GCP Permission Changes

To improve the management of keys generated for tenant service accounts, the TelmaiServicesRunner requires three additional IAM permissions:

• iam.serviceAccountKeys.list

• iam.serviceAccountKeys.delete

These permissions will help ensure better control and cleanup of service account keys.

Not adding permissions does not affect running applications.
