[Enhancement]: Transit Gateway Security Group Referencing Support

[phergoualch]

Description

AWS released a much anticipated feature to reference security groups across VPCs attached to a Transit Gateway. They added it to the Transit Gateway documentation and then rolled it back, so I'm not sure if this was a mistake and they are waiting for re:invent (no blog post has been published yet). Anyway, the feature is available in the GO SDK from version v1.48.1: https://github.com/hashicorp/terraform-provider-aws/pull/34492.

Affected Resource(s) and/or Data Source(s)

• aws_ec2_transit_gateway
• data_aws_ec2_transit_gateway
• aws_ec2_transit_gateway_vpc_attachment
• data_aws_ec2_transit_gateway_vpc_attachment

Potential Terraform Configuration

resource "aws_ec2_transit_gateway" "example" {
  description                        = "example"
  security_group_referencing_support = "enable"
}
