====== Scheduler ======

The Scheduler decides **which node runs a pod**.

---

===== How it works =====

When a new pod is created:

  1. Scheduler sees the pod request
  2. Checks all available nodes
  3. Evaluates CPU, memory, constraints
  4. Picks the best node
  5. Assigns the pod

---

===== Example =====

You create a pod:


nginx pod (needs 200m CPU)


Nodes:


Node A → low CPU
Node B → high CPU (selected)


---

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

Scheduler = "decision maker"
It only decides placement, not execution.
