Chapter 7. Taking Salt Cloud to the Next Level

To many, Salt Cloud has become a crucial part of the stack of Salt tools. Originally designed for little more than creating and "Salting" virtual machines across multiple cloud hosting providers, its functionalities have grown to become much more. In this chapter, we'll discuss the following topics:

  • The basics of configuration

  • Extending configuration directives

  • Using SDB with Salt Cloud

  • Building custom deploy scripts

  • Working with cloud maps

  • Creating reactors to extend Salt Cloud

  • Building and using autoscale reactors

Take note that this chapter discusses how to manage compute nodes or instances, which generally refers to virtual machines. However, since some cloud hosting companies also provide cloud resources by creating an entire physical server or bare-metal instance available to the user, we will refer to them all collectively as compute instances.
