📝 Overview

Docker-Compose-Multiservice-App is a robust, scalable, and modular web application stack designed for rapid development and deployment. It leverages Docker Compose to orchestrate multiple essential services for enterprise-grade Java web applications.

---

✨ Features

• Modular Architecture: Each service runs in its own container for easy management and scaling.
• Data Persistence: Volumes ensure important data is retained across container restarts.
• Network Isolation: All services communicate over a dedicated Docker network.
• Production-Ready: Easily extend or customize for your needs.
• DevOps Focus: Built for CI/CD, automation, and modern infrastructure practices.
