====== API Server ======

The API Server is the **entry point of Kubernetes**.

---

===== What it does =====

  * Accepts kubectl commands
  * Validates requests
  * Updates cluster state
  * Communicates with etcd (database)

---

===== Example =====

When you run:


kubectl apply -f deployment.yaml


Flow:
  * kubectl → API Server → Control Plane → cluster update

---

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

API Server = "front door of Kubernetes"
Everything goes through it.
