How Kubernetes Operators Work: Building a Controller From Scratch

by Shiva Swaroop N K

Build a Kubernetes operator for a small Pet API, first as a 15-line bash loop and then as a Go controller with controller-runtime. Every Pet gets a Pod to live in, gets hungry as time passes, and runs away if nobody feeds it. Along the way, you'll see how the reconcile loop works.

How Kubernetes CRDs Work: Designing a Validated API From Scratch

by Shiva Swaroop N K
