Dashboard issues when running through a docker container

Grafana k6
1

I am a bit confused around the behaviour of setting up the dashboard for presenting the k6 test results.

I am using docker desktop to manage my containers on windows but the containers themselves run through linux.

So far I have got everything working. I use a docker compose file to pull down the image and map my volumes /scripts and run command. My issue is that the k6 service only runs during the duration of the test. So for me to view the dashboard download the reports I have to quickly fire up a browser and go to localhost:6565 and download the reports before the service stops otherwise I get a ‘can’t find this page’ error.

Is there a way to automatically open a browser which I guess is another command in the docker compose and keep the service alive during the duration of when viewing the dashboard results.

I tried using the ENV variable ‘K6_WEB_DASHBOARD_OPEN’ but no luck and setting the restart command in the compose file to ‘restart unless stopped’ but that just kept repeating the same test because of the command run being set.

my compose file… any advice would be grateful. thanks.

Hey @tdsmithj! If I understood your question correctly, you’re not looking for the live dashboard to monitor while test runs, but for an HTML report once it finishes?

you are right. It is the HTML report.

Instead of opening the dashboard and downloading the report manually, you can specifyK6_WEB_DASHBOARD_EXPORT=/scripts/report.html and it will be automatically created during the test run.
