net-address

Net Address Reservation Module

This module allows reserving Compute Engine external, global, and internal addresses.

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" }
  }
  global_addresses = {
    app-1 = {}
    app-2 = {}
  }
}
# tftest modules=1 resources=4 inventory=external.yaml

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    = "10.0.0.2"
      region     = var.region
      subnetwork = var.subnet.self_link
    }
  }
}
# tftest modules=1 resources=2 inventory=internal.yaml

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 = var.subnet.self_link
      ipv6 = {
        endpoint_type = "NETLB"
      }
    }
  }
  internal_addresses = {
    ilb = {
      ipv6       = {}
      purpose    = "SHARED_LOADBALANCER_VIP"
      region     = var.region
      subnetwork = var.subnet.self_link
    }
    vm = {
      ipv6       = {}
      region     = var.region
      subnetwork = var.subnet.self_link
    }
  }
}
# tftest modules=1 resources=3 inventory=ipv6.yaml

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

PSC addresses

module "addresses" {
  source     = "./fabric/modules/net-address"
  project_id = var.project_id
  psc_addresses = {
    one = {
      address = null
      network = var.vpc.self_link
    }
    two = {
      address = "10.0.0.32"
      network = var.vpc.self_link
    }
  }
}
# tftest modules=1 resources=2 inventory=psc.yaml

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
