Adding Grafana Image Renderer plugin with remote rendering

[bborovan]

Hello,

We are making use of the kube-prometheus operator with Grafana and want to enable the remote image rendering feature when we have Grafana send alerts by email. It seems in order to enable this built-in feature we need to enable the Grafana Image Renderer plugin.

The recommended way to now do so is to use remote rendering as described in the link above and in doing so set environment variables within the Grafana container to enable this, allowing Grafana to have the image rendering done outside of the Grafana container.

I can't see a straight forward (AKA easy) way to set the environment variables in the Grafana deployment done by the kube-prometheus helm chart, and don't see a way to set that in the config when installing the helm chart. Is there any easy way to enable this?

Thanks for any advice!
