Mastering Puppet 5

Roles and Profiles

The roles and profiles pattern became common knowledge in the Puppet community following Craig Dunn's seminal blog post (https://www.craigdunn.org/2012/05/239/), and has been rapidly taken up by the rest of the community. It's now a widely adopted pattern or best practice. It's a reliable way to build reusable, configurable, and refactorable site-wide configuration code, and it's an approach to dealing with the interfaces of your infrastructure—using the software development paradigms of encapsulation and abstraction.

Before the pattern developed, the Puppet language itself provided just two levels of abstraction, as follows:

But it soon became clear that further intermediate...

Summary of the pattern

The roles and profiles pattern adds two additional layers of abstraction between your node classification at the highest level and component modules at the lowest, thus providing three levels of abstraction in your Puppet modules. The following descriptions go from the most complex to the least:

  • Component modules: These are modules for the management of software for your business. There will no doubt be a bunch of these that you've downloaded from the Forge (for example, puppetlabs/apache, puppetlabs/mysql, hunner/wordpress, and so on), and no doubt also some that you have developed for your own business-specific purposes.

We've discussed these already at length in Chapter 1, Authoring Modules, so here's the rub:

  • Profiles: A set of encapsulated technology-specific classes that use one or more component modules and corresponding business...

Profiles

First, let's take a step back and consider what we want to achieve with profiles.

The overarching exercise is to produce usable chunks of technology that can be fitted together, in a building-brick fashion, to compose what we call in the industry these days technology stacks or solution stacks. The most well-known example of a stack would be the LAMP stack (Linux, Apache, MySQL, PHP), and more recently, Ruby or Python have sometimes superseded PHP as the primary scripting language. Node.js is being rapidly adopted across the industry, too.

Considering the LAMP stack, what we want to do is create chunks of technology for the Apache, MySQL, and PHP components. Profiles are, therefore, these smaller chunks of technology that will eventually comprise these full solution stacks. Profiles are the three building bricks that we piece together, as follows:

Let...

Roles

Let's take another step back and consider what we want to achieve with the roles part of the pattern. The overarching task is to piece together these building-brick-like profile classes into full tech stacks, which we call roles, and are now the second part of our full pattern:

Here you can see that we have taken the composite profiles from our previous example, and stacked them one on top of the other, to produce a full tech stack. We are also utilizing two additional shared profiles:

  • profile::base is included in all machines, including workstations. It manages security baselines and so on, using conditional logic for OS-specific profiles; for example, profile:: base::ubuntu, profile::base::redhat, and so on, as needed.
  • profile::server is included in all machines that provide a service over the network, and configures services such as NTP, firewalls,...

Summary

In this chapter, we have broadened our skills in writing Puppet modules to encompass the roles and profiles pattern, with reference to two special cases which provide a reliable way to build reusable, configurable, and refactorable site-wide configuration code.

Next, we stay in the development frame of mind, but look at how we can cover some of those possible edge cases where we may need to extend Puppet beyond its regular usage scenarios.

Description

Puppet is a configuration management system and a language written for and by system administrators to manage a large number of systems efficiently and prevent configuration drift. The core topics this book addresses are Puppet's latest features and mastering Puppet Enterprise. You will begin by writing a new Puppet module, gaining an understanding of the guidelines and style of the Puppet community. Following on from this, you will take advantage of the roles and profiles pattern, and you will learn how to structure your code. Next, you will learn how to extend Puppet and write custom facts, functions, types, and providers in Ruby, and also use the new features of Hiera 5. You will also learn how to configure the new Code Manager component, and how to ensure code is automatically deployed to (multiple) Puppet servers. Next, you will learn how to integrate Puppet with Jenkins and Git to build an effective workflow for multiple teams, and use the new Puppet Tasks feature and the latest Puppet Orchestrator language extensions. Finally, you will learn how to scale and troubleshoot Puppet. By the end of the book, you will be able to deal with problems of scale and exceptions in your code, automate workflows, and support multiple developers working simultaneously.

Who is this book for?

If you are a system administrator or developer who has used Puppet in production and are looking for ways to easily use Puppet in an enterprise environment, this book is for you. Some knowledge of writing simple configuration management modules would be necessary.

It is clear that the authors of this book have spent a ton of time using Puppet. This book does a fantastic job of covering all aspects of Puppet while focusing on points that improves the reader's Puppet mastery most effectively.Time isn't wasted reiterating things that are already available from Puppet docs, so in cases where they may be relevant, the book provides links them as extra reading. Therefore, Puppet users of all levels are able to benefit from the book. More advanced users can jump to whichever section they need, while newer users can dive deeper into the fundamentals by reading the linked material on Puppet docs.

Excellent daily resource for accelerating my knowledge of Puppet. The authors speak to routine complexities as well as the discrete one offs. The tone of the book drives me down a relaxing road of smoked coconut vapor topped with a an undercut of surgical precision. Fancy and clean.

This book is a fantastic dive in automation using Puppet. The author’s understanding of the components, including best practices and real world application, is a refreshing find. The topics hit throughout are immediately useful and demonstrate the “why” as opposed to best practice dictation.

Mastering Puppet 5 is a pretty apt title for this book. It covers everything that most people that are using Puppet will or should be utilizing. Jason and Ryan do a great job at showing what decisions should be made for Puppet to be used in production environments, including testing. Much of this goes beyond what is given in Puppet's own documentation and is more relevant to the production environments that most of us are utilizing Puppet in. Beginners (especially those in existing Puppet environments) and experts alike will find this book useful for both explanations as well as a reference for architectural decisions.

This book presents Puppet at a very low level, deep in the internals. The first chapter talks about writing "modules" without explaining what a module's is, or how it is used. It's a downward spiral from there, with more and more confusing topics presented and no explanation about how all the parts fit together. It seemed that the author was more concerned with showing how much he knows about Puppet than teaching us how to use it.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
