Part 1

Who Am I?

Who Are You?

Cookbook Testing

• foodcritic, chefspec, test-kitchen

• Get things right

• Keep things right

CI Servers

• System for running actions on every commit

• Identify problems early

• Jenkins, GoCD, TravisCI, Wercker, etc

Why Jenkins?

• Mature

• Extensible

• Good Chef Cookbook

• Free

Why Not Jenkins?

• TMTOWTDI

• XML, so much XML

• Automation is not a joy

Jenkins Cookbook

• Install Jenkins & Plugins

• Create jobs

• Run commands and scripts

Previously…

• Cooking With Jenkins

• ...and Kitchen, and Docker

Subsequently…

• Federated Jenkins with Chef

• github:erichelgeson/jenkins-chef-dsl/

Basic Configuration

• Install Plugins

• Configure Plugins

• Configure Jenkins

Installing Plugins

• Idempotent

• No dependency resolution

• Restart may be required

Plugin Configuration

• XML :(

• ...containing module version strings :((

• Hold nose and use cookbook_file

Jenkins Configuration

Creating Jobs

• jenkins_job

• Job DSL plugin

• Jenkins Job Builder

Pipeline

• Foodcritic

• Kitchen

• Publish

And after publish?

• That's why this is Part 1...

Foodcritic

Chefspec

• Publish JUnit test result report

Test Kitchen

• kitchen-docker

• Matrix jobs

• EnvInject and AnsiColor plugins

Berkshelf

• record version as artifact

Berkshelf

• curl -s https://jenkins.example/job/berks-upload/lastSuccessfulBuild/artifact/VERSION

Gluing it together

• Publish Artifact

• Copy Artifact

• Build Pipeline

Pipelines

• Build Pipeline plugin

• Build Graph View plugin

• Build Flow DSL

• ...and more

Build Pipeline

What's Missing?

• JUnit output from serverspec

Not the whole story...

• Testing a set of cookbooks

• Testing multiple nodes

• Promoting releases

Summary

• Not that hard to get started
