How to output attributes of instances from terraform.tfstate?

[ameyaptk]

I'm executing a GCP module to create a service-account.

main.tf

   resource "google_service_account" "gsvc_account" {
     account_id   = "xxx"
     display_name = ""
     project = "proj-yyy"
   }
   output "account_id" {
     value = "${google_service_account.gsvc_account.account_id}"
   }

Once the account is created, a terraform.tfstate file is created containing all details of the account.

terraform.tfstate

    {
      "version": 4,
      "terraform_version": "0.12.0",
      "serial": 3,
      "lineage": "aaaa-bbbb-cccc",
      "outputs": {
        "xxx": {
          "value": "xxx",
          "type": "string"
        }
      },
      "resources": [
        {
          "module": "module.gsvc_tf",
          "mode": "managed",
          "type": "google_service_account",
          "name": "gsvc_account",
          "provider": "provider.google",
          "instances": [
            {
              "schema_version": 0,
              "attributes": {
                "account_id": "xxx",
                "display_name": "",
                "email": "[email protected]",
                "id": "projects/proj-yyy/serviceAccounts/[email protected]",
                "name": "projects/proj-yyy/serviceAccounts/[email protected]",
                "policy_data": null,
                "project": "proj-xxx",
                "unique_id": "10891885"
              }
            }
          ]
        }
      ]
    }

As you can see above, in the module, I'm outputing the account_id input variable. Is there a way to output the attributes viz. id, name etc. so that they can be accessed by another module? The attributes are computed after the resource is created.

name can be outputted by the module, similar to any other field. This would need to be done in the module, and isn't something that can be resolved from the provider.

Perfect! That worked. Thanks! Is there a way to see which attributes can be 'outputed' and which can't?

Nvm. Found it in provider documentation- https://www.terraform.io/docs/providers/google/r/google_service_account.html
