Hello,

Would someone help me with that error? Can’t solve it with many attempts:

lb.tf

VPC network

resource “google_compute_network” “great-ilb_network” {
name = “great-l7-ilb-network”
auto_create_subnetworks = false
project = var.project_id
}

proxy-only subnet

resource “google_compute_subnetwork” “great-proxy_subnet” {
name = “great-l7-ilb-proxy-subnet”
ip_cidr_range = “10.0.0.0/24”
network = google_compute_network.great-ilb_network.self_link
}

backend subnet

resource “google_compute_subnetwork” “great-ilb_subnet” {
name = “great-l7-ilb-subnet”
ip_cidr_range = “10.0.1.0/24”
region = var.region
network = google_compute_network.great-ilb_network.self_link
}

MIG

resource “google_compute_instance_group_manager” “great-instance_group_manager” {
name = “my-great-instance-group-manager”
base_instance_name = “my-instance”
target_size = 3

version {
instance_template = google_compute_instance_template.great-instance_template.self_link
}
}

instance template

resource “google_compute_instance_template” “great-instance_template” {
name = “my-great-instance-template”
machine_type = var.vm_config.vm_type

disk {
source_image = “debian-cloud/debian-10”
auto_delete = true
}

network_interface {
network = “default”
access_config {}
}

metadata_startup_script = var.vm_config.vm_startup_script
}

Backend Service

resource “google_compute_backend_service” “fancy-fe-frontend” {
name = “fancy-fe-frontend”
project = var.project_id
port_name = “frontend”
health_checks = [google_compute_http_health_check.great-fe-frontend-hc.self_link]
backend {
group = google_compute_instance_group_manager.great-instance_group_manager.instance_group
}
protocol = “HTTP”
timeout_sec = 10
load_balancing_scheme = “INTERNAL_MANAGED”
}

HTTP Health Check

resource “google_compute_http_health_check” “great-fe-frontend-hc” {
name = “great-fancy-fe-frontend-hc”
project = var.project_id
check_interval_sec = 30
timeout_sec = 10
healthy_threshold = 1
port = 80
request_path = “/”
}

Firewall Rule

resource “google_compute_firewall” “fw-fe” {
name = “fw-fe”
network = google_compute_network.great-ilb_network.self_link
allow {
protocol = “tcp”
ports = [“80”]
}
source_ranges = [“0.0.0.0/0”]
target_tags = [“frontend”]
}

Error:

Anyone can suggest? I am not able to resolve it.
