Delve into Kubernetes Chaos Engineering to discover system limits, simulate adverse effects, and improve resiliency. Learn about fault tolerance, high availability, and running experiments in a Kubernetes cluster.

Let’s face it, bad things happen in software engineering, often when you least expect it. Servers go down, there are spikes in traffic, you receive networking errors. Luckily, you can avoid these problems. Enter chaos engineering.
Chaos engineering is where you try to find the limits of a system and simulate adverse effects that might happen. These simulations then help you to determine the best way to improve your system and build up its resiliency.
This course is divided into various sections to get you used to the different types of experiments you can run in chaos engineering. You will start by learning how to destroy application instances in order to show you the importance of scaling, fault tolerance, and high availability.
You will then dive deep into other types of experiments such as destroying a network, draining and deleting nodes, and testing availability. Towards the end of the course, you will learn how to run experiments in a Kubernetes cluster.

The DevOps Toolkit: Kubernetes Chaos Engineering

# Installing the plugin

You probably remember that we had to install the `chaostoolkit-kubernetes` module to define Kubernetes-related chaos experiments. The same is true for Istio. We could, theoretically, define Istio-related actions, probes, and rollbacks as shell commands that would be applying YAML definitions and running `istioctl`. Nevertheless, that would be a waste of time since the `chaostoolkit-istio` module already provides some (if not all) Istio-related features. It will allow us to add some additional capabilities that we wouldn't have otherwise or, to be more precise, that would be much harder without it. So, let's install the module.


This lesson contains instructions on how to install the Chaos Toolkit Istio plugin and discover what is inside it.
