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: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

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 = "cloudposse/vpc-peering/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace        = "eg"
  stage            = "dev"
  name             = "cluster"
  requestor_vpc_id = "vpc-XXXXXXXX"
  acceptor_vpc_id  = "vpc-YYYYYYYY"
}

Using VPC tags

module "vpc_peering" {
  source = "cloudposse/vpc-peering/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace          = "eg"
  stage              = "dev"
  name               = "cluster"
  requestor_vpc_tags = {
    "kubernetes.io/cluster/my-k8s" = "owned"
  }
  acceptor_vpc_tags  = {
    Name = "legacy-vpc"
  }
}

context	Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as `null` to use default value. Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged.	`any`	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {} }	no

delimiter	Delimiter to be used between `namespace`, `environment`, `stage`, `name` and `attributes`. Defaults to `-` (hyphen). Set to `""` to use no delimiter at all.	`string`	`null`	no
enabled	Set to false to prevent the module from creating any resources	`bool`	`null`	no
environment	Environment, e.g. 'uw2', 'us-west-2', OR 'prod', 'staging', 'dev', 'UAT'	`string`	`null`	no
id_length_limit	Limit `id` to this many characters (minimum 6). Set to `0` for unlimited length. Set to `null` for default, which is `0`. Does not affect `id_full`.	`number`	`null`	no
label_key_case	The letter case of label keys (`tag` names) (i.e. `name`, `namespace`, `environment`, `stage`, `attributes`) to use in `tags`. Possible values: `lower`, `title`, `upper`. Default value: `title`.	`string`	`null`	no
label_order	The naming order of the id output and Name tag. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 5 elements, but at least one must be present.	`list(string)`	`null`	no
label_value_case	The letter case of output label values (also used in `tags` and `id`). Possible values: `lower`, `title`, `upper` and `none` (no transformation). Default value: `lower`.	`string`	`null`	no
name	Solution name, e.g. 'app' or 'jenkins'	`string`	`null`	no

requestor_allow_remote_vpc_dns_resolution	Allow requestor VPC to resolve public DNS hostnames to private IP addresses when queried from instances in the acceptor VPC	`bool`	`true`	no
requestor_route_table_tags	Only add peer routes to requestor VPC route tables matching these tags	`map(string)`	`{}`	no
requestor_vpc_id	Requestor VPC ID	`string`	`""`	no
requestor_vpc_tags	Requestor VPC tags	`map(string)`	`{}`	no
stage	Stage, e.g. 'prod', 'staging', 'dev', OR 'source', 'build', 'test', 'deploy', 'release'	`string`	`null`	no
tags	Additional tags (e.g. `map('BusinessUnit','XYZ')`	`map(string)`	`{}`	no
update_timeout	VPC peering connection update timeout. For more details, see https://www.terraform.io/docs/configuration/resources.html#operation-timeouts	`string`	`"3m"`	no
