Why deploy dashboards with Terraform?

You already have a dashboard JSON file. You could import it manually through the Grafana UI, but that means every update requires a manual step, there’s no audit trail, and you can’t reproduce the deployment consistently.

Terraform solves this by treating dashboards as infrastructure:

• State management. Terraform tracks what’s deployed. It knows whether to create a new dashboard or update an existing one.
• Plan before apply. Preview exactly what will change before any modification touches your Grafana instance.
• One tool for everything. If your team already uses Terraform for servers, networks, or cloud resources, adding dashboards to the same workflow is natural.
• Reproducible deployments. The same terraform apply produces the same result every time, in every environment.
• Audit trail. Every deployment is tied to a Terraform state change, which you can track in version control.

When Terraform is the right choice

In the next milestone, you create a service account token that Terraform uses to authenticate to Grafana.
