KubeBuilder is different from standard Go in these ways:

1. Uses Kubernetes Concepts

• Instead of a simple main.go, it structures code around Custom Resources (CRDs) and Controllers.
• You don’t write normal functions; you implement reconcilers that react to Kubernetes events.

2. Uses controller-runtime (Not Standard Go)

• KubeBuilder is built on controller-runtime, which provides:
  • Client → Talks to the Kubernetes API
  • Reconciler → Watches resources (like event-driven programming)
  • Manager → Manages controllers

3. More Boilerplate & Scaffolding

• Standard Go: You write only the logic you need.
• KubeBuilder: Generates a lot of YAML, scaffolding, and extra files for RBAC, CRDs, and deployment.

TL;DR

✅ Standard Go → Simple apps (web servers, CLI tools)

✅ KubeBuilder → Kubernetes-native apps (operators, controllers)
