What is kustomize-zero-to-hero?

Kustomize-zero-to-hero is a hands-on tutorial repo that teaches you how to use Kustomize, a tool for managing Kubernetes configurations. Instead of editing configuration files directly every time you need a change, Kustomize lets you layer small adjustments on top of a base setup. The repo walks you through this concept step by step with simple, practical examples. The tutorial is organized into folders that build on each other. You start with the basics of what Kustomize is and how it works, then move on to patches (making specific changes to existing files), configmaps and secrets (working with configuration data), and generators (creating configs automatically). The final section covers real-world examples so you can see how everything fits together in actual projects. Each folder has its own README with explanations and examples you can try yourself. This repo is aimed at people who already have a basic understanding of Kubernetes concepts like pods and deployments, but want to learn how to manage their configurations more cleanly. If you are a developer or ops person who maintains different versions of the same application across environments like development, staging, and production, this tutorial shows you how to keep one shared base and apply only the differences each environment needs. The project is straightforward in scope. It is a learning resource tied to a YouTube tutorial by Abhishek Veeramalla, not a tool or library you install. You need kubectl installed on your computer and a text editor to follow along. The README does not go into detail on advanced use cases or edge cases, sticking instead to a clear beginner-to-intermediate progression.
