🚀 CI/CD Pipeline with Jenkins, Docker, and Kubernetes

📌 Project Overview

This project demonstrates a full DevOps workflow by building, containerizing, and deploying a Node.js application using:

• Jenkins for CI/CD automation
• Docker for containerization
• Kubernetes for orchestration
• AWS EC2 as the hosting environment

The pipeline automates:

1. Code build & test
2. Docker image creation
3. Pushing the image to Docker Hub
4. Deploying the app to Kubernetes (currently manual, can be automated later)

🛠 Tech Stack

• Backend: Node.js + Express
• CI/CD: Jenkins
• Containerization: Docker
• Orchestration: Kubernetes (kubectl / k3s / minikube)
• Hosting: AWS EC2 (Ubuntu)
• Registry: Docker Hub

⚙️ Pipeline Workflow

• Developer pushes code to GitHub

• Jenkins pulls the code via webhook

• Jenkins builds the Docker image and tags it

• Docker image is pushed to Docker Hub

• (Manual step) Run kubectl apply -f k8s/ to deploy to Kubernetes cluster

---

📋 Prerequisites

• Before running this project, ensure you have:

• AWS EC2 instance (Ubuntu)

• Docker installed

• Jenkins installed and configured

• Kubernetes cluster (minikube, k3s, or full cluster)

• Docker Hub account

🚀 Setup & Installation

1️⃣ Clone Repository

git clone https://github.com/Aamir017/CI-CD-Pipeline-for-Log-Monitoring.git
cd CI-CD-Pipeline-for-Log-Monitoring

2️⃣ Build & Run Locally

docker build -t log-monitor .
docker run -p 3000:3000 log-monitor

Open http://localhost:3000 in your browser.

3️⃣ Jenkins Setup

• Install required Jenkins plugins:

  • Docker Pipeline

  • Git

  • Kubernetes CLI

• Create a new Pipeline job and link it to your GitHub repo

• Add your Docker Hub credentials in Jenkins
