Puppet

This training replaces the Puppet Master Curriculum and is recommended for certification as Puppet Certified Professional.

When working on large or small scale infrastructure configuration changes are normal business. When doing changes manually errors occur: differences in configuration files, unplanned termination of services, data get lost.

Normally one does use automation to reduce errors. All available solutions support system administrators in their daily business like packet installation, configuration changes or base system installation. The most significant difference between manual and automated configuration systems is based upon not doing work manually but describe the desired tasks within a central component and test them prior rollout. This reduces the work impact regarding amount of servers. The centrla component does not make differences whether to distribute changes to single machines or to thousands of servers.

One very popular solution for automation is Puppet. Puppet takes care that planned changes are executed on any platform. Puppet uses a declarative description like services definitions and server classes to be independent from the underlying operating system.

Puppet has the ability to generate configuration files. An example usage is changes on DNS servers without knwoing server names or IP addresses.

Within this course you will learn the required skills to plan, install and administrate Puppet configuration management systems. The main objective is to understand Puppet, gather practical experience with core functionality and basic understanding of complex data structure.
