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.

Chapter 2. Controlling Your Minions with Remote Execution

In the previous chapter, we installed our Salt minion and Salt master and learned how to send our first commands. We're ready to control all the systems in our infrastructure from a central server, our Salt master.

In this chapter, we are going to expand upon what we discussed there. You will learn the following:

  • How a remote execution command is structured

  • How to target minions in various ways

  • Grains and how they are useful for remote execution

  • The basic relationship between minion and master

  • Practical examples of how you can use remote execution to make managing your servers easier
