The webinar discusses the use of Puppet and its architecture, highlighting the challenges of non-production setups and introducing Oscar for easier auto-provisioning with VirtualBox. Oscar provides native plugins and rapid deployment capabilities, requiring tools like VirtualBox and Vagrant for setup. The session wraps up with additional resources and information about upcoming events related to Icinga and job opportunities at Olindata.

Challenges in non-production
Outside of your production environment there are many
instances where you want to test things quickly, locally:
•New module
•New development environment
•Automated tests
•Reproducing issues
Setting up a new master and desired agents each time is
cumbersome, so let’s make that easier!

7. Webinar May 2016
Why Oscar-stack
Using Oscar instead of home-made scripts provides benefits:
•Native virtualbox plugins
•Extendable, eg. not use PE but use FOSS puppet
•Create complex puppet deployments fast

8. Webinar May 2016
Oscar Prerequisites
Make sure you have installed the following on your host
machine:
•virtualbox (http://virtualbox.org)
•vagrant (https://www.vagrantup.com/)
•vagrant plugin oscar (https://github.com/oscar-stack/oscar)
You can install oscar plugin for vagrant with the following
command:
vagrant plugin install oscar

About VirtualBox and Vagrant
VirtualBox Vagrant
• Desktop tool for local
virtualisation
• Similar to vmware
player/vmware fusion
• Great for local vms / testing
• Requires significant
resources on host system
https://www.virtualbox.org/
• Wrapper around virtualbox
• Easily provision new
machines
• Idempotent (ie. the resulting
boxes will always look the
same given the same
vagrantfile)
• Flat file configuration, great
for version control and
distribution with your tool’s
code
https://www.vagrantup.com/

10. Webinar May 2016
•Boxes are standard vms packaged in a easy to use format
• They form the base of a vagrant environment
•Check installed boxes:
# vagrant box list
puppetlabs/centos-6.6-64-nocm (virtualbox, 1.0.2)
puppetlabs/centos-7.0-64-nocm (virtualbox, 1.0.2)
puppetlabs/debian-7.8-64-nocm (virtualbox, 1.0.1)
puppetlabs/ubuntu-14.04-64-nocm (virtualbox, 1.0.2)
Vagrant boxes
