Puppet 4: Language Essentials

by Andrew Mallett

Puppet is and has been the de-facto configuration management in Linux and Unix systems. With Puppet 4, it is even bigger and stronger and this course teaches you how to make best use of the Puppet language.

What you'll learn

As your server estate grows with more and more virtual systems, so does the difficulty of trying to keep your configurations consistent and reliable. The days of having a few servers to manage are long-gone, and there seems to be an array of different distributions that all require specific tools. Puppet is a mature and respected configuration management tool that is available free of charge as open-source software. In this course, Puppet 4: Language Essentials, you can learn Puppet quickly as the language is written simply with administrators and not developers in mind. First you'll learn how to provide consistent and reliable configuration results, and look at defining configurations as resources. Next, you'll learn to use logic to set the correct service names. Finally you'll be looking at how to restart services after configuration changes. After watching this course, you'll be able to create manifests yourself as well as defining your own configuration needs.
