terraform-aws-vpc-peering

Terraform module to create a peering connection between two VPCs

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

Using VPC IDs

module "vpc_peering" {
  source           = "git::https://github.com/cloudposse/terraform-aws-vpc-peering.git?ref=master"
  namespace        = "eg"
  stage            = "dev"
  name             = "cluster"
  requestor_vpc_id = "vpc-XXXXXXXX"
  acceptor_vpc_id  = "vpc-YYYYYYYY"
}

Using VPC tags

module "vpc_peering" {
  source             = "git::https://github.com/cloudposse/terraform-aws-vpc-peering.git?ref=master"
  namespace          = "eg"
  stage              = "dev"
  name               = "cluster"
  requestor_vpc_tags = {
    "kubernetes.io/cluster/my-k8s" = "owned"
  }
  acceptor_vpc_tags  = {
    Name = "legacy-vpc"
  }
}
