In this course, you will learn how to refactor your Puppet code to make use of templates, reduce the required files for a module, as well as how you can deliver parts of files, files, or complete sub-directories with Puppet.
There are many scenarios where adding functionality to your Puppet modules can make your work easier. In this course, Puppet 4: Working with Files and Templates, you'll learn how to make use of templates in your Puppet code and how you can deliver files with Puppet. First, you'll see how easily you can reduce the number of files a module requires by making use of variable data and templates. The original template language was Ruby, but now with Puppet 4 you can support both Ruby and Puppet templates. Next, you'll look at ways to deliver files and parts of files. Finally, you'll learn how you can deliver a complete folder structure if required, purging any unmanaged content using file\-line while concat delivers single lines or fragments of files allowing for autonomous edits to the managed files. By the end of the course, you will be able to create Puppet modules delivering configurations using templates, as well as allowing autonomous edits using file fragments.

Course Overview Hello everyone, and welcome. My name is Andrew Mallett and you might know me as The Urban Penguin, and I certainly hope that you are ready for the third Puppet course in this series, the Puppet 4: Working with Files and Templates course. Now you know that I work in the UK, and I have my own Linux training and consultancy company, and Puppet has always been my configuration tool of choice. I started using Puppet about seven or eight years ago to be able to complete classroom setups, and I'm still using it today. In this course, we're going to learn how we can refactor our Puppet code to make great use of templates, reducing the number of required files that we need within a module. We'll also see how we can deliver parts of files, files, or even complete subdirectory structures with Puppet. We're going to continue with the NTP theme that we've looked at in our previous courses, and we're going to especially look at purging resources, using ERB and EPP templates, and we'll look at how we can use concats to deliver file fragments. By the end of this course, you should be able to create exquisite Puppet modules, delivering configurations using templates, as well as allowing for autonomous edits using file fragments. Now of course you are going to need some basic knowledge of Linux and working at the command line, and an understanding of Puppet that can be gained from the Puppet 4: Language Essentials course.
