Look on my works, ye Mighty, and despair!

Over the last few years, there has been a push for more “* as code” with Jenkins configuration. You can now specify job config using a Jenkinsfile, allowing auditing and code reviews, as well as a backup.

Combined with the Job DSL plugin, this makes it possible to create a seed job (using another Jenkinsfile, naturally) that creates all the jobs for a specific project.

pipeline {
    agent any

    options {
        timestamps ()
    }

    stages {
        stage('Clean') {
            steps {
                deleteDir()
            }
        }

        stage('Checkout') {
            steps {
                checkout scm
            }
        }

        stage('Job DSL') {
            steps {
                jobDsl targets: ['jobs/*.groovy', 'views/*.groovy'].join('\n')
            }
        }
    }
}

This will run all the groovy scripts in the jobs & views folders in this repo (once you’ve approved them).

For example:

pipelineJob("foo-main") {
    definition {
        cpsScm{
            scm {
                git {
                    remote {
                        github("examplecorp/foo", "ssh")
                    }
                    branch("main")
                }
            }
            scriptPath("Jenkinsfile")
        }
    }
    properties {
        githubProjectUrl('https://github.com/examplecorp/foo')
        pipelineTriggers {
            triggers {
                cron {
                     spec('@daily')
                }
                githubPush()
            }
        }
    }
}

And a view, to put it in:

listView('foo') {
    description('')

    jobs {
        regex('foo-.*')
    }

    columns {
        status()
        weather()
        name()
        lastSuccess()
        lastFailure()
        lastDuration()
        buildButton()
    }
}
