Why Real Examples Help Learning

Using real-world examples aids learning because abstract concepts often feel detached from practical application. By showcasing realistic Jenkins pipelines, this blog post will help you understand how to implement scenarios that are similar to your daily workflow. Concrete examples teach you how to integrate approvals seamlessly, troubleshoot issues, and improve efficiency.

Additionally, providing examples specific to deployment, testing, and compliance ensures you’ll be able to adapt these techniques to different stages of your CI/CD pipelines.

Deployment Approval Workflow

One of the most common use cases for manual approvals is ensuring that deployments to production environments meet all quality requirements. Here’s how you can set up a basic deployment approval pipeline in Jenkins.

Example Jenkinsfile

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building the application...'
            }
        }
        stage('Test') {
            steps {
                echo 'Running tests...'
            }
        }
        stage('Approve Deployment') {
            steps {
                input message:'Do you approve deployment to production?', ok:'Approve Deployment'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying to production...'
            }
        }
    }
}

Why It Works

  • Pause for Human Review

The Approve Deployment stage ensures someone verifies the deployment before pushing critical changes to production.

  • Error Catching

This workflow gives teams a chance to fix bugs or address last-minute concerns before deploying live.

QA to Staging Pipeline with Approval

Another essential step in CI/CD is promoting code from the quality assurance (QA) environment to staging. Adding a manual approval step ensures that QA has completed their testing before staging begins.

Jenkinsfile Example

stage('Approve Staging') {
    steps {
        input message:'Has QA testing completed? Approve to move to Staging.', ok:'Promote'
    }
}

Benefits

  1. Enhanced Communication: QA and development teams are aligned.
  2. Reduced Bottlenecks: Ensures only tested and verified code reaches staging environments.

Approval with Custom Message & Submitter

Customizing approval prompts not only clarifies actions but also supports role-specific workflows. Limiting approvers to specific users adds an extra layer of security.

Jenkinsfile Example

stage('Specific Approval') {
    steps {
        input message:'Approve deployment?', ok:'Approve', submitter:'teamLead,qaManager', parameters:[text(name:'approvalReason', description:'Why is this approved?')]
    }
}

Why Customize?

Custom messages provide context, submitter restrictions ensure only authorized personnel can act, and optional parameters like approvalReason document decisions.

Timeout and Fallback Strategy

Manual approvals can sometimes halt pipelines if no response is received. Adding timeouts avoids such blockages.

Example Configuration

stage('Manual Approval') {
    steps {
        timeout(time: 1, unit: 'HOURS') {
            input message:'Approval required within 1 hour.'
        }
    }
}

Fallback Example

Add a fallback stage if approval times out or is rejected:

post {
    aborted {
        echo 'Approval step timed out. Reverting workspace to previous state.'
    }
}

This setup makes pipelines resilient to delays and missed approvals.

Notify Team Post-Approval

Effective communication ensures the entire team is on the same page during critical approval stages.

Slack Notification Example

post {
    success {
        slackSend(channel:'#team-updates', message:'Deployment has been approved and executed.')
    }
}

Rejecting or Skipping Approvals

Teams sometimes need the ability to reject or skip approvals mid-pipeline.

Reject Case

stage('Approval') {
    steps {
        script {
            def proceed = input(message:'Approve action?', parameters:[booleanParam(name:'accept', defaultValue:false, description:'Approval state')])
            if (!proceed) {
                error 'Pipeline approval rejected.'
            }
        }
    }
}

This example halts the pipeline upon rejection with a detailed status update.

Version Tagging with Approval

Automating version tags ensures deployment snapshots are saved after approval.

Example Snippet

stage('Tag Version') {
    steps {
        sh 'git tag -a Release-1.0 -m "Approved release 1.0" && git push --tags'
    }
}

This step improves traceability, an important feature for collaborative teams.

Secure Approvals in Enterprise Setups

Large organizations often have stringent compliance needs. To secure Jenkins approvals:

  1. Implement Role-Based Access Control (RBAC) using third-party solutions like LDAP or Jenkins plugins.
  2. Audit Logs: Enable detailed logs to track who performed each approval.
  3. Encrypted Communication: Always use HTTPS protocols to protect sensitive information.

Check out Jenkins’ official security documentation for advanced guidance.

FAQs

Q1. Why are manual approvals necessary in CI/CD?

Manual approvals reduce risks by allowing human intervention for quality checks, compliance reviews, and high-stakes deployments.

Q2. Can manual approvals include custom messages?

Yes, using the message or parameters field in the input directive.

Q3. What happens if no one approves the pipeline in time?

You can use timeouts to abort pipelines automatically after a set duration.

Q4. Can notifications be integrated into approval steps?

Yes, plugins like Slack or Email Extensions can be used for notifications.

Q5. Are manual approvals suitable for all pipelines?

No, they are best suited for critical decision points in regulated or high-risk environments.

Elevate your Jenkins pipelines by integrating manual approvals effectively. With the examples in this guide, you’ll not only implement approvals but optimize them for your team’s needs!
