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’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.
