Jotting down some common terraform error messages one might encounter in their terraform journey.

---

│   on main.tf line xxx, in resource "google_compute_global_address" "xxx":
│  region = "us-central1"
│ 
│ An argument named "region" is not expected here.

Solution : there isn't an argument called region for this resource. Remove that and the problem is resolved. Global IP is not bound to an region.

│   on main.tf line 182, in resource "google_compute_firewall" "allow-health-check":
│  182:     port_range = "80"
│ 
│ An argument named "port_range" is not expected here.

Solution :

There isn't an argumemnt named port_range. If you want to specify which port to open, then the block looks like below :

  allow {
        protocol = "tcp"
        ports    = ["80"]
    }

│ Error: Unsupported argument
│ 
│   on main.tf line 169, in resource "google_compute_instance_group_manager" "lb-backend-group":
│  169:     instance_template = google_compute_instance_template.lb-backend-template.self_link
│ 
│ An argument named "instance_template" is not expected here.

Solution :

You cant directly define tthe argment : instance_template. It has to be nested inside version,like beloow :

    version {
        instance_template = google_compute_instance_template.lb-backend-template.self_link
        name = "backend-servers"
    }
