Puppet® Configuration and Administration

Puppet® Configuration and Administration

Audience

This course is for Unix/Linux systems administrators looking to automate their infrastructure.  It covers all the topics necessary for you to be totally au fait with the product and as it is delivered as a single seamless course it is considerably cheaper and one day shorter than other courses.

Prerequisites

Delegates should be experienced Unix/Linux systems administrators with some scripting knowledge (bash, sh, ksh, Perl or Python) and a broad understanding of the various system tasks relating to setting up and supporting Unix/Linux systems.

Knowledge of Ruby is not essential to see this product in action, since Ruby is only required to extend the current Puppet® system.

Duration

5 days. Hands on.

Course Objectives

Puppet® is an open source (with a commercial version aimed at the Enterprise market) systems management tool which provides a centralised configuration for all your UNIX, Linux and Apple systems, even on the other side of your firewall. What makes it different is that it speaks the local language of your target hosts allowing Puppet® to define tasks with generic instructions. These are called recipes and are so portable that they can be shared on the Puppet® website and used by all.

Puppet® is also flexible; being open source you can alter the code to suit your circumstances, and it's extensible. We will show you just how easy it is to add and amend functions.

Finally, it is better than most configuration tools because Puppet® uses Facter, which allows you to query host information and define custom facts on a host which can be used as variables by the Puppet® system.

This course is aimed at showing you how to set up and configure Puppet® and how to make the most of it, be it the open source or the enterprise version. As well as looking at the core features of Puppet®, including its configuration language, we will also provide you with a chance to go through a configuration of your own and manage a couple of nodes.

On completion delegates will understand what Puppet® can do and be able to:

  • Install and configure Puppet® servers and clients
  • Create and modify manifests
  • Modularise configurations
  • Use templates for file creation
  • Use the Puppet® file server
  • Generate reports
  • Extend Puppet's® abstraction layer

The course is comprised of lecture content and lab practicals. All sections contain exercises to help understand what you have just covered. Toward the end of the course a workshop will help you fully utilise the knowledge acquired up to that point to set up two or three clients and a Puppet® master.
