What components are included in a Kubernetes cluster?

A Kubernetes cluster consists of two main types of components:

1. Master Nodes (Control Plane):

   • API Server — accepts and processes REST requests from users and components.
   • Scheduler — distributes pods across worker nodes based on resources and requirements.
   • Controller Manager — monitors the cluster's state and manages controllers (e.g., maintaining the desired number of replicas).
   • etcd — a distributed configuration and state storage for the cluster.

2. Worker Nodes:

   • Kubelet — an agent that runs and manages containers on the node.
   • Kube-proxy — provides network interaction and load balancing.
   • Container runtime (e.g., Docker, containerd) — runs containers.

These components together provide management, orchestration, and deployment of containerized applications within the cluster.
