Jenkins Pipeline: Steps within Stages

📖 Scenario: You are setting up a Jenkins pipeline to automate a simple build process. The pipeline has stages, and each stage contains steps that perform specific tasks.Think of stages as chapters in a book, and steps as the sentences that tell the story in each chapter.

🎯 Goal: Build a Jenkins pipeline script with one stage named Build that contains two steps: one to print a message and another to run a shell command.

📋 What You'll Learn

Create a Jenkins pipeline with a pipeline block

Add a stage named Build

Inside the Build stage, add two steps: one echo and one sh

The echo step must print exactly Starting build...

The sh step must run the command echo Build complete

💡 Why This Matters

🌍 Real World

Jenkins pipelines automate software builds and tests, making development faster and less error-prone.

💼 Career

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

1

Create the pipeline and stage

Write a Jenkins pipeline script that starts with a pipeline block and contains one stage named Build. Use the agent any directive inside the pipeline.

Jenkins

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

Need a hint?

Start with pipeline {}, add agent any, then add stages {} with one stage('Build') {} inside.

2

Add the echo step inside the Build stage

Inside the steps block of the Build stage, add an echo step that prints exactly Starting build....

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                // Add echo step here
            }
        }
    }
}

Need a hint?

Use echo 'Starting build...' inside the steps block.

3

Add the shell command step inside the Build stage

Add a sh step inside the steps block of the Build stage that runs the shell command echo Build complete.

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Starting build...'
                // Add sh step here
            }
        }
    }
}

Need a hint?

Use sh 'echo Build complete' to run the shell command inside steps.

4

Print the pipeline script

Print the entire Jenkins pipeline script you wrote so far.

Jenkins

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Starting build...'
                sh 'echo Build complete'
            }
        }
    }
}

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

Need a hint?

In Jenkins, the pipeline script is saved as a Jenkinsfile. Here, just ensure your final script matches the previous steps.
