Learning SaltStack - Second Edition

By: Colton Myers

Overview of this book

SaltStack is one of the best infrastructure management platforms available. It provides powerful tools for defining and enforcing the state of your infrastructure in a clear, concise way. With this book learn how to use these tools for your own infrastructure by understanding the core pieces of Salt. In this book we will take you from the initial installation of Salt, through running their first commands, and then talk about extending Salt for individual use cases. From there you will explore the state system inside of Salt, learning to define the desired state of our infrastructure in such a way that Salt can enforce that state with a single command. Finally, you will learn about some of the additional tools that salt provides, including salt-cloud, the reactor, and the event system. We?ll finish by exploring how to get involved with salt and what'?s new in the salt community. Finally, by the end of the book, you'll be able to build a reliable, scalable, secure, high-performance infrastructure and fully utilize the power of cloud computing.

In this chapter, you learned how to make our states more flexible using Jinja2 templating. You learned the basic structures of Jinja2 and templated our apache state file so that it would run on both RedHat and Debian systems. You also learned how to define sensitive data in pillar and use that data in our states using Jinja2.

You now have all the tools you need to make flexible, modular states. In the next chapter, you'll learn how to better organize those files using topfiles in the state system, and you'll learn about environments in Salt.
