Is it enough to set GF_RENDERING_SERVER_URL and GF_RENDERING_CALLBACK_URL in the Grafana docker image for Grafana to recognize it should use the external renderer service?
I still get this:
lvl=warn msg=“Could not render image, no image renderer found/installed. For image rendering support please install the grafana-image-renderer plugin. Read more at Set up image rendering | Grafana documentation” logger=rendering
If I install grafana-image-renderer in my Grafana 7.3.6 it starts rendering the image but not sure whether it is done by independent rendering service or by plugin and strange thing is that it is only picking Grafana homepage image:
