The Mastering SaltStack book is one of my favorite Salt books. This book will get you past the basics of Salt and into what makes it a truly powerful automation framework. Tools like Salt Reactor, Thorium and Salt-SSH allow you to get the most out of Salt. The best ways to take Salt to the next level are revealed in this book, in an easy-to-understand way that will help you solve your problems.
Joseph Hall is likely the best person to write this book. He is not only a close friend, but has also been involved with the Salt project from the very beginning, including the early design of the Salt States system. Joseph is the second person to write code for Salt (apart from me). He was the first engineer hired by SaltStack.
