• Using Gremlin to practice Chaos Engineering

To prepare for this exam, we recommend not just reading up on these topics, but to learn by doing. You can sign up for a free Gremlin trial account by clicking this link. Make sure to specify that your account is for certification purposes in the drop-down. If you are an AWS customer, you can also try out Gremlin on the AWS marketplace.

Lab Environments

These resources will help you set up a test environment for getting hands-on experience with Gremlin.

• Gremlin Playground is a virtual machine image for VirtualBox containing a full installation of the Gremlin agent and an example application. This is the easiest way to get started, but it requires VirtualBox.
• How to Install and Use Gremlin Locally with Kubernetes walks you through deploying the Gremlin agent onto a Kubernetes cluster. This tutorial works for any cluster using the Containerd, CRI-O, or Docker runtimes.
• How to Install and Use Gremlin with EKS walks you through deploying the Gremlin agent onto an Amazon EKS cluster.
• How to Install and Use Gremlin with Google Cloud Shell and Kubernetes walks you through deploying the Gremlin agent and an example application on a minikube cluster on Google Cloud Platform.

Recommended Reading

These resources will give you more info on Chaos Engineering, Gremlin, and the different use cases and applications of Chaos Engineering.

• Chaos Engineering: the history, principles, and practice: this tutorial presents the full history of Chaos Engineering, key concepts, and how organizations have successfully adopted it.
• Gremlin Scenarios: learn how to create and run a Scenario using Gremlin. A Scenario is a sequence of Gremlin attacks and Status Checks that you can use to recreate past outages or iteratively grow the blast radius of an experiment.
• Gremlin Agent Overview: this article explains how the Gremlin daemon works. The daemon is the binary that connects hosts to the Gremlin Control Plane.
• Gremlin Command Line Interface: the Gremlin CLI allows you to perform actions directly from a host running the Gremlin agent.
• Testing disaster recovery with Chaos Engineering: this tutorial explains Disaster Recovery Planning (DRP) and how you can test a DRP plan using Gremlin.
• Reducing MTTD for High-Severity Incidents: This ebook introduces the fundamentals of incident management classification and how SRE teams can reduce their time to detection.
