From User To Contributor: A Quick Guide To Kubectl & Kustomize
summary
Shows how kubectl commands are structured and how kustomize renders overlays into final manifests with concrete patterns, libraries and code links. Explains the CLI runtime plus client-go and Cobra, the constructor/options pattern and the three-phase flow complete/validate/run, how commands pass streams instead of stdio and reuse printers and resource builders, and how kustomize executes generators before transformers with a hardcoded order. Includes real examples (api-resources, annotate, wait), source paths, and embedding commands into other tools.
