====== Worker Nodes ======

Worker Nodes are the machines that **run your applications**.

---

===== What runs on a node =====
  * Pods (your applications)
  * kubelet
  * container runtime (Docker/containerd)
  * kube-proxy

---

===== Example =====


Node 1 → nginx Pod
Node 2 → api Pod
Node 3 → database Pod


---

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

Worker Nodes = execution layer
They only run what Control Plane assigns.
