Instance template module does not allow an ephemeral IP address about terraform-google-vm

[morgante]

Can you try a configuration like this?

module "instance_template" {
  source          = "../../../modules/instance_template"
  project_id      = var.project_id
  subnetwork      = var.subnetwork
  service_account = var.service_account
  name_prefix     = "simple"
  tags            = var.tags
  labels          = var.labels
  access_config   = [{
    nat_ip = null
    network_tier = "PREMIUM"
  }]
}

I would also be interested in the possibility to generate ephemeral IP with this module.

This may require a change in the Terraform provider itself, like adding an access_config option such as ephemeral_external_ip = true.

I tried the above provided possible solution, but it did not create the ephemeral IP address.

Can you share the Terraform plan for creating the VM when you created this?

[shraddhajain01]

Here is the plan:

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

Hmm, based on the plan it definitely looks like an external IP should be getting assigned. Can you clarify where it's not getting one?

      + network_interface {
          + address            = (known after apply)
          + network            = (known after apply)
          + subnetwork         = "default"
          + subnetwork_project = (known after apply)

          + access_config {
              + assigned_nat_ip = (known after apply)
              + nat_ip          = (known after apply)
              + network_tier    = "PREMIUM"
            }
        }

Applied changes. Has an ephemeral external IP now. Thanks @morgante.
Closing issue.
