I am attempting to write automation to deploy instances in a shared VPC on GCP. I have a host network project and a service project. I can create a static internal IP address resource in the host project (resource "google_compute_address" "internal") in which I specify the VPC host project (NET_HUB_PROJ) but I am unable to use it when creating the instance. I receive the following error:

  • It is not being used by any other resource. I can confirm it has been created in the host networking project (prototype-network-hub) but not applied to any resource. The error msg alludes to that. It just specifies that it is reserved by the project. One interesting thing to note is using TF, I see an internal IP reservation: evernote.com/l/AfdR3FOkeFZPubjfrEWmcVA1II2uk8cU3qE, but when manually reserved as seen in the picture in my above post, it does not.

EDIT (new answer):
Per the GCP documentation, the static internal IP must belong to the service project (not the host network project as in your code) if you're looking to reserve internal IP on a shared VPC in a different project. See here:
https://cloud.google.com/vpc/docs/provisioning-shared-vpc#reserve_internal_ip



Seeing as a shared-vpc is unlikely to be found in your TF codebase, you'll have to use data to get the self_link of the subnetwork to use for google_compute_address. Something like the following:



data "google_compute_subnetwork" "subnet" 
name = "$var.NET_HUB_SUBNETWORK"
project = "$var.NET_HUB_PROJ"
region = "$var.NET_HUB_REGION"


resource "google_compute_address" "internal"
name = "$var.NAME-int-ip"
address_type = "INTERNAL"
address = "$var.PRIVATE_IP"
subnetwork = "$data.google_compute_subnetwork.subnet.self_link"



This should create the resource under your service project, yet with an address within the designated subnet.



When you deploy your instance you should see it referenced under the internal_ip column on your VM instances tab for the assigned instance.



(old answer for posterity):
Unfortunately, google_compute_address doesn't contain a subnetwork_project like google_compute_instance. A fix around this is to provide a full URL to the subnetwork field in google_compute_address. Something like the following:



resource "google_compute_address" "internal" 
name = "$var.NAME-int-ip"
address_type = "INTERNAL"
address = "$var.PRIVATE_IP"
subnetwork = "https://www.googleapis.com/compute/v1/projects/$var.NET_HUB_PROJ/regions/$var.NET_HUB_REGION/subnetworks/$var.NET_HUB_SUBNETWORK"

        region = "$var.NET_HUB_REGION"


        resource "google_compute_address" "internal"
        name = "$var.NAME-int-ip"
        address_type = "INTERNAL"
        address = "$var.PRIVATE_IP"
        subnetwork = "$data.google_compute_subnetwork.subnet.self_link"



        This should create the resource under your service project, yet with an address within the designated subnet.



        When you deploy your instance you should see it referenced under the internal_ip column on your VM instances tab for the assigned instance.



        (old answer for posterity):
        Unfortunately, google_compute_address doesn't contain a subnetwork_project like google_compute_instance. A fix around this is to provide a full URL to the subnetwork field in google_compute_address. Something like the following:



        resource "google_compute_address" "internal" 
        name = "$var.NAME-int-ip"
        address_type = "INTERNAL"
        address = "$var.PRIVATE_IP"
        subnetwork = "https://www.googleapis.com/compute/v1/projects/$var.NET_HUB_PROJ/regions/$var.NET_HUB_REGION/subnetworks/$var.NET_HUB_SUBNETWORK"

        EDIT (new answer):
        Per the GCP documentation, the static internal IP must belong to the service project (not the host network project as in your code) if you're looking to reserve internal IP on a shared VPC in a different project. See here:
        https://cloud.google.com/vpc/docs/provisioning-shared-vpc#reserve_internal_ip



        Seeing as a shared-vpc is unlikely to be found in your TF codebase, you'll have to use data to get the self_link of the subnetwork to use for google_compute_address. Something like the following:



        data "google_compute_subnetwork" "subnet" 
        name = "$var.NET_HUB_SUBNETWORK"
        project = "$var.NET_HUB_PROJ"
        region = "$var.NET_HUB_REGION"


        resource "google_compute_address" "internal"
        name = "$var.NAME-int-ip"
        address_type = "INTERNAL"
        address = "$var.PRIVATE_IP"
        subnetwork = "$data.google_compute_subnetwork.subnet.self_link"



        This should create the resource under your service project, yet with an address within the designated subnet.
