Description
Compute Engine instances should not have public IP addresses to reduce potential attack surfaces, as public IPs enable direct access via the internet. Instances serving internet traffic should be configured behind load balancers, which provide an additional layer of security.
How to fix?
Remove the access_config attribute from the google_compute_instance.
Example Configuration
resource "google_compute_instance" "allowed" {
name = "test"
machine_type = "e2-medium"
zone = "us-central1-a"
boot_disk {
initialize_params {
image = "debian-11-bullseye-v20221102"
}
}
network_interface {
}
