Kubernetes is an open‑source system for automating the deployment, scaling, and management of containerized applications. It works by grouping containers into logical units and running them across a cluster of machines, ensuring applications stay available, scalable, and resilient. Kubernetes works by running your containerized applications across a cluster of machines and constantly making sure the system matches the desired state you define. You tell Kubernetes what you want—like “run three copies of this app”—and it schedules Pods (groups of containers) onto worker nodes, monitors their health, restarts them if they fail, balances traffic with Services, and scales them up or down automatically. It’s essentially an automated control system that keeps your apps running reliably and consistently.
