Re-explain

Kubernetes is an open-source container orchestration platform that automates deployment, scaling, and management of containerized applications. The main components include:
Master Node Components:

  • API Server: Central management component that exposes the Kubernetes API
  • etcd: Distributed key-value store that stores cluster state and configuration
  • Controller Manager: Runs controllers that regulate cluster state
  • Scheduler: Assigns pods to nodes based on resource requirements
    Worker Node Components:
  • kubelet: Agent that communicates with the API server and manages pods
  • kube-proxy: Network proxy that maintains network rules
  • Container Runtime: Software that runs containers (Docker, containerd, CRI-O)
