Kubernetes Study Portal

TL;DR

Kubernetes is a declarative orchestrator: you tell the API server "I want N replicas of this Pod with these resources", and the control plane (scheduler, controller-manager, etcd) plus per-node agents (kubelet, kube-proxy) drive reality toward that spec. Know the workload primitives — Pods are ephemeral, Deployments own ReplicaSets for rolling updates, Services expose them — and most cluster behaviour stops being mysterious.
