Summary: This is a summary of an article originally published by AWS DevOps Blog. Read the full original article here →

In this post, we discuss how you can use AWS Fault Injection Simulator (AWS FIS), a fully managed fault injection service used for practicing chaos engineering. AWS FIS supports a range of AWS services, including Amazon Elastic Kubernetes Service (Amazon EKS), a managed service that helps you run Kubernetes on AWS without needing to install and operate your own Kubernetes control plane or worker nodes.

For our action, we want aws:eks:terminate-nodegroup-instances to terminate worker nodes in our cluster.

Before we run our experiment, AWS FIS will ask you to confirm if you want to start the experiment.

First, we used a native action supported by AWS FIS to terminate instances from our Amazon EKS cluster.
