Hi @hskhan

I would start making sure docker is correctly working in your environment.

Can you run k6’s “getting started” example and check if that works in your environment?

Create a basic script.js

import http from 'k6/http';
import { sleep } from 'k6';

export default function () {
  http.get('https://test.k6.io');
  sleep(1);
}

And run

  • docker run --rm -i grafana/k6 run - <script.js (Mac, Linux)
  • PS C:\> cat script.js | docker run --rm -i grafana/k6 run - if Windows (PowerShell).

Does that work? If it does, can you share the script/s you are runnning? I suspect you might be using an extension that requires a browser. Then you might need to build your own docker image with the requirements.

I hope this helps.

Cheers!

Hi
Thanks for the email, seem like this issue is due to following

Hi @hskhan

Thanks for getting back. I understand the error was happening when running k6 in MS Azure pipelines, and that the workaround described in DockerInstaller task permission issues on version 0.213.0 · Issue #17352 · microsoft/azure-pipelines-tasks · GitHub worked? And now it’s been fixed?

Let us know if otherwise.

Cheers!
