grafana-image-renderer plugin not working with Grafana docker image #301

Open jonathanaylward opened 2 years ago

What happened: While trying to install the plugin: "grafana-image-renderer" I received the following error logs. They appear to be related to this issue and those linked to it. [https://github.com/grafana/grafana-image-renderer/issues/292] Is this still the only solution or has a fix been released and I'm experiencing the same problem for another reason?

What you expected to happen: I expected the plugin to install successfully as the comment here suggests that a fix may have been released in 8.2.1 [https://github.com/grafana/grafana-image-renderer/issues/292#issuecomment-939744311]

How to reproduce it (as minimally and precisely as possible): Attempt to install grafana-image-renderer via a helm chart on a grafana (8.2.3) instance running in kubernetes

Hello! The image renderer plugin does not currently work if it is installed in a Grafana Docker image. You need to build a custom Docker image, you'll find more documentation on that here: https://grafana.com/docs/grafana/latest/installation/docker/#build-with-grafana-image-renderer-plugin-pre-installed.

However, I would strongly recommend running the image renderer as a remote service in k8s instead (see "Remote rendering service installation" section here: https://grafana.com/grafana/plugins/grafana-image-renderer)
