How to link an alert rule to a dashboard panel?

Grafana Alerting

I am using Terraform to automate rule_group and dashboard generation. But I don’t think this solution is terraform specific. I currently have a 1 - 1 mapping between a rule in a group and a panel in a dashboard. Based on the exported config of rules, it looks like rules are linked to panels using __dashboardUid__ and __panelId__. I was able to populate the __dashboardUid__ from the grafana_dashboard tf resource. But I am not sure how I should populate __panelId__.

Some of the approaches I tried:

  1. Specify panelId for each panel in grafana_dashboard. But looks like the panelId field in rules wants the value of id field.
  2. Specify id for each panel in grafana_dashboard. But looks like this value is ignored when I run terraform apply.
  3. Using the index of panel and rule. Both the panels and rules are generated by iterating over a yaml file. It looks like this is working but I am not 100% if this will always work.
