# Dockerized Node.js Project with Nginx Load Balancing

This project demonstrates how to Dockerize a Node.js application and set up Nginx as a load balancer to distribute traffic among multiple Node.js containers.

## Prerequisites

Make sure you have Docker installed on your machine. You can download and install Docker from [Docker's official website](https://www.docker.com/get-started).

## Project Structure

- **app.js**: Node.js application file.

- **Dockerfile**: Dockerfile for building the Node.js application image.

- **nginx.conf**: Custom Nginx configuration file for load balancing.

## Setup Instructions

### Step 1: Create Docker Network

Create a Docker network named `internal` to allow communication between containers:

```bash

docker network create internal

docker build -t my-node-app .

docker run -d --name node-app --network internal -p 4000:4000 my-node-app

docker run -d --name node-app2 --network internal -p 4001:4000 my-node-app

# Add more instances as needed, adjusting ports accordingly

docker run -d --name nginx --network internal -p 80:80 nginx:latest

docker cp ./nginx.conf nginx:/etc/nginx/conf.d/default.conf

docker restart nginx
