Description

Hi,
We want to enable export_custom_routes on a previously created google_compute_network_peering resource but it's a destructive operation when done through Terraform where it is not the case when done through the GCP Web UI.

Here is the output of the Terraform plan:

  # google_compute_network_peering.peering-production-data-prod must be replaced
-/+ resource "google_compute_network_peering" "peering-production-data-prod" {
      ~ auto_create_routes   = true -> (known after apply)
      ~ export_custom_routes = false -> true # forces replacement
      ~ id                   = "production-network/peering-production-data-prod" -> (known after apply)
        import_custom_routes = false
        name                 = "peering-production-data-prod"
        network              = "https://www.googleapis.com/compute/v1/projects/***/global/networks/production-network"
        peer_network         = "https://www.googleapis.com/compute/v1/projects/***/global/networks/data-prod-network"
      ~ state                = "ACTIVE" -> (known after apply)
      ~ state_details        = "[2020-03-25T07:38:13.328-07:00]: Connected." -> (known after apply)
    }

Is it possible to make this change non destructive ?
Thanks!

New or Affected Resource(s)

  name         = "peering-production-data-prod"
  network      = google_compute_network.production.self_link
  peer_network = data.google_compute_network.data-prod-network.self_link

  export_custom_routes = true
}

Hi is there an update on this issue? Making any changes to export or import custom routes should be a non-destructive operation on the peering connection. Making the same changes via the console or the SDK does not destroy the peering connection in question.

@anGie44 I see you have a pull request in for the change but do we know when we can expect the request to be merged/resolved?
