Add Billing Reference to Projects

[tim-szostakowski-rewion]

Problem description

I'm always frustrated when I see that setting the Billing Reference for a project is only available in STACKIT Portal, but not in Terraform.

Proposed solution

Add the Terraform attribute to the project resource block.

resource "stackit_resourcemanager_project" "example" {
  parent_container_id = "example-parent-container-abc123"
  name                = "example-container"
  billing_reference = "string" 
  owner_email = "john.doe@stackit.cloud"
}

Hi @tim-szostakowski-rewion,
I've checked how the portal does this, since I couldn't find an API for this in the specs. It uses a label with a special name billingReference.
So this is already possible although a little bit hidden:

resource "stackit_resourcemanager_project" "tf-test-billing" {
  name = "tf-test-billing-ref-2"
  parent_container_id = var.organization_id
  labels = {
    "billingReference" = "fooref"
  }
  owner_email = "redacted@foo.com"
}

will create a project which shows up in portal with the specified billing reference:

I'll create an issue on our side to either improve the docs here, or introduce a billing_reference attribute like in your proposal. The current UX is subpar.

Alright. Thanks. I will try this out. But in this case you might want to update the description of the project ressource
