Net Address Reservation Module

This module allows reserving Compute Engine external, global, and internal addresses. The module also supports managing VPC network attachments from service projects.

• Examples
  • External and global addresses
  • Internal addresses
  • IPv6 addresses
  • PSA addresses
  • PSC addresses
  • IPSec Interconnect addresses
  • PSC Network Attachments

Examples

External and global addresses

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  external_addresses = {
    one = { region = "europe-west1" }
    two = {
      region = "europe-west2"
      tier   = "STANDARD"
    }
  }
  global_addresses = {
    app-1 = {}
    app-2 = {}
  }
}
# tftest modules=1 resources=4 inventory=external.yaml e2e

Internal addresses

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  internal_addresses = {
    ilb-1 = {
      purpose    = "SHARED_LOADBALANCER_VIP"
      region     = var.region
      subnetwork = var.subnet.self_link
    }
    ilb-2 = {
      address    = "10.0.16.102"
      region     = var.region
      subnetwork = var.subnet.self_link
    }
  }
}
# tftest modules=1 resources=2 inventory=internal.yaml e2e

IPv6 addresses

You can reserve both external and internal IPv6 addresses.

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  external_addresses = {
    nlb = {
      region     = var.region
      subnetwork = module.vpc.subnets["${var.region}/ipv6-external"].self_link
      ipv6 = {
        endpoint_type = "NETLB"
      }
    }
  }
  internal_addresses = {
    vm = {
      ipv6       = {}
      region     = var.region
      subnetwork = module.vpc.subnets["${var.region}/ipv6-internal"].self_link
    }
  }
}
# tftest modules=2 resources=7 fixtures=fixtures/net-vpc-ipv6.tf inventory=ipv6.yaml e2e

PSA addresses

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  psa_addresses = {
    cloudsql-mysql = {
      address       = "10.10.10.0"
      network       = var.vpc.self_link
      prefix_length = 24
    }
  }
}
# tftest modules=1 resources=1 inventory=psa.yaml e2e

PSC addresses

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  psc_addresses = {
    one = {
      address = "10.0.0.32"
      network = var.vpc.self_link
    }
  }
}
# tftest modules=1 resources=1 inventory=psc.yaml e2e

IPSec Interconnect addresses

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  ipsec_interconnect_addresses = {
    vpn-gw-range-1 = {
      address       = "10.255.255.0"
      region        = var.region
      network       = var.vpc.self_link
      prefix_length = 29
    }
    vpn-gw-range-2 = {
      address       = "10.255.255.8"
      region        = var.region
      network       = var.vpc.self_link
      prefix_length = 29
    }
  }
}
# tftest modules=1 resources=2 inventory=ipsec-interconnect.yaml e2e

PSC Network Attachments

The project where the network attachment is created must be either the VPC project, or a Shared VPC service project of the host owning the VPC.

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  network_attachments = {
    gce-0 = {
      subnet_self_link = (
        "projects/net-host/regions/europe-west8/subnetworks/gce"
      )
      producer_accept_lists = [var.project_id]
    }
  }
}
# tftest modules=1 resources=1 inventory=network-attachments.yaml
