How to change plugin folder in kube-prometheus setup?


I have setup a Kubernetes cluster with this stack on Ubuntu 20.04.
I developed my first plugin for local Grafana (docker-compose) and it worked fine.
Now I want to be able doing the same with Grafana in above cluster, so that after restarting, nothing is lost or has to be configured again.
What is the best approach to connect my local plugin folder to that cluster?

Thanks in advance!
