🚀 DevOps Task Manager – Docker + Prometheus + Grafana

A complete DevOps monitoring project built using Docker, FastAPI, Postgres, Prometheus, and Grafana.

This project demonstrates containerized application deployment with real-time monitoring and observability.

---

📌 Project Overview

This project includes:

• 🐳 Dockerized FastAPI application
• 🐘 Postgres database container
• 📊 Prometheus for metrics collection
• 📈 Grafana for visualization
• 📡 API performance monitoring
• 💻 System resource monitoring (CPU, Memory, Disk)

---

🏗️ Architecture

User → FastAPI App → Postgres
