Stage block structure in Jenkins - Mini Project: Build & Apply

Jenkins Pipeline: Stage Block Structure

📖 Scenario: You are setting up a Jenkins pipeline to automate your software build process. Jenkins pipelines use stages to organize tasks like building, testing, and deploying your code.

🎯 Goal: Build a simple Jenkins pipeline script with three stages: Build, Test, and Deploy. Each stage will have a simple echo command to show its execution.

📋 What You'll Learn

Create a Jenkins pipeline script using the pipeline block

Add a stages block inside the pipeline

Define three stages named Build, Test, and Deploy

Each stage should have a steps block with an echo command describing the stage

💡 Why This Matters

🌍 Real World

Jenkins pipelines automate software builds, tests, and deployments in many companies.

💼 Career

Understanding stage blocks is essential for DevOps engineers to create clear and maintainable CI/CD pipelines.

1

Create the pipeline and stages blocks

Write a Jenkins pipeline script starting with pipeline { and inside it add an empty stages { } block.

Jenkins

pipeline {
    stages {
        // Your code here
    }
}

Need a hint?

Start with pipeline { and add stages { } inside it.

2

Add the Build stage with echo step

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

Jenkins

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

Need a hint?

Use stage('Build') { steps { echo 'Building the project' } } inside stages.

3

Add Test and Deploy stages with echo steps

Add two more stages inside stages: Test with echo 'Testing the project' and Deploy with echo 'Deploying the project'.

Jenkins

pipeline {
    stages {
        stage('Build') {
            steps {
                echo 'Building the project'
            }
        }
        // Add Test and Deploy stages here
    }
}

Need a hint?

Add stage('Test') { steps { echo 'Testing the project' } } and stage('Deploy') { steps { echo 'Deploying the project' } } inside stages.

4

Print the complete pipeline script

Print the entire Jenkins pipeline script you created to verify the structure.

Jenkins

pipeline {
    stages {
        stage('Build') {
            steps {
                echo 'Building the project'
            }
        }
        stage('Test') {
            steps {
                echo 'Testing the project'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying the project'
            }
        }
    }
}

// Print the pipeline script below
// Your code here
