Containers

Namespaces are the unsung kernel feature behind every container runtime. This post walks through the eight namespace types, how they appear in the kernel, and how Docker, Kubernetes, and runc compose them into the isolation boundary you trust in production.
