Kubernetes Platform Engineering
Building and Operating Kubernetes as an Internal Developer Platform
Goal: Learn how to design, build, secure, and operate Kubernetes as a multi-tenant platform for engineering organizations. Unlike a Kubernetes administration book (CKA/CKAD/CKS), this book focuses on platform architecture, platform capabilities, developer self-service, and large-scale operations. It assumes foundational Kubernetes knowledge — see Kubernetes for CKA/CKAD/CKS-level fundamentals.
If this were a book, this page is the table of contents. Each Part below is a chapter; each chapter links out to the concepts, designs, and platform notes that already exist elsewhere in this wiki instead of duplicating them. Unwritten chapters are listed as Planned rows, not empty files.
Parts
00 — Kubernetes as a Platform
Why platform teams build on Kubernetes instead of administering it directly, the platform-versus-infrastructure distinction, and the maturity stages a Kubernetes platform moves through. Assumes CKA/CKAD/CKS-level Kubernetes knowledge — see Kubernetes for those fundamentals.

Platform-wide security posture — admission control, policy as code, supply-chain integrity, and runtime detection — enforced centrally rather than left to individual teams.
