Jenkins Pipeline Demo with Java

Overview

This project demonstrates a simple Jenkins CI/CD pipeline using a Java program. The pipeline is implemented with a Jenkinsfile and showcases practical knowledge of Jenkins setup, pipeline creation, and GitHub integration.

The Java program simply prints "Hello World". The project covers:

• Writing a basic Java program.
• Creating a Jenkinsfile for pipeline automation.
• Setting up Jenkins on an AWS EC2 instance.
• Cloning a GitHub repository into Jenkins.
• Building and executing the Jenkins pipeline successfully.

Procedure / Steps Taken

1. Java Program

   • Wrote a simple Java program HelloWorld.java that prints "Hello World".

2. Jenkins Setup

   • Launched an EC2 instance to host Jenkins.
   • Installed Jenkins on the EC2 server.
   • Installed necessary Jenkins plugins (Pipeline, Git, etc.).

3. Pipeline Job

   • Created a Jenkins pipeline job.
   • Connected the job to the GitHub repository containing the Java program and Jenkinsfile.

4. Jenkinsfile

   • Defined stages to:
     1. Clone the GitHub repository.
     2. Build and run the Java program.
   • Used agent any to run the pipeline on any available agent.

5. Build

   • Triggered the pipeline build.
   • All stages executed successfully, demonstrating a working CI/CD pipeline.

Key Learnings

• Hands-on experience with Jenkins pipelines and Jenkinsfile.
• Knowledge of EC2 setup for Jenkins.
• Integration with GitHub repository for automated builds.
• Understanding of pipeline stages, agents, and job configuration.
