Both the acceptor and requestor VPCs must have subnets associated with route tables


Name Default Description Required
namespace `` Namespace (e.g. cp or cloudposse) Yes
auto_accept true Automatically accept the peering (both VPCs need to be in the same AWS account) No
acceptor_allow_remote_vpc_dns_resolution true Allow acceptor VPC to resolve public DNS hostnames to private IP addresses when queried from instances in the requestor VPC No
requestor_allow_remote_vpc_dns_resolution true Allow requestor VPC to resolve public DNS hostnames to private IP addresses when queried from instances in the acceptor VPC No
stage `` Stage (e.g. prod, dev, staging) Yes
name `` Name (e.g. app or cluster) Yes
requestor_vpc_id `` Requestor VPC ID Yes
acceptor_vpc_id `` Acceptor VPC ID Yes
attributes [] Additional attributes (e.g. policy or role) No
tags {} Additional tags (e.g. map("BusinessUnit","XYZ") No
delimiter - Delimiter to be used between namespace, stage, name, and attributes No
enabled true Set to false to prevent the module from creating or accessing any resources No


When enabled, the DNS resolution features (acceptor_allow_remote_vpc_dns_resolution and requestor_allow_remote_vpc_dns_resolution) require that VPCs participating in the peering must have support for the DNS hostnames enabled. This can be done using the enable_dns_hostnames attribute in the aws_vpc resource.
