Ever wish Kubernetes could just understand your app’s needs out of the box?

Well… it actually can — with CRDs (Custom Resource Definitions).

🤔 What Are CRDs?

CRDs are a way to teach Kubernetes new words — letting you define custom objects beyond what’s built-in (Pod, Service, Deployment, etc.).

They’re the magic sauce behind tools like ArgoCD and Kyverno.

✨ Why Use CRDs?

Imagine wanting Kubernetes to manage something like:

  • DatabaseCluster
  • BackupSchedule
  • TaskRunner

With CRDs, you can define these as native-looking resources, so you can:

bash
kubectl get backupSchedules
kubectl apply -f my-database-cluster.yaml
