====== apiVersion ======

apiVersion defines **which version of the Kubernetes API you are using**.

---

===== Why it matters =====

Kubernetes evolves over time:
  * Features change
  * APIs are updated
  * Some versions are deprecated

So you must specify the correct version.

---

===== Examples =====

  * Pods → v1
  * Services → v1
  * Deployments → apps/v1
  * Ingress → networking.k8s.io/v1

---

===== Example usage =====


apiVersion: apps/v1


---

===== Key idea =====

apiVersion = "which Kubernetes API understands this object"
