Explain the architecture of Kubernetes

beginner

Re-explain

Kubernetes follows a master-worker architecture:

Control Plane (Master) Components:

API Server: Entry point for all REST commands; validates and processes requests
etcd: Distributed key-value store that holds cluster state and configuration
Controller Manager: Runs controllers that manage cluster state
Scheduler: Assigns pods to nodes based on resource requirements and constraints

Worker Node Components:

kubelet: Agent that communicates with the control plane and manages containers
kube-proxy: Network proxy that maintains network rules and handles load balancing
Container Runtime: Software responsible for running containers (Docker, containerd, CRI-O)
