About this edition#
This edition is maintained by Martin Keller. The text is published under the Apache License 2.0, the same licence the original book carries (full text). Changes made in this edition: broken chapter links repaired (Helm Part 2 now shows its chapter), lost images re-sourced or removed, command placeholders such as <name of the pod> that had disappeared from the page restored, incomplete commands corrected against the Kubernetes reference (for example the deployment name that kubectl create deployment requires), and new chapters added over time.
In October 2026 these chapters were rewritten from scratch for Kubernetes 1.37 by the maintainer of this edition. They keep the topic and the address of the original chapter, and the original author's video links where there were any; the text, examples and commands are new and were checked against the official documentation: Replica Set, Namespaces, ConfigMaps, K3s and K3sup, Kustomize, Crossplane, k9s, GitOps and Argo, Kubernetes Operators and CrashLoopBackOff. Two chapters are new to this edition: ImagePullBackOff and OOMKilled. The Terraform chapter's AKS authentication example was corrected (kubelogin get-token).
