Input step for manual approval in Jenkins - Mini Project: Build & Apply

Jenkins Pipeline Manual Approval with Input Step

📖 Scenario: You are automating a software deployment process using Jenkins. Before deploying to production, you want a human to review and approve the deployment manually.

🎯 Goal: Create a Jenkins pipeline script that pauses for manual approval using the input step before continuing to the deployment stage.

📋 What You'll Learn

Create a Jenkins pipeline script with a stage named Approval

Use the input step to pause the pipeline and ask for manual approval

After approval, print a message indicating deployment will proceed

💡 Why This Matters

🌍 Real World

Manual approval steps are common in deployment pipelines to ensure safety before releasing to production.

💼 Career

DevOps engineers often implement manual gates in CI/CD pipelines to balance automation with human oversight.

1

Create a basic Jenkins pipeline skeleton

Write a Jenkins pipeline script with a pipeline block and an empty stages section.

Jenkins

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

Need a hint?

Start with the basic Jenkins pipeline structure including pipeline, agent any, and stages blocks.

2

Add an Approval stage with an input step

Inside the stages block, add a stage named Approval that uses the input step with the message 'Approve deployment?'.

Jenkins

pipeline {
    agent any
    stages {
        stage('Approval') {
            steps {
                // Your code here
            }
        }
    }
}

Need a hint?

Use stage('Approval') and inside steps, add input message: 'Approve deployment?'.

3

Add a deployment stage that runs after approval

Add another stage named Deploy after the Approval stage. Inside steps, add a echo statement that prints 'Deployment started'.

Jenkins

pipeline {
    agent any
    stages {
        stage('Approval') {
            steps {
                input message: 'Approve deployment?'
            }
        }
        stage('Deploy') {
            steps {
                // Your code here
            }
        }
    }
}

Need a hint?

Add a new stage Deploy with a step that echoes 'Deployment started'.

4

Print confirmation after manual approval

Add a script block inside the Deploy stage's steps to print 'Deployment approved and started' using echo.

Jenkins

pipeline {
    agent any
    stages {
        stage('Approval') {
            steps {
                input message: 'Approve deployment?'
            }
        }
        stage('Deploy') {
            steps {
                // Your code here
            }
        }
    }
}

Need a hint?

Wrap the echo command inside a script block to print the confirmation message.
