Set Up a CI/CD Pipeline for Web Apps Using Jenkins on Cloud

Automate your build, test, and deployment process using Jenkins running on cloud infrastructure like AWS EC2 or Azure VM to streamline DevOps for web applications.

Why CI/CD Pipelines Matter?

Continuous Integration and Continuous Deployment (CI/CD) pipelines ensure that code changes are automatically tested, built, and deployed — reducing human error and speeding up development cycles. Jenkins is one of the most powerful open-source tools for managing CI/CD pipelines.

Project Objective

Set up Jenkins on a cloud VM to automate your web app's delivery process. Connect to GitHub, run build/test scripts, build Docker images, and deploy to a cloud server, container registry, or Kubernetes cluster.

Core Features to Include

Source Code Integration

Connect your GitHub/GitLab repo with Jenkins using webhooks for automatic build triggers.

Automated Build & Test

Define build/test stages in Jenkinsfile using shell scripts or build tools (npm, Maven, etc).

Docker Image Creation

Use Jenkins to build and push Docker images to Docker Hub or Amazon ECR.

Cloud Deployment

Automatically deploy the app to a cloud VM, Kubernetes cluster, or serverless environment after successful tests.

System Architecture Overview

Jenkins is installed on a cloud VM (e.g., AWS EC2 or Azure VM). A webhook from GitHub triggers Jenkins on code commits. Jenkins pulls the code, runs unit tests, builds the Docker image, and deploys it to the hosting environment or container cluster.

CI Tool: Jenkins (installed on cloud VM)
Source Control: GitHub/GitLab
Build Tools: NPM, Maven, Gradle (based on tech stack)
Deployment: AWS EC2, ECS, EKS, or Azure App Service
Container Registry: Docker Hub / AWS ECR / GitHub Packages

Recommended Tech Stack & Tools

CI/CD Tool

Jenkins (with Blue Ocean UI), Jenkinsfile for pipeline-as-code

Cloud Infrastructure

AWS EC2 / Azure VM for Jenkins host, Docker for containerization

Deployment Target

AWS EC2 / ECS, Azure App Service, or Kubernetes (GKE/EKS/AKS)

Notification & Monitoring

Slack webhook for build notifications, Jenkins Email plugin for reports

Step-by-Step Setup Plan

1. Launch Jenkins on Cloud

Install Jenkins on an AWS EC2 or Azure VM with proper firewall/security group rules.

2. Configure Jenkins with Git

Integrate your GitHub repo using a webhook and Jenkins credentials.

3. Write Jenkinsfile for Pipeline

Define stages for checkout, test, build, Docker push, and deploy in a pipeline script.

4. Set Up Deployment Server

Configure SSH or deployment access to your target server (VM or cluster).

5. Automate & Monitor

Test pipeline execution, add notifications, and enable build history with retention settings.
