» Resource: aws_ec2_transit_gateway_vpc_attachment_accepter

Manages the accepter's side of an EC2 Transit Gateway VPC Attachment.

When a cross-account (requester's AWS account differs from the accepter's AWS account) EC2 Transit Gateway VPC Attachment is created, an EC2 Transit Gateway VPC Attachment resource is automatically created in the accepter's account. The requester can use the aws_ec2_transit_gateway_vpc_attachment resource to manage its side of the connection and the accepter can use the aws_ec2_transit_gateway_vpc_attachment_accepter resource to "adopt" its side of the connection into management.
