Terraform Version & Provider Version(s)

Terraform v6.12.0

Affected Resource(s)

google_cloud_run_v2_service

Terraform Configuration

resource "google_cloud_run_v2_service" "default" {
  name     = "cloudrun-service2"
  project  = var.project
  location = "us-central1"
  template {
      service_account = var.service_account
  }
}

Debug Output

N/A

Expected Behavior

The documentation for cloud_run_v2_service states that the containers block is Optional.

I would expect that I would be able to deploy a cloud_run_v2_service without a containers block based on the documentation.

Actual Behavior

When deploying the code above, I get this error:

╷
│ Error: Error creating Service: googleapi: Error 400: Violation in CreateServiceRequest.service.template.containers: Revision template must contain at least one container.
│ Details:

│         "field": "Violation in CreateServiceRequest.service.template.containers"
│       }
│     ]
│   }
│ ]

╵

Steps to reproduce

1. terraform apply

Important Factoids

The documentation for the previous cloud_run_service resource states that containers are Required, so I'm assuming the mistake is within the cloud_run_v2_service documentation.

I understand that this may not be a bug with cloud_run_v2_service resource, but more so just a problem with the documentation. I can create a pr to update the documentation if this is the case.

Confirmed documentation issue!

On terraform registry the argument containers of the template block code appears as Optional, but after running a terraform apply without setting any container it returns the shared error message

We may want to mark the field as Required in schema in a future major release too if this is the case.
