====== metadata ======

metadata contains **information about the Kubernetes object**.

It does NOT define behavior — only identity and labels.

  * name → unique object name
  * namespace → where it belongs
  * labels → tags for selection
  * annotations → extra info

---

===== Example =====


metadata:
name: my-app
labels:
app: web

Service → selects Pods using labels


selector:
app: web


---

metadata = "who is this object?"
