Trying to Add Jenkins Approval Stage Before the Deployment of MuleSoft API in CloudHub? Here’s a Step-by-Step Guide!

Are you tired of manually tracking approvals and deployment of your MuleSoft API in CloudHub? Do you want to automate the process and ensure that only approved changes make it to production? Look no further! In this article, we’ll walk you through the process of adding a Jenkins approval stage before deploying your MuleSoft API in CloudHub.

Why Do You Need an Approval Stage?

Before we dive into the implementation details, let’s take a step back and understand why an approval stage is crucial in your CI/CD pipeline.

• Quality Assurance: An approval stage ensures that only tested and validated changes are deployed to production, reducing the risk of errors and downtime.
• Compliance: In regulated industries, approvals are essential for auditing and compliance purposes.
• Collaboration: An approval stage promotes collaboration between teams, ensuring that everyone is on the same page before changes are deployed.

Prerequisites

Before we begin, make sure you have the following prerequisites in place:

• A MuleSoft API deployed in CloudHub
• A Jenkins server set up with the necessary plugins (we’ll cover this later)
• A GitHub repository for your API code (optional but recommended)

Step 1: Configure Jenkins for CloudHub Deployment

In this step, we’ll configure Jenkins to deploy your MuleSoft API in CloudHub.

Install the following plugins in Jenkins:

• mulesoft-cloudhub-plugin for deploying to CloudHub
• github-plugin for integrating with your GitHub repository (if using)

Configure the MuleSoft CloudHub plugin by providing your CloudHub credentials and API details:

 CloudHub URL: https://anypoint.mulesoft.com
 Username: your-username
 Password: your-password
 API name: your-api-name
 API version: your-api-version
 Environment: your-environment

Step 2: Create an Approval Stage in Jenkins

In this step, we’ll create an approval stage in Jenkins that will gate the deployment to CloudHub.

Create a new stage in your Jenkins pipeline by adding the following code:

stage('Approval') {
  input {
    id: 'Approval'
    message: ' Approve deployment to CloudHub?'
  }
}

This will create a manual approval stage that requires a user input before proceeding to the next stage.

Step 3: Add a Deployment Stage in Jenkins

In this step, we’ll add a deployment stage that will deploy your MuleSoft API in CloudHub only after the approval stage has been successful.

Add the following code to your Jenkins pipeline:

stage('Deploy to CloudHub') {
  when {
    expression {
      env.APPROVAL == 'Approved'
    }
  }
  steps {
    muleCloudHubDeploy(
      apiUrl: 'your-api-name',
      apiVersion: 'your-api-version',
      environment: 'your-environment',
      username: 'your-username',
      password: 'your-password'
    )
  }
}

This stage will only execute if the approval stage has been successful (i.e., the `APPROVAL` environment variable is set to ‘Approved’).

Step 4: Configure Jenkins to Trigger the Pipeline

In this step, we’ll configure Jenkins to trigger the pipeline on changes to your GitHub repository (if using) or manually trigger the pipeline.

Configure the pipeline triggers by adding the following code:

triggers {
  scm('H/5 * * * *') //Trigger the pipeline every 5 minutes
  githubPush() //Trigger the pipeline on GitHub push events
}

Alternatively, you can manually trigger the pipeline by clicking the “Build Now” button in Jenkins.

Putting it all Together

Now that we’ve configured Jenkins for CloudHub deployment, created an approval stage, added a deployment stage, and configured Jenkins to trigger the pipeline, let’s put it all together!

Here’s the complete Jenkins pipeline code:

pipeline {
  agent any
  stages {
    stage('Approval') {
      input {
        id: 'Approval'
        message: ' Approve deployment to CloudHub?'
      }
    }
    stage('Deploy to CloudHub') {
      when {
        expression {
          env.APPROVAL == 'Approved'
        }
      }
      steps {
        muleCloudHubDeploy(
          apiUrl: 'your-api-name',
          apiVersion: 'your-api-version',
          environment: 'your-environment',
          username: 'your-username',
          password: 'your-password'
        )
      }
    }
  }
  triggers {
    scm('H/5 * * * *')
    githubPush()
  }
}

Conclusion

In this article, we’ve shown you how to add a Jenkins approval stage before deploying your MuleSoft API in CloudHub. This setup ensures that only approved changes are deployed to production, promoting quality, compliance, and collaboration.

By following these steps, you can automate your deployment process and ensure that your API is deployed efficiently and securely.
