Overview

This module will deploy the Jenkins Agent on Windows systems via the swarm jar and run it as a windows service using NSSM.

Module Dependencies

Please review the Dependencies to ensure you have all that is required in order for this module to function properly.

Module Description

The Windows Jenkins Agent will be deployed with the following defaults:

• swarm-client-3.3-jar-with-dependencies.jar
• mode: exclusive
• executors: 8
• labels: windows
• Agent Home: C:\opt\ci\jenkins
• Agent Workspace: C:\opt\ci\jenkins\workspace
• Jenkins Master: http://myjenkinsmaster.localhost:8080
• java: latest choco jdk8 package
• disableSslVerification swarm option enabled (override via hiera to undef if not needed)
• service account: LocalSystem

Puppet will create a windows service Jenkins_Agent and set it to run as the LocalSystem account

Any of the above defaults can be overridden via hiera as described in Setup Requirements.

If overriding the service account, the credentials for that user may be stored in an encrypted format in hiera via eyaml.

Classification Setup

This module includes a single class:

include jenkins_windows_agent

At a minimum, the jenkins_master_url, jenkins_master_user, and jenkins_master_pass variables should be overridden via hiera, Puppet Console, or inside of a resource like declaration:

class { 'jenkins_windows_agent':
  jenkins_master_url  => 'http://your_jenkins_master_url:8080',
  jenkins_master_user => 'your_jenkins_master_user',
  jenkins_master_pass => 'your_jenkins_master_pass',
}

What the jenkins_agent module affects

List of things that the module will alter:

 - Installs jdk8
 - Installs NSSM - the Non-Sucking Service Manager
 - Creates C:/tmp; C:/opt/ci/jenkins; C:/opt/ci/jenkins/workspace
 - Creates Jenkins_Agent service to run as LocalSystem via NSSM
 - Sets arguments / parameters for Jenkins_Agent service via NSSM
 - Manages Jenkins_Agent service

Setup Requirements

Please review the Module Dependencies section.

Override default values in the Puppet Console, or namespace the key/value pairs appropriately in the desired yaml hieradata file. At minimum, you'll need to override the jenkins_master_url, jenkins_master_user, and jenkins_master_pass variables to your environments specifications.

For example, to override these variables via hiera:

jenkins_windows_agent::jenkins_master_url: http://your_jenkins_master_url:8080
jenkins_windows_agent::jenkins_master_user: jenkins
jenkins_windows_agent::jenkins_master_pass: mypassword
