Google Network Peering

This module allows creation of a VPC Network Peering between two networks.

The resources created/managed by this module are:

one network peering from local network to peer network
one network peering from peer network to local network

Basic Usage

Basic usage of this module is as follows:

module "peering" {
  source        = "./fabric/modules/net-vpc-peering"
  prefix        = "name-prefix"
  local_network = "projects/project-1/global/networks/vpc-1"
  peer_network  = "projects/project-1/global/networks/vpc-2"
}
# tftest modules=1 resources=2

Multiple Peerings

If you need to create more than one peering for the same VPC Network (A -> B, A -> C) you use a depends_on for second one to keep order of peering creation (It is not currently possible to create more than one peering connection for a VPC Network at the same time).

module "peering-a-b" {
  source        = "./fabric/modules/net-vpc-peering"
  prefix        = "name-prefix"
  local_network = "projects/project-a/global/networks/vpc-a"
  peer_network  = "projects/project-b/global/networks/vpc-b"
}

module "peering-a-c" {
  source        = "./fabric/modules/net-vpc-peering"
  prefix        = "name-prefix"
  local_network = "projects/project-a/global/networks/vpc-a"
  peer_network  = "projects/project-c/global/networks/vpc-c"
  depends_on    = [module.peering-a-b]
}
# tftest modules=2 resources=4

Route Configuration

You can control export/import of routes in both the local and peer via the routes_config variable. Defaults are to import and export from both sides, when the peer side only configured if the peering is managed by the module via peer_create_peering.

module "peering" {
  source        = "./fabric/modules/net-vpc-peering"
  prefix        = "name-prefix"
  local_network = "projects/project-1/global/networks/vpc-1"
  peer_network  = "projects/project-1/global/networks/vpc-2"
  routes_config = {
    local = {
      import = false
    }
  }
}
# tftest modules=1 resources=2  inventory=route-config.yaml

Variables

name	description	type	required	default
local_network	Resource link of the network to add a peering to.	`string`	✓
peer_network	Resource link of the peer network.	`string`	✓
peer_create_peering	Create the peering on the remote side. If false, only the peering from this network to the remote network is created.	`bool`		`true`
prefix	Optional name prefix for the network peerings.	`string`		`null`
routes_config	Control import/export for local and remote peer. Remote configuration is only used when creating remote peering.	`object({…})`		`{}`
stack_type	IP version(s) of traffic and routes that are allowed to be imported or exported between peer networks. Possible values: IPV4_ONLY, IPV4_IPV6.	`string`		`null`

Outputs

name	description	sensitive
local_network_peering	Network peering resource.
peer_network_peering	Peer network peering resource.
