Jenkins CI/CD Environment Setup for CartForge Commerce

Business Scenario

At CartForge, with the cloud infrastructure now secured through VPC, subnets, and route tables, the platform was ready for the next major step—automation.

The manager discovered a growing challenge:
Manual deployment processes were slow, repetitive, and increased the risk of errors, making future updates inefficient for the development team.

He assigned the responsibility to the junior DevOps engineer.

After evaluating the workflow, the DevOps engineer proposed the best solution:
Set up a robust Jenkins CI/CD environment to automate build, test, and deployment pipelines for the CartForge Commerce application.

The DevOps engineer then explained the strategy to the team:
By implementing Jenkins automation, CartForge could achieve faster deployments, continuous integration, reduced manual effort, improved delivery consistency, and a scalable DevOps workflow for long-term growth.

Pre-Lab Preparation

In this lab, you will build a basic CI/CD environment for the CartForge application using Jenkins.

You will:

  • Understand how automated pipelines work using a real-world case study

  • Set up a Jenkins server

  • Configure a pipeline for CartForge

  • Execute an automated build

By the end of this lab, you will have a working CI/CD setup that automates basic tasks.

Task 1: Setup Jenkins Server

1

Connect to Your Server

ssh -i key.pem ubuntu@your-ip

Update System

sudo apt update
sudo apt upgrade -y

Install Java

sudo apt install openjdk-21-jdk -y

Verify Java

java -version

Install Jenkins

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee \
/usr/share/keyrings/jenkins-keyring.asc > /dev/null

echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
/etc/apt/sources.list.d/jenkins.list > /dev/null

sudo apt update

sudo apt install jenkins -y

Start Jenkins

sudo systemctl start jenkins
sudo systemctl enable jenkins

Check Status

sudo systemctl status jenkins

2

Open browser:http://your-public-ip:8080

Access Jenkins Dashboard

Get Initial Password

sudo cat /var/lib/jenkins/secrets/initialAdminPassword

Install suggested plusing

And here is the looks

Setup Jenkins

  • Paste password

  • Install suggested plugins

  • Create admin user

And its done!!

3

Configure CartForge CI/CD Environment

Install Required Tools

sudo apt install git -y
sudo apt install nodejs -y
sudo apt install npm -y

Verify Installation

git --version
node -v
npm -v

4

Create Jenkins Job

Steps in Jenkins UI

  1. Click New Item

  2. Enter name: cartforge-pipeline

  3. Select Freestyle Project

Configure Source Code

  • Select Git

  • Enter repository URL of CartForge

Add Build Step

  • Add Execute Shell
  • npm install
  • npm start

5

Execute Automation

Run Job

Click Build Now

Observe Console Output

You will see:

  • Code is fetched from repository

  • Dependencies are installed

  • Build process runs

Validation

Check:

  • Build status is SUCCESS

  • No errors in console output

 

Great job!

  • Transitioned from manual server management to automated deployment workflows using modern DevOps practices.
  • Built a scalable foundation for continuous integration, automated testing, and faster application delivery.
  • Prepared the pipeline for future cloud integration and fully automated production deployments.
