Pipeline stages and steps in Jenkins - Mini Project: Build & Apply

Jenkins Pipeline Stages and Steps

📖 Scenario: You are setting up a Jenkins pipeline to automate a simple software build process. The pipeline will have multiple stages to organize the workflow clearly.

🎯 Goal: Build a Jenkins pipeline script with three stages: Build, Test, and Deploy. Each stage will have one step that prints a message indicating the stage is running.

📋 What You'll Learn

Create a Jenkins pipeline script using the pipeline syntax

Define three stages named Build, Test, and Deploy

Add a steps block inside each stage

Inside each steps block, add a echo command that prints the exact message: "Building...", "Testing...", and "Deploying..." respectively

💡 Why This Matters

🌍 Real World

Jenkins pipelines automate software build, test, and deployment tasks in real projects, saving time and reducing errors.

💼 Career

Understanding pipeline stages and steps is essential for DevOps engineers and automation specialists to create reliable CI/CD workflows.

1

Create the pipeline skeleton

Write the initial Jenkins pipeline script with the pipeline block and an empty stages block.

Jenkins

pipeline {
    agent any
    stages {
        // Your code here
    }
}

Need a hint?

Start with pipeline { and add agent any to run on any available agent. Then add an empty stages block.

2

Add the Build stage with a step

Inside the stages block, add a stage named Build with a steps block that contains echo "Building...".

Jenkins

pipeline {
    agent any
    stages {
        // Add Build stage here
    }
}

Need a hint?

Use stage('Build') and inside it add steps { echo "Building..." }.

3

Add Test and Deploy stages with steps

Add two more stages inside stages: Test with echo "Testing..." and Deploy with echo "Deploying..." inside their steps blocks.

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo "Building..."
            }
        }
        // Add Test and Deploy stages here
    }
}

Need a hint?

Add stage('Test') and stage('Deploy') blocks with their respective steps and echo commands.

4

Print the pipeline script

Print the entire Jenkins pipeline script by writing the full script as output (simulate the final script).

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo "Building..."
            }
        }
        stage('Test') {
            steps {
                echo "Testing..."
            }
        }
        stage('Deploy') {
            steps {
                echo "Deploying..."
            }
        }
    }
}
// Print the pipeline script below
// Your code here

Need a hint?

Use println statements to print each line of the pipeline script exactly as it appears.
