Creating non-classic Global HTTPS Load Balancing

[jawnsy]

TL;DR

This module seems to create a classic HTTPS load balancer, without any option to create the new Envoy-based load balancers. Is there a way to create the new Envoy-based load balancers using this module? Happy to contribute something but would need some guidance

This can be done by adding a variable to the variables.tf file called load_balancing_scheme , setting the default to EXTERNAL and modifying three resources to use that variable, see below. In your tfvars file or wherever you are defining your variables, set load_balancing_scheme = "EXTERNAL" for classic load balancer and load_balancing_scheme = "EXTERNAL_MANAGED" for the new Envoy load balancer. I fully tested this and it works like a champ.

 resource "google_compute_global_forwarding_rule" "http" {
  project    = var.project
  count      = local.create_http_forward ? 1 : 0
  name       = var.name
  target     = google_compute_target_http_proxy.default[0].self_link
  ip_address = local.address
  port_range = "80"
  load_balancing_scheme = var.load_balancing_scheme
}

resource "google_compute_global_forwarding_rule" "https" {
  project    = var.project
  count      = var.ssl ? 1 : 0
  name       = "${var.name}-https"
  target     = google_compute_target_https_proxy.default[0].self_link
  ip_address = local.address
  port_range = "443"
  load_balancing_scheme = var.load_balancing_scheme
}

resource "google_compute_backend_service" "default" {
  provider = google-beta
  for_each = var.backends

  project = var.project
  name    = "${var.name}-backend-${each.key}"

  port_name = each.value.port_name
  protocol  = each.value.protocol
  load_balancing_scheme = var.load_balancing_scheme

If someone forks this module and adds these fixes, that would be great. Or a maintainer could provide a timeline for when they will add this.
