Description

We would like create commited use discounts (only resource based commitments for now) via terraform. As we are defining all our google projects and resources via terraform, it would be very nice to also be able to create CUDs in a declarative way. I understand that these are a bit special resources as they can only be created and listed (updating and deleting is not supported). I also don't know yet how they would be tested as creating 'temporary' commitments doesn't seem to be supported. Maybe someone has an idea?

New or Affected Resource(s)

• google_compute_region_commitment

Potential Terraform Configuration

resource google_compute_region_commitment "test" {
  project = "test-1234"
  region = "us-east-1"
  name = "test-commitment"
  plan = "TWELVE_MONTH"
  type = "GENERAL_PURPOSE"
  resources {
    cpu = 2
    memory = 2048
    local_ssd = 2
    accelerator {
       type = "nvidia-tesla-v100"
       amount = 4
    }
  }
}

References

I did not find any github issues referencing CUDs so far.

I believe this is covered by the google_compute_reservation resource: https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_reservation

Maybe the documentation for that resource should be updated to mention CUD and Committed Use Discounts.

Oops, I'm mistaken apparently :facepalm:

Reservations and CUDs are too separate things...

Any updates here regarding the support of terraform for GCP CUDs creation and management...!

Hi, I will try to implement it. Testing might be challenging as CUDs can't be destroyed.
