[ibm_tg_gateway] Error: A gateway with the same name already exists.

ocofaigh commented 2 years ago

We intermittently see an issue where transit gateway creation fails with Error: A gateway with the same name already exists. However, we are using a random prefix so this should not be the case.

As you can the plan contains tg name called landing-3156-transit-gateway:

 2022/11/19 17:01:14 Terraform plan |   # module.landing_zone.ibm_tg_gateway.transit_gateway[0] will be created
 2022/11/19 17:01:14 Terraform plan |   + resource "ibm_tg_gateway" "transit_gateway" {
 2022/11/19 17:01:14 Terraform plan |       + created_at              = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + crn                     = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + global                  = false
 2022/11/19 17:01:14 Terraform plan |       + id                      = (known after apply)

 2022/11/19 17:01:14 Terraform plan |       + name                    = "landing-3156-transit-gateway"
 2022/11/19 17:01:14 Terraform plan |       + resource_controller_url = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + resource_crn            = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + resource_group          = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + resource_group_name     = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + resource_name           = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + resource_status         = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + status                  = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + tags                    = (known after apply)
 2022/11/19 17:01:14 Terraform plan |       + updated_at              = (known after apply)
 2022/11/19 17:01:14 Terraform plan | 
 2022/11/19 17:01:14 Terraform plan |       + timeouts {
 2022/11/19 17:01:14 Terraform plan |           + create = "30m"
 2022/11/19 17:01:14 Terraform plan |           + delete = "30m"
 2022/11/19 17:01:14 Terraform plan |         }
 2022/11/19 17:01:14 Terraform plan |     }

yet the apply fails with:

 2022/11/19 17:08:17 Terraform apply | Error: A gateway with the same name already exists.
 2022/11/19 17:08:17 Terraform apply | 
 2022/11/19 17:08:17 Terraform apply |   with module.landing_zone.ibm_tg_gateway.transit_gateway[0],
 2022/11/19 17:08:17 Terraform apply |   on ../../transit_gateway.tf line 6, in resource "ibm_tg_gateway" "transit_gateway":
 2022/11/19 17:08:17 Terraform apply |    6: resource "ibm_tg_gateway" "transit_gateway" {

After checking manually in the UI, I can see that the test did create the transit gateway:

So this seems to be a provider (or backend UI issue) where the resource is actually being created, but perhaps a success response is not coming in time, and perhaps a retry is attempted.

I have not (yet) reproduced with trace logs, but creating to issue to see if this may be a known issue, or incase others have hit it
