====== Pod ======

A Pod is the **smallest unit in Kubernetes**.

It represents one running instance of your application.

===== What a Pod contains =====
  * One or more containers
  * Shared network (same IP)
  * Shared storage (optional)

---

===== Example =====

A simple web app:


Pod:

nginx container

===== Real-world analogy =====

Pod = "one running app instance"

Like:
  * One Docker container running your service
  * But managed by Kubernetes

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

Pods are temporary:
  * They can be created
  * They can be destroyed
  * They are NOT stable (IP changes)
