I am trying to configure the discourse dashboard via Ansible (or any means that involves editing files, passing ENV and not using the web interface). When I stick the dashboard in provisioning/dashboards
the dashboard shows up, but fails because datasource named "${DS_PROMETHEUS}", is not found.
If I import the Dashboard from the web interface I can correctly connect the Dashboard to the datasource and it works fine. How can I define DS_PROMETHEUS
by modifying the datasource.yml or passing an environment variable (or doing it some other way that I cannot imagine)?
