Kubernetes clusters and workloads are becoming bigger and bigger, but it’s not obvious how to test the scalability and performance aspects of them. In this session, you will learn about the performance test framework, created by the SIG-Scalability, that is used on a daily basis to keep Kubernetes scalable. We’ll introduce you to the ClusterLoader2, our “Bring Your Own Yaml” load test tool. We will show you how to create your own scalability test to exercise your workloads, how to run it, interpret the results and debug potential regressions. Last but not least, you’ll learn about Kubemark, a tool that simulates large Kubernetes clusters with much smaller compute footprint, and how to use it for performance testing.
