Configure data sources with LBAC

Configure data sources with label-based access control (LBAC)

Configuring data sources as code ensures consistent configuration across your environment. Adding label-based access controls (LBAC) restricts which teams can query specific data sources, implementing the principle of least privilege.

To configure data sources with access controls, complete the following steps:

1. Create a file named datasourceprometheus.tf for your Prometheus data source:

   hcl Copy

   resource "grafana_data_source" "prometheus" {
     type = "prometheus"
     name = "--Prometheus"
     url  = "https://prometheus.example.com"
   
     json_data_encoded = jsonencode({
       httpMethod = "POST"
     })
   }

2. Create a file named datasourcetestdata.tf for testing:

   hcl Copy

   resource "grafana_data_source" "testdata" {
     type = "testdata"
     name = "--TestData"
   }

3. Create a file named datasourceinfinity.tf for the Infinity plugin:

   hcl Copy

   resource "grafana_data_source" "infinity" {
     type = "yesoreyeram-infinity-datasource"
     name = "--Infinity"
   }

4. Create a file named datasource_perms.tf for label-based access control:

   hcl Copy

   resource "grafana_data_source_permission" "testdata_finance" {
     datasource_id = grafana_data_source.testdata.id
   
     permissions {
       team_id    = grafana_team.finance.id
       permission = "Query"
     }
   }
   
   resource "grafana_data_source_permission" "infinity_marketing" {
     datasource_id = grafana_data_source.infinity.id
   
     permissions {
       team_id    = grafana_team.marketing.id
       permission = "Query"
     }
   }

5. Apply the configuration:

   sh Copy

   terraform apply

The data sources are created with team-specific query permissions. Only Finance can query the TestData source, and only Marketing can query the Infinity source.

In the next milestone, you’ll create dashboard folders and apply team permissions.
