how to use K6_WEB_DASHBOARD in operator mode?

[CoffeeHi]

Hi guys, I deploy k6 operator in k8s cluster, but I don't know how to show K6_WEB_DASHBOARD when running TestRun CR, is it possible to show K6_WEB_DASHBOARD in distributed mode k6?
I have tried in TestRun CR, but does not work.

  runner:
    env:
      - name: K6_WEB_DASHBOARD
        value: "true"
      - name: K6_WEB_DASHBOARD_PORT
        value: "5665"
      - name: K6_WEB_DASHBOARD_OPEN
        value: "true"

Hi @CoffeeHi,

I'm sorry, but we don't have large expertise with the k6-operator.
So, let me transfer it to its specific repository, so any of its maintainers can try to help with this 🙇🏻

Hi @CoffeeHi, sorry for the delay! Are you trying to find one dashboard per test with aggregated data from all runners? Or are you trying to open a dashboard to one, specific runner and configuration does not work?

[CoffeeHi]

Hi @yorugac , I want to open a dashboard to one, as I known from https://grafana.com/docs/k6/latest/results-output/web-dashboard/ , I can get a runtime dashboard running K6_WEB_DASHBOARD=true k6 run script.js locally, how can I do this using k6-operator in k8s cluster?

Hi @CoffeeHi, it appears that you have already passed the dashboard option to the runners successfully:

  runner:
    env:
      - name: K6_WEB_DASHBOARD
        value: "true"

K6_WEB_DASHBOARD_OPEN makes no impact here because you're running k6 in a container: it isn't supposed to have access to your browser. But you can port-forward to any runner's dashboard with this:

kubectl port-forward pod/k6-sample-1-g4tnf 5665

And then open the dashboard in your browser just as you do with k6 standalone, that is by going to http://127.0.0.1:5665/.
Each runner will have its own dashboard.

Let me know if additional information is needed!

Does the k6 web dashboard captures all (aggregate) the distributed POD outcomes in its html report?

[yorugac]

Hi @vinaybudihal, if you mean aggregated values, then no, they are not captured. Each runner has its own dashboard, with metrics generated only by that runner. There is no "global" aggregated dashboard in k6 OSS and, therefore, there is no "global" dashboard in k6-operator. We provide aggregated dashboard via Grafana Cloud k6 product. Alternatively, you can set up your own aggregation with Prometheus and Grafana OSS.

I'm closing this issue as I believe initial question was answered. Please feel free to open a new one if something else comes up.
