Configure LBAC for data sources for Loki data source on Grafana Cloud

LBAC for data sources is available in private preview on Grafana Cloud for Loki created with basic authentication. Loki data sources for LBAC for data sources can only be created, provisioning is currently not available.

You cannot configure LBAC rules for Grafana-provisioned data sources from the UI. Alternatively, you can replicate the setting of the provisioned data source in a new data source as described in LBAC Configuration for New Loki Data Source and then add the LBAC configuration to the new data source.

Before you begin

To be able to use LBAC for data sources rules, you need to enable the feature toggle teamHttpHeaders on your Grafana instance. Contact support to enable the feature toggle for you.

  • Be sure that you have the permission setup to create a Loki tenant in Grafana Cloud
  • Be sure that you have admin data source permissions for Grafana.

Permissions

We recommend that you remove all permissions for roles and teams that are not required to access the data source. This will help to ensure that only the required teams have access to the data source. The recommended permissions are Admin permission and only add the teams Query permissions that you want to add LBAC for data sources rules for.

Task 1: LBAC Configuration for New Loki Data Source

  1. Access Loki data sources details for your stack through grafana.com
  2. Copy Loki details and create a CAP
    • Copy the details of your Loki setup.
    • Create a Cloud Access Policy (CAP) for the Loki data source in grafana.com.
    • Ensure the CAP includes logs:read permissions.
    • Ensure the CAP does not include labels rules.
  3. Create a new Loki data source
    • In Grafana, proceed to add a new data source and select Loki as the type.
  4. Navigate back to the Loki data source
    • Set up the Loki data source using basic authentication. Use the userID as the username. Use the generated CAP token as the password.
    • Save and connect.
  5. Navigate to data source permissions
