Transaction History – Docker Compose Project 🐳

📌 Project Overview

• Multi-container application managed using Docker Compose
• Separate services for application and supporting components (example: database)
• Single command deployment using docker-compose
• Focused on container orchestration rather than application logic

---

🛠️ Technologies Used

• Docker
• Docker Compose
• Dockerfile
• Node.js (application service)
• Database service (if applicable)
• Git & GitHub

🐳 Docker Compose Explanation

The docker-compose.yml file is used to:

• Define multiple services in a single file
• Build images using Dockerfile
• Configure container networking
• Map ports between host and containers
• Start and stop all services together

This reflects real-world DevOps workflows where applications run as multiple containers.

▶️ How to Run the Project (Using Docker Compose)

2️⃣ Build and start services docker-compose up -d

3️⃣ Verify running containers docker ps

4️⃣ Access the application

Open your browser and visit:

http://localhost:PORT (Use the port defined in docker-compose.yml)

⏹️ Stop the services docker-compose down

🎯 Learning Outcomes

Understanding Docker Compose workflow Managing multi-container applications Using Dockerfile with Docker Compose Container networking and port mapping One-command deployment of services

☁️ Cloud & DevOps Relevance

This project simulates real-world scenarios such as: Running application + database containers together Preparing applications for Kubernetes or AWS ECS Managing containerized microservices Using Docker Compose for local development and testing
