A quick recap

  • Vic and I are currently assigned to actively work on it

Repo

Guiding principles

Make it valuable Make it easy Make it fast Make it pretty

and always YAGNI, DRY and KISS

So.. what's new?

  • We have contibuted to job-dsl project
  • Templates are gone
    Why?
    It was fragile and brittle solution
  • Replaced by Groovy builders
    Why?
    Solves our passing parameters problems
    no "hard-coded" jobs
    Less Jenkins pollution

Here is a simple example

import jenkins.automation.utils.SiteMonitorJobBuilder

new SiteMonitorJobBuilder(
    name: "my-site-pulse-check",
    description: "Sample url pulse check job",
    cronSchedule: "@daily",
    urls: ["http://google.com","http://yourethemannowdog.ytmnd.com/"]
).build(this);

Slightly more involved example

import jenkins.automation.utils.JsJobBuilder

String basePath = 'JsJobSamples'
List developers = ['irina.muchnik@cfpb.gov', 'daniel.davis@cfpb.gov']
def repos = [
    [name: 'jenkins-automation', url:"https://github.com/cfpb/jenkins-automation@2.0"],
    [name: 'collab', url: "https://github.com/cfpb/jenkins-automation"]
]

folder(basePath)
{description 'This example shows how to create jobs using Job builders.'}

new JsJobBuilder(
    name: "$basePath/MyProjectJavascriptJob",
    description: 'An example using a job builder for a Javascript build jobs project.',
    repos: repos,
    emails:developers,
    use_versions: true )git a
.build(this)
