Jenkins

This Vagrant project will provision a VirtualBox machine with Jenkins. The intended use cases are

  • development on the ebrc_jenkins Puppet module
  • a playground for Jenkins job configuration before unleashing to production
    • including pre-flighting Jenkins upgrades
  • a sandbox for Jenkins plugin development

Only the master Jenkins server is provisioned at this time. Provisioning a separate worker node has not been implemented. Of course the master server can also serve as a worker so this single node will be sufficient for most use cases.

Prerequisites

The host computer needs the following.

Vagrant

Vagrant manages the lifecycle of the virtual machine, following by the instructions in the Vagrantfile that is included with this project.

https://www.vagrantup.com/downloads.html

You should refer to Vagrant documentation and related online forums for information not covered in this document.

VirtualBox

Vagrant needs VirtualBox to host the virtual machine defined in this project's Vagrantfile. Other virtualization software (e.g. VMWare) are not compatible with this Vagrant project as it is currently configured.

You should refer to VirtualBox documentation and related online forums for information not covered in this document.

Vagrant Librarian Puppet Plugin

This plugin downloads the Puppet module dependencies. Install the plugin with the command

vagrant plugin install vagrant-librarian-puppet

Vagrant Landrush Plugin (Optional)

The Landrush plugin for Vagrant provides a local DNS where guest hostnames are registered. This permits, for example, the rs1 guest to contact the iCAT enabled server by its ies.vm hostname - a requirement for iRODS installation and function. This plugin is not strictly required but it makes life easier than editing /etc/hosts files. This plugin has maximum benefit for OS X hosts, some benefit for Linux hosts and no benefit for Windows. Windows hosts will need to edit the hosts file.

EBRC uses a custom fork of Landrush. In an OS X terminal, run the following.

git clone https://github.com/mheiges/landrush.git
cd landrush
rake build
vagrant plugin install pkg/landrush-0.18.0.gem

If you have trouble getting the host to resolve guest hostnames through landrush try clearing the host DNS cache by running

sudo killall -HUP mDNSResponder.

You should refer to Landrush and Vagrant documentation and related online forums for information not covered in this document.

Usage

git clone git@github.com:EuPathDB/vagrant-jenkins.git

cd vagrant-jenkins

vagrant up

The default Jenkins website will be available at

http://ci.jenkins.vm:9191/

Setup and Configuration

For most use cases no configuration is needed.

Jenkins is provisioned using Puppet using adjustable parameters defined in the Hiera file puppet/environments/production/hieradata/common.xml

The configuration changes you may be interested in include the Jenkins version and network ports that the server listens on. These are defined in the ebrc_jenkins::instances Hiera hash.

The most important Puppet module in play here is ebrc_jenkins so see that module's documentation at https://github.com/EuPathDB/puppet-ebrc_jenkins for details.

Manual Puppet Run

When doing ebrc_jenkins Puppet module development you can trigger a run of the puppet agent with vagrant provision on the Vagrant host or by running the puppet agent on the guest.

sudo /opt/puppetlabs/bin/puppet apply --environment=production /etc/puppetlabs/code/environments/production/manifests/site.pp
