Continuous Integration and Continuous Deployment (CI/CD) pipelines automate the processes of building, testing, and deploying applications. But what happens when certain critical stages require manual oversight? Enter manual approval steps in Jenkins pipelines, a feature that brings flexibility, control, and a human touch to automation.

This guide will walk you through implementing manual approvals in Jenkins pipelines while breaking down their benefits, challenges, and use cases. By the end, you’ll know how to integrate manual approvals seamlessly into your CI/CD processes.

Introduction to Manual Approval in CI/CD

While automation is at the core of CI/CD frameworks, some critical steps benefit from human input. Manual approvals act as “gates” in your pipeline—pausing progress until an authorized individual reviews and approves the process.

These steps are particularly useful in sensitive environments, such as deploying to production or pushing updates to customers, where automation alone might not mitigate risk.

Benefits of Using Manual Gates in Pipelines

Implementing manual approval in your Jenkins pipelines offers several advantages:

  • Improved Quality Control: Catch errors or misconfigurations before they progress.
  • Enhanced Security: Minimize risks by requiring a manual review for sensitive actions.
  • Audit Trail Compliance: Maintain accountability with an approval log, satisfying regulatory requirements.
  • Flexibility for Team Dynamics: Allow teams to evaluate deployments based on business needs or last-minute checks.

By combining automation with manual checkpoints, your CI/CD pipeline becomes both dynamic and resilient.

Jenkinsfile Example with Input Step

Here’s how you can integrate a manual approval step in your Jenkinsfile using the input directive:

Example Jenkinsfile Code:

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building the application...'
                // Build steps
            }
        }
        stage('Test') {
            steps {
                echo 'Running tests...'
                // Test steps
            }
        }
        stage('Deploy Approval') {
            steps {
                input(message: "Approve deployment to production?", ok: "Proceed")
                echo 'Approval granted. Proceeding to deploy...'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying to production...'
                // Deploy steps
            }
        }
    }
}

Explanation:

  1. input(message) is used to pause the pipeline and display a prompt.
  2. The pipeline continues only after an authorized person clicks Proceed, ensuring all deployments are reviewed.

For more details, check Jenkins Input Step Documentation.

Role-Based Access Control in Approvals

Not everyone in a team should have the authority to approve sensitive stages. Using Role-Based Access Control (RBAC), you can assign specific rights and responsibilities. Jenkins supports fine-grained role management through plugins like Role Strategy Plugin.

Steps:

  1. Install the Role Strategy Plugin.
  2. Define roles such as approver, developer, or admin.
  3. Restrict the manual approval step to users with “approver” permissions only.

This ensures security and restricts access to critical controls.

Adding Manual Approval Before Deployment Stage

Introduce manual approvals where they matter the most—for instance, right before a production deployment. The Jenkinsfile example above demonstrates this effectively, but real-world pipelines often include staging environments for further review.

Consider using a multi-branch pipeline to target specific environments and add approvals based on the branch (e.g., staging, production).

Notifications and Alerts Integration

Integrating your manual approval steps with notification tools like Slack, Microsoft Teams, or email ensures approvers are aware as soon as their input is required.

Plugins for Notifications:

For example, configure Slack notifications to alert specific channels when a pipeline pauses for manual approval.

GitHub Trigger + Approval Use Case

One common use case is triggering Jenkins pipelines directly from GitHub and adding manual approvals:

  1. Configure the pipeline to trigger via pull request or merge to a specific branch.
  2. Use an approval gate to verify changes before they merge.

By setting up webhooks, developers can automate the process while retaining critical manual control for high-risk branches.

Best Practices for Secure Approvals

  1. Restrict Approvals: Use only trusted personnel for critical approvals.
  2. Log All Approvals: Keep a detailed audit trail of approval actions.
  3. Timeout Feature: Set time limits for pending approvals to avoid pipeline stalls.
  4. Training: Ensure your approvers understand the risks related to their role.

Common Issues and Troubleshooting

  1. Pipeline Stalls: If an approver overlooks the notification, use plugins to send reminder alerts.
  2. Timeouts: Configure realistic timeouts to prevent blocking builds.
  3. Role Misconfigurations: Double-check that the correct role mappings are active in the RBAC settings.

Final Thoughts and Summary

By adding manual approval steps, you strike a balance between automation and human oversight in Jenkins pipelines. These gates can prevent costly mistakes, ensure compliance, and manage risks in sensitive stages.

Start small—implement manual approvals in your deployment stage—and expand as needed. Use tools like Slack notifications and role-based permissions to streamline your process.

FAQs

1. What is the purpose of manual approval in Jenkins pipelines?

Manual approvals allow human oversight to validate sensitive stages, ensuring higher quality and security before progressing.

2. Can I notify users about pending approvals?

Yes, Jenkins supports integration with tools like Slack, email, and MS Teams for notifications.

3. How do I restrict approvals to specific users?

Using the Role Strategy Plugin, you can assign roles and restrict manual approvals to authorized personnel only.

4. What happens if no one approves within the set timeout?

You can configure the pipeline to abort or retry after a certain period. This avoids indefinite pipeline stalls.

5. Are manual approvals necessary for all CI/CD pipelines?

Not always. They are best reserved for critical stages like production deployments or when dealing with sensitive data.

By introducing manual approvals into your Jenkins pipelines, you’re not just enhancing process control but also building trust within your team and stakeholders.
