Extending K8s- Introducing Custom Resources, Controllers, Operators & Schedulers
summary
Demonstrates adding an nginxoperator CRD and running a small Go controller that maps the custom objects onto a Deployment to actually create pods; the CRD alone produces no pods until the controller is running, and deleting a pod causes the controller to recreate it, proving the event‑driven reconcile loop works. Covers CRDs as API endpoints, controllers as watchers/reconcilers, operators for full lifecycle automation, and when a custom scheduler is needed for specialized placement.
