Distributed load testing using Kubernetes with k6 (k6 Office Hours #72)

We demonstrate how to run distributed load testing using Kubernetes with k6 and k6 operator. k6 can already run up to 40,000 virtual users from a single load generator, but if you want to scale that up further, you can use the Kubernetes operator to create a k6 custom resource within your cluster.

Really great informative video. If I have to use the standard k6 image in the k6-output-grafana-cloud.yaml what should be the value? If image is not specified in the yaml will it take the by default image of k6? Looking forward to your reply

Hello, is there any documentation to share some best practices on setting the resource limits per k6 pod? I know this depends on the complexity of test case and etc.. But was wondering if there is any benchmark statistics I can use to understand the initial resource limits I can put in place, or some practices on capacity planning?

Does k6-operator support browser module?

[qatester]

Hello, do you have a diagram reference on k6 Kubernetes design? Thanks.

[qatester]

possible to run the k6-browser base in Kubernetes?

Can I upload a supporting data.csv file to fetch some raw data for my scenario.js file in configmap?

[AbbeyLingord]

This is crazy, just seeing this vid makes me hate k6, do you actually provide some usable, CI-enabled solutions, without manually copying test scripts into a cluster?

[pKunal]

I followed steps, but getting below error


Any help?

I am facing this problem when I run k6s distributed tests in k8s cluster.
This is the log for 'starter'
LOG: sh: can't load library 'libdl.so.2'
