Sourcing grafana dashboard variables

[mmhh1910]

I can't seem to figure out how to source the "compartment_id" and "region_deployment" variables of the "oci-compute" and "oci-oke" grafana dashboards with my values from within terraform.

When applying the grafana.tf the values for these values are shown as "${VAR_COMPARTMENT_ID}" and "${VAR_REGION_DEPLOYMENT}" in the grafana GUI for the dashboards - which looks like some kind of planned variable expansion didn't take place.

I've tried to add these env variables for the grafan pods, but the values still show up as ""${VAR_COMPARTMENT_ID}" and "${VAR_REGION_DEPLOYMENT}":

VAR_REGION_DEPLOYMENT: "eu-frankfurt-1"
VAR_COMPARTMENT_ID: "/k8s"
GF_VAR_REGION_DEPLOYMENT: "eu-frankfurt-1"
GF_VAR_COMPARTMENT_ID: "/k8s"
