SaltStack is a powerful configuration management and automation suite designed to manage servers and tens of thousands of nodes. This book showcases Salt as a very powerful automation framework. We will review the fundamental concepts to get you in the right frame of mind, and then explore Salt in much greater depth. You will explore Salt SSH as a powerful tool and take Salt Cloud to the next level. Next, you'll master using Salt services with ease in your infrastructure. You will discover methods and strategies to scale your infrastructure properly. You will also learn how to use Salt as a powerful monitoring tool.
By the end of this book, you will have learned troubleshooting tips and best practices to make the entire process of using Salt pain-free and easy.Style and approach
This book follows a step-by-step conversational tone. Topics are covered in detail through examples and a user-friendly approach.
This book is for both new and existing Salt developers who are looking to build and write new Salt modules. Some prior Python development experience is expected.What You Will LearnUnderstand the working of Salt's Loader systemWrite several of the most common types of Salt modulesInteract between different kinds of modules and build new onesSubmit open source modules upstream to the Salt projectMake Salt interact with third-party services and applicationsIn Detail
Salt already ships with a very powerful set of tools, but that doesn't mean that they all suit your needs perfectly. By adding your own modules and enhancing existing ones, you can bring the functionality that you need to increase your productivity. Extending SaltStack follows a tutorial-based approach to explain different types of modules, from fundamentals to complete and full-functioning modules.
Starting with the Loader system that drives Salt, this book will guide you through the most common types of modules. First you will learn how to write execution modules. Then you will extend the configuration using the grain, pillar, and SDB modules. Next up will be state modules and then the renderers that can be used with them. This will be followed with returner and output modules, which increase your options to manage return data. After that, there will be modules for external file servers, clouds, beacons, and finally external authentication and wheel modules to manage the master.
With this guide in hand, you will be prepared to create, troubleshoot, and manage the most common types of Salt modules and take your infrastructure to new heights!Style and approach
