How do I add my Grafana plugin folder from host to k8s?

[migge898]

I have developed a plugin with a local grafana setup (docker-compose) and now I want this to work with kube-prometheus.
I stumbled across jsonnet and thought that I could generate the manifests-files and add my plugin-folder, but I didn't get it to work and I couldn't find any examples for this neither.

For example I have this compose file:

version: '3.7'

services:
  grafana:
    image: grafana/grafana:latest
    ports:
      - 3000:3000/tcp
    volumes:
      - ./grafana-plugins:/var/lib/grafana/plugins
      - ./provisioning:/etc/grafana/provisioning
    environment:
      - TERM=linux
      - GF_LOG_LEVEL=debug
      - GF_DATAPROXY_LOGGING=true
      - GF_DEFAULT_APP_MODE=development

How could I achieve the same result with jsonnet as in the volumes definition?
Or are there better solutions without jsonnet?
