AWS VPC peering Terraform module

Terraform module which creates VPC peering resources on AWS.

These types of resources are supported:

• VPC peering connection
• VPC peering connection options
• VPC peering connection accepter
• Route

Description

This module can be used to setup VPC peering cross account, or within the same account, you just need to call the module multiple times, at least 2, one for the requester side and one for the accepter side.

Keep in mind that in order to accomplish this behaviour with the module we do not have any mandatory/required variables.

Usage

Requester side:

module "vpc_peering_requester" {
  source = "github.com/full360/terraform-aws-vpc-peering"

  requester = true

  accepter_owner_id   = "1234567890"
  accepter_vpc_id     = "vpc-654321"
  accepter_region     = "us-east-1"
  accepter_cidr_block = "172.16.0.0/24"
  requester_vpc_id    = "vpc-123456"

  requester_private_route_table_ids = [
    "rtb-987656a1e6becddb4",
  ]

  requester_public_route_table_ids = [
    "rtb-123456a1e6becddb3",
  ]

  tags = "${merge(map("Name", "my-peering-connection"), var.tags)}"
}

Accepter side:

module "vpc_peering_accepter" {
  source = "github.com/full360/terraform-aws-vpc-peering"

  accepter = true

  auto_accept               = true
  vpc_peering_connection_id = "pcx-1234567530b90e383"
  requester_cidr_block      = "172.32.0.0/24"

  accepter_private_route_table_ids = [
    "rtb-0987654321becddb2",
  ]

  accepter_public_route_table_ids = [
    "rtb-1234567890becddb1",
  ]

  tags = "${merge(map("Name", "my-peering-connection"), var.tags)}"
}
