Chapter 4. Getting Tooled Up for Automated Chaos Engineering
Automated chaos experiments give you the power to potentially explore system weaknesses at any time. There are many turbulent condition–inducing tools out there, from the original Netflix Chaos Monkey for infrastructure-level chaos, to application-level tools such as the Chaos Monkey for Spring Boot. Here you are going to use the Chaos Toolkit and its ecosystem of extensions.
The Chaos Toolkit was chosen because it is free and open source and has a large ecosystem of extensions that allow you to fine-tune your chaos experiments to your own needs.1 The Chaos Toolkit also uses a chaos experiment format that you specify using YAML or JSON.2 As shown in the diagram in Figure 4-1, the toolkit takes your chaos experiment definition and orchestrates the experiment against your target system.

Don’t Sweat the Drivers
Don’t worry about the drivers mentioned in Figure 4-1 for now. You’ll learn all about Chaos Toolkit drivers in the following chapters when you use the toolkit to run experiments against various target systems. You’ll even learn how to extend your Chaos Toolkit by creating your own custom drivers (see Chapter 8).
Now it’s time to get the Chaos Toolkit installed. This means installing the Chaos Toolkit command-line ...
