Kubernetes Architecture

Summary

A control plane (API server, scheduler, controller manager, etcd) manages a cluster of worker nodes running your containerized workloads — understanding this split clarifies almost everything else about Kubernetes.

• 1Diagram the control plane and worker node components and what each does.
• 2Learn the role of etcd as the cluster's source of truth (a key-value store of all cluster state).
• 3Set up a local single-node cluster (minikube or kind) to explore this hands-on.
