This is Part 3 of the ongoing Kubernetes tutorial series.
Previous articles: Part 1, Part 2.
Kubernetes has revolutionized the way we deploy, scale, and manage containerized applications. To effectively use Kubernetes, it’s crucial to understand its architecture. This article provides more details on the core components of Kubernetes, focusing on Master and Worker Nodes, and the role of etcd.
Master and Worker Nodes
Kubernetes clusters are composed of two main types of nodes: Master Nodes and Worker Nodes. Each type of node has specific components that play vital roles in the cluster’s operation.
Components of the Master Node
The Master Node is the control plane of the Kubernetes cluster. It manages the cluster, making global decisions about the cluster (e.g., scheduling), and detecting and responding to cluster events (e.g., starting up a new pod when a deployment’s replicas field is unsatisfied).
1. API Server
The API Server is the front end of the Kubernetes control plane. It exposes the Kubernetes API, which is used by all components to communicate with each other. It also serves as the entry point for…
