Variable	Description	Example
org_id	(Required) Your GCP Org ID	"130342390179"

resource "google_organization_iam_custom_role" "teleskope" {
  role_id     = "teleskope-resource-manager-ro"
  org_id      = "{org_id}"
  title       = "Teleskope"
  description = "teleskope resource manager read only role"
  permissions = ["resourcemanager.projects.list", "resourcemanager.projects.get", "resourcemanager.folders.get", "resourcemanager.folders.list", "resourcemanager.organizations.get", "compute.regions.list", "storage.buckets.list", "storage.buckets.getIamPolicy"]
}

resource "google_organization_iam_member" "teleskope-resource-manager-ro-role" {

Configure Workload Identity Federation (Saas Only)

Teleskope Saas is run in an isolated AWS account. In order to grant Teleskope the ability to connect to GCP, you will need to configure workload identity federation.

Create Workload Identity Federation Pool

Go to https://console.cloud.google.com/ > Workload Identity Federation > Create Pool

• Name: teleskope-pool

• Pool id : teleskope-pool

• Provider:

  • Select Provider: AWS

  • Provider Name: teleskope-provider

  • AWS Account: {origin_aws_account_id}

Grant Access to Teleskope Service Account

Once pool is created, click Grant Access, and select the Teleskope service account you created above.

Terraform

Variable	Description	Example
origin_aws_account_id	(Required) AWS Account ID where Teleskope is deployed.	"012345678912"
project_id	(Required) Your GCP Project ID	"my-project-id"

resource "google_iam_workload_identity_pool" "teleskope-pool" {
	provider                  = google-beta
	display_name                       = "Teleskope AWS Pool"
	workload_identity_pool_id = "teleskope-pool"
  }
  
resource "google_iam_workload_identity_pool_provider" "teleskope-prov" {
	provider                           = google-beta
	workload_identity_pool_id          = google_iam_workload_identity_pool.teleskope-pool.workload_identity_pool_id
	workload_identity_pool_provider_id = "teleskope-provider"

	description                        = "AWS identity pool provider for teleskope"
	disabled                           = false
	aws {
	  account_id = "{origin_aws_account_id}"
	}
	depends_on = [google_iam_workload_identity_pool.teleskope-pool]
  }

resource "google_project_iam_member" "teleskope-member" {
  project = {project}
  service_account_id = google_service_account.teleskope.name
  member = "principalSet://iam.googleapis.com/${google_iam_workload_identity_pool.teleskope-pool.name}/*"
