terraform >= 0.13
aws >= 5.69.0

Providers

Name Version
aws >= 5.69.0

Resources

Name Type
aws_ec2_transit_gateway.this data source
aws_subnet.one data source

Inputs

Name Description Type Default Required
subnet_ids List of subnets to associate with the VPC attachment list(string) n/a yes
transit_gateway_id ID of the Transit Gateway string n/a yes
appliance_mode_support Whether Appliance Mode support is enabled. Valid values: disable, enable string "disable" no
cross_account Boolean whether this is a cross-account Transit Gateway shared via Resource Access Manager bool false no

transit_gateway_default_route_table_association Boolean whether the VPC Attachment should be associated to the Transit Gateway default route table bool true no
transit_gateway_default_route_table_propagation Boolean whether the VPC Attachment should propagate routes to the Transit Gateway propagation default route table bool true no
transit_gateway_route_table_association ID of the Transit Gateway route table to associate with the VPC attachment (an attachment can be associated with a single TGW route table) 
object({
    transit_gateway_route_table_id = string
  })
 null no
transit_gateway_route_table_propagations List of Transit Gateway route tables this VPC attachment will propagate routes to 
list(object({
