in tests involving Grafana versions 12.2.0 and 12.2.1 (k8s), PNG images copied to the folder /usr/share/grafana/public/img/bg to be used as backgrounds appear with an error in the canvas. In the logs, a 404 error is shown. Is there another way to add images as backgrounds in the canvas? I can’t use URLs due to firewall policies.
I tried mounting the folder as a hostPath, tried moving it using kubectl cp, validated all permissions, and still the image doesn’t load.
I am facing the same issue! Let me know if something worked out for you. Thanks
Modifying the grafana/public/img/bg/ directory containing the stock Grafana background images is not currently a supported way of adding images to Canvas, nor will it become supported in the future.
Very creative hack though, I’m impressed!
Please refer to our documentation on the supported way to add a custom background image to your Canvas, by URL:
https://grafana.com/docs/grafana/latest/visualizations/panels-visualizations/visualizations/canvas/
you can move you background img in build folder then it show , img are present in both folder /public/build/img/bg
and public/img/bg then it will show , i don’t know it is bug or something else but after inspect the icon p7 it will show path to build folder that why i moved img to build folder. then restart the grafana service it will work for you thanks
