What is Kubernetes?
⚡
Quick Answer
Kubernetes is an open-source container orchestration platform that automates deploying, scaling, healing, and networking containerized applications across a cluster of machines.
Detailed Answer
You declare desired state (Deployments, Services, etc.) and Kubernetes controllers continuously reconcile the actual state to match — rescheduling failed pods, scaling on demand, and rolling out updates. It abstracts the fleet of nodes into one API-driven platform.

Interview Tip
Center your answer on declarative desired state + reconciliation — that control-loop idea is the heart of Kubernetes.
