What Is Seed Job

We are using Jenkins to automate our day to day things but creating jobs in Jenkins manually is kind of a manual intervention so to automate jobs creation we use Seed Job. A seed Job is a combination of Jenkins modules and groovy code.

Note: To use seed job do install the plugin name Job DSL

Creating FreeStyle Job Using Seed Job

Here is a sample seed job creating a freestyle job.

job("test_freestyle_seed_job"){
    steps {
        shell('echo Hello World!')
    }
}

or

freeStyleJob("test_freestyle_seed_job"){
    steps {
        shell('echo Hello World!')
    }
}

Creating Pipeline Job Using Seed Job

Here is a sample seed job creating a pipeline job.

pipelineJob('test_pipeline_seed_job') {
    definition {
        cpsScm {
            scm {
                git {
                    remote {
                        github('lyfofvipin/jenkins_tutorials')
                        // url('https://github.com/lyfofvipin/jenkins_tutorials.git')
                    }
                }
            }
            scriptPath('jobs/First_Jenkinsfile')
        }
    }
}

Creating Jobs Inside Folder

Here is a script creating both the jobs.

folder('test_folder') // This will create a folder first
job("test_folder/test_freestyle_job"){
    steps {
        shell('echo Hello World!')
    }
}

pipelineJob('test_folder/test_pipeline_job') {
    definition {
        cpsScm {
            scm {
                git {
                    remote {
                        url('https://github.com/lyfofvipin/jenkins_tutorials.git')
                    }
                    branches("master")
                }
            }
            scriptPath('jobs/First_Jenkinsfile')
        }
    }
}

pipelineJob('test_pipeline_job_with_script') {
    definition {
        cps{
            script("""
pipeline{
    agent 'any'
    stages{
        stage("Stage_Name"){
            steps{
                sh "echo Test Stage.; pwd; hostname"
            }
        }
    }
    post{
        success{
            cleanWs()
        }
    }
}
        """)
        }
    }
}
