Visual guide breaks down Kubernetes control plane and worker nodes
_jaydeepkarale · x · 2026-07-29
A visual explainer breaks down the two halves of a Kubernetes cluster:
- Control plane: API server, scheduler, controller manager, and etcd.
- Worker nodes: pods, container runtime, kubelet, and kube-proxy.
The diagram walks through what each component does: the API server is the entry point, the scheduler assigns Pods to nodes, the controller manager keeps the cluster in the desired state, and etcd stores cluster state. On the worker side, Pods run containers, the runtime manages lifecycle, kubelet enforces Pod specs, and kube-proxy handles networking.
