How to assign multiple external IP to a google cloud instances using terraform

Question

I am able to add an external IP to the instance by the following code.

network_interface {
subnetwork = "${europe-staging-subnetwork.self_link}"


access_config {
  nat_ip = "${google_compute_address.external_ip.address}"
}
}

resource "google_compute_network" "staging-network" {
name                    = "staging-network"
auto_create_subnetworks = "false"
}
resource "google_compute_subnetwork" "europe-staging-subnetwork" {
name          = "europe-staging-subnetwork"
region        = "europe-west1"
ip_cidr_range = "#.#.#.#/16"
network       = "${google_compute_network.staging-network.self_link}"
}

But How will I assign multiple external IP to an instances?

Answer 1

You can use multiple network interfaces to have multiple external IPs. The network interfaces need to be configured while creating the instance and these cannot be modified or deleted after the instance has been created.
