Hi All,

Hope the session went well and you guys were able to understand the basics of Jenkins.

As a hands-on exercise, please complete the following task to solidify your understanding of Jenkins integration with GitHub and setting up pipelines using different scripting languages.

🔧 Assignment Task

Objective:

Create a new Jenkins job (Freestyle or Pipeline) that connects to a GitHub project, triggers a build using a webhook on every commit, and runs a scripted pipeline using a language of your choice.

📌 Instructions:

1. GitHub Project Setup

   • Create a simple GitHub repository with a basic application/script using any one of the following languages:

     • Shell script (bash)

     • Python

     • Node.js

     • Java (Maven or Gradle)

     • Go

2. Add a Sample Script/File

   • Include a basic script such as:

     • A Python script that prints "Hello from Jenkins!"

     • A Shell script that lists directory contents

     • A simple Node.js/Java/Go program with a basic function

3. Create Jenkins Job

   • Create a new item in Jenkins (Freestyle or Pipeline).

   • Connect it to your GitHub repository using Git.

   • Enable webhook-based triggering by:

     • Adding the GitHub webhook to your repo ( http://<your_jenkins_url>/github-webhook/ )

     • Configuring Jenkins to trigger build on GitHub push

4. Pipeline Script

   • Write a Jenkinsfile (for Pipeline jobs) or use “Execute shell” (for Freestyle) to run your script.

   • Example (for Python):

     pipeline {
     agent any
     stages {
     stage('Clone Repo') {
     steps {
     git 'https://github.com/your-username/your-repo.git'
     }
     }
     stage('Run Script') {
     steps {
     sh 'python3 your_script.py'
     }
     }
     }
     }

      

5. Validation

• Push a commit to your GitHub repo and ensure Jenkins triggers the job automatically.

• The build should execute and print the output of your script.
