Test Kitchen + Puppet

Overview

Provisioning an Apache Software Foundation VM requires a lot of moving parts -- things with names like apt, gem, hiera, kitchen, puppet, and r10k. To make things easier, the Apache infrastructure team provides a base definition on top of which you install and configure 'modules'. Modules can be pretty much anything, examples being ldap and tomcat.

There are two sets of modules that you can draw from: 3rd party modules and [ASF])https://github.com/apache/infrastructure-puppet/tree/deployment/modules) modules.

As an alternative to a full configuration (which would involve DNS setup, etc), the recommended process is to copy the relevant configuration file from the infrastructure-puppet repository to the default-ubuntu1464, make changes to that subset of the configuration, and only copying, committing, and pushing the results when done.

Requirements

Vagrant
Ruby 2.0 or later
Virtualbox

Installation

Clone Repositories

git clone https://github.com/apache/infrastructure-puppet-kitchen
git clone https://github.com/apache/infrastructure-puppet

Install required gems

gem install bundler
cd <path to infrastructure-puppet repo>
bundle install

Get modules

cd <path to infra puppet repo>
./bin/pull # this will pull in all the 3rd party modules at the specified versions we use in production

Make modules useable

cd <path to puppet-kitchen repo>
cd puppet/modules
export ipr=<path to infra-puppet repo>
for i in $(ls $ipr/3rdParty); do ln -s $ipr/3rdParty/$i ./; done
for i in $(ls $ipr/modules); do ln -s $ipr/modules/$i ./; done

Boostrapping

kitchen create default
kitchen exec default -c 'sudo gem install deep_merge'
kitchen converge default

Usage

Basic

Start by copying a machine configuration from the data/nodes repository to puppet/data/node/default-ubuntu1464.yaml, editing it as needed, and then running:

kitchen converge default

This will bring up a vm, run puppet apply. From there, you can continue modifying the definition and/or writing new puppet module(s) (in puppet/modules/$module) and testing by rerunning the above command.

You can directly ssh into your virtual machine using the following command:

kitchen login default

If you have started a service like Apache httpd on this machine, you can access it at the following IP address: 192.168.33.2.

Modules

Modules are organized into two types: "third party" and "ASF custom".

Third party modules are listed in infrastructure-puppet/Puppetfile, and updated using the bin/pull command described above. Information on locating a module can be found at puppet labs documentation.

Custom modules are stored in infrastructure-puppet/modules/. Again, documentation on how to write a module can be found in the puppet labs documentation.

Cleanup

When done, you can take down and remove the VM with the following command:

kitchen destroy default
