SCM Timeout Fix - TerrenceMcGuinness-NOAA/global-workflow GitHub Wiki

To configure Jenkins to increase the timeout for checking out submodules during the SCM checkout step, you can adjust the SCM checkout options in your Jenkins pipeline configuration. Here’s how you can do it:

Step-by-Step Guide

1. Update Jenkins Pipeline Configuration:

   • Modify your Jenkinsfile to include a timeout for the SCM checkout step.

2. Set Timeout for Submodule Checkout:

   • Use the checkout step with a custom timeout.

Example Jenkinsfile Update

Here’s an example of how you can update your Jenkinsfile to increase the timeout for checking out submodules:

pipeline {
    agent any

    stages {
        stage('Checkout') {
            steps {
                script {
                    // Set a custom timeout for the SCM checkout step
                    timeout(time: 30, unit: 'MINUTES') {
                        checkout([
                            $class: 'GitSCM',
                            branches: [name: '*/main'](/TerrenceMcGuinness-NOAA/global-workflow/wiki/name:-'*/main'),
                            doGenerateSubmoduleConfigurations: false,
                            extensions: [
                                [$class: 'SubmoduleOption', disableSubmodules: false, parentCredentials: true, recursiveSubmodules: true, reference: '', trackingSubmodules: false],
                                [$class: 'CheckoutOption', timeout: 30] // Set the timeout for the checkout step
                            ],
                            submoduleCfg: [],
                            userRemoteConfigs: [url: 'https://github.com/your-org/your-repo.git'](/TerrenceMcGuinness-NOAA/global-workflow/wiki/url:-'https://github.com/your-org/your-repo.git')
                        ])
                    }
                }
            }
        }

        stage('Build') {
            steps {
                echo 'Building...'
                // Add your build steps here
            }
        }

        stage('Test') {
            steps {
                echo 'Testing...'
                // Add your test steps here
            }
        }

        stage('Deploy') {
            steps {
                echo 'Deploying...'
                // Add your deploy steps here
            }
        }
    }
}

Explanation

1. Timeout Block:

   • The timeout block is used to set a custom timeout for the SCM checkout step. In this example, the timeout is set to 30 minutes.

2. Checkout Step:

   • The checkout step is configured to use the GitSCM class with submodule options. The SubmoduleOption extension is used to enable recursive submodule checkout.
   • The CheckoutOption extension is used to set the timeout for the checkout step.

Summary

By updating your Jenkinsfile to include a custom timeout for the SCM checkout step, you can increase the time allowed for checking out submodules. This helps prevent timeout errors during the checkout process, especially for repositories with large submodules or slow network connections. Adjust the timeout value as needed based on your specific requirements.
