Docker + Nginx Web Application

A simple containerized web application using Docker and Nginx web server.

🚀 Technologies Used

• Docker: Container platform for packaging applications
• Nginx: High-performance web server
• HTML/CSS: Frontend design

📋 Prerequisites

• Docker Desktop installed on your system
• Basic knowledge of command line

🛠️ Setup Instructions

1. Build the Docker Image

docker build -t nginx-web-app .

2. Run the Container

Option A: Using Docker command

docker run -d -p 8080:80 --name my-nginx-app nginx-web-app

Option B: Using Docker Compose (Recommended)

docker-compose up -d

3. Access the Application

Open your browser and go to:

http://localhost:8080

🔧 Useful Commands

View running containers

docker ps

View container logs

docker logs nginx-web-app

Stop the container

docker stop nginx-web-app

Remove the container

docker rm nginx-web-app

Stop using Docker Compose

docker-compose down
