Kubernetes Deploy

Overview

This project deploys a containerized application on Kubernetes, providing a scalable and reliable runtime environment. It defines how the application runs, exposes it internally and externally, and handles traffic using standard Kubernetes resources.

The focus is on consistent deployment, service exposure, and scaling, using declarative configuration.

Stack

• Kubernetes

• Docker

• kubectl (CLI tool)

• Minikube / Cloud cluster

Architecture

Deployment → Pods → Service → External Access

Deployment Configuration

apiVersion: apps/v1
kind: Deployment
metadata:
  name: app-deployment
spec:
  replicas: 2
  selector:
    matchLabels:
      app: app
  template:
    metadata:
      labels:
        app: app
    spec:
      containers:
        - name: app
          image: app:latest
          ports:
            - containerPort: 3000

Service Configuration

apiVersion: v1
kind: Service
metadata:
  name: app-service
spec:
  type: NodePort
  selector:
    app: app
  ports:
    - port: 80
      targetPort: 3000
      nodePort: 30007

Commands

kubectl apply -f deployment.yaml
kubectl apply -f service.yaml

kubectl get pods
kubectl get services

Scaling

kubectl scale deployment app-deployment --replicas=4

Result

• Application runs in multiple pods
  

• Traffic is distributed across instances
  

• Service exposes the application externally
  

• Scaling handled with a single command
  

Key Points

• Declarative deployment using YAML
  

• Automatic pod management
  

• Built-in scaling and load balancing
  

• Consistent runtime environment
  

Final Note

This project demonstrates how applications can be deployed and managed at scale using Kubernetes.

It ensures that applications are resilient, scalable, and easy to manage in production environments.
