NGINX Deployment on Kubernetes with NodePort Service using Minikube

This project demonstrates how to deploy an NGINX web server on a Kubernetes cluster using a Deployment and expose it using a NodePort Service.

Quick Overview

This guide walks through the steps of deploying NGINX in Kubernetes and exposing it via a NodePort service using Minikube.

By the end, you’ll have an externally accessible NGINX web server running in your Kubernetes cluster.

---

Prerequisites

• Minikube installed on your machine.
• kubectl (Kubernetes CLI) installed.
• Basic understanding of Kubernetes concepts. If you're new to Kubernetes, check out my notes on Kubernetes Overview.

NGINX Deployment and Service Configuration

The following YAML configuration defines an NGINX deployment and a NodePort service that makes it accessible externally.

nginx-deployment.yml File

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        resources:
          limits:
            memory: "512Mi"
            cpu: "500m"
        ports:
        - containerPort: 80

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

Commands to Deploy and Expose NGINX on Kubernetes using Minikube

To deploy and expose NGINX using a NodePort Service with Minikube, I ran the following commands:

1. Create the NGINX Deployment and Service: kubectl apply -f nginx-deployment.yml

2. Verify Deployment and Service kubectl get deployments kubectl get services

3. Access the NGINX Web Server using Minikube:

Get the URL of the service exposed by Minikube:

minikube service nginx-service

This will output the URL where the NGINX service is available:
