1️⃣ Kubernetes Architecture Overview

Kubernetes is a container orchestration platform that automates deployment, scaling, and management of containerized applications. It follows a master-worker architecture where the Master Node manages and controls the Worker Nodes, which run the application workloads.

2️⃣ Working with Kubernetes

How Kubernetes Works:

• We create a manifest file (YAML/JSON).
• Apply it to the Kubernetes cluster (Master Node).
• The desired state is achieved through the Master.
• Pods (smallest deployable unit) run on Worker Nodes, controlled by the Master.

Role of the Master Node:

• Kubernetes clusters consist of containers running on bare-metal, VMs, or cloud instances.
• One or more nodes are designated as Master Nodes, while others serve as Worker Nodes.
• The Master Node runs Kubernetes control processes, known as the Control Plane, ensuring cluster stability.
• Multi-master configurations provide high availability.
• The Master Node ensures smooth functioning of the cluster through various components.
