Kustomize

This course teaches deploying and customizing Kubernetes resources using Kustomize, covering core features, CI/CD integration, and a capstone project.

Welcome to the Kustomize course! I’m Sanjeev Thiyagarajan, and I’ll guide you through deploying and customizing Kubernetes resources across multiple environments. By the end of this course, you’ll master Kustomize’s core features, integrate it into CI/CD pipelines, and complete a capstone project.

What You’ll Learn

Module Description
Why Kustomize Was Created Understand the challenges in Kubernetes manifests and how Kustomize simplifies customization
Installing Kustomize Install Kustomize locally and configure prerequisites
Defining kustomization.yaml Learn the syntax, reference resources, and organize overlays
Basic Resource Example Create a simple Deployment and Service with Kustomize
Advanced Features Explore transformers, patches, components, generators (ConfigMaps & Secrets)
CLI Subcommands Use kustomize edit, kustomize set, and other subcommands in CI/CD
Hands-On Labs Practice after each lecture with interactive challenges
Final Project Apply all features in a capstone deployment
Community Support Join our Slack channel for Q\&A and peer assistance

Note

Kustomize is now built into kubectl (v1.14+). You can run kubectl kustomize instead of installing a separate binary.

What’s Next?

Now that you know the course structure, we’ll dive into Kustomize’s core features:

  1. Transformers & Patches – Modify fields without touching original YAML.
  2. Overlays & Components – Compose reusable customization layers.
  3. Generators – Automate ConfigMap and Secret creation.
  4. CLI Workflow – Leverage kustomize build, edit, set, and apply.

Ready to customize your first Kubernetes manifest? Let’s jump in!
