Flask Web App with Jenkins and Docker

This repository contains a basic Flask web app, a Dockerfile to containerize it, and a Jenkins pipeline to automate building and deployment.

Files in This Repo

• app.py: A minimal Flask app that returns "Hello, Jenkins!" on the home page.
• Dockerfile: Docker configuration to build the app image.
• Jenkinsfile: Jenkins pipeline with two stages:
  • Build: Builds a Docker image from the Dockerfile.
  • Deploy: Runs a container from the image, exposing it on port 5000.

Prerequisites

• Docker: Install Docker Desktop for Windows to build and run containers.
• Jenkins: Set up Jenkins with Docker access.
