Task Manager with Jenkins CI/CD

A simple Task Manager web application built with Flask and Python, featuring a fully automated CI/CD pipeline using Jenkins and Docker.

Note: The main focus of this project is NOT the app itself — it's the DevOps pipeline that automatically builds, tests, and deploys it on every GitHub push.

CI/CD Pipeline

Every push to the main branch triggers the Jenkins pipeline automatically:

GitHub Push
     ↓
Stage 1: Clone      — Pull latest code from GitHub
     ↓
Stage 2: Build      — Build Docker image from Dockerfile
     ↓
Stage 3: Test       — Run pytest test suite (4 tests)
     ↓
Stage 4: Deploy     — Stop old container, start new one on port 5000
