A look inside: How Kubernetes Architecture Actually Works
Every Kubernetes interview question, no matter how it's phrased, is secretly testing whether you understand this diagram. Memorize what each piece does and "why" questions become easy.
Interview gold: When asked "what happens when you run kubectl apply?" walk through this exact chain: kubectl → API Server (validates + writes to etcd) → Scheduler (assigns node) → kubelet (starts container) → kube-proxy (updates routing).
That chain, in order, is what separates "knows kubectl" from "understands Kubernetes."
