I am in the process of terraforming our Site_to_Site VPN connections in multiple regions and I cannot find any documentation on how to specify a region while creating the CGW. The below will create it in my default us-east-1 but I want to create this in us-west-1 and a host of others, but one thing at a time.
resource "aws_customer_gateway" "cgw-singapore" {
bgp_asn = 65000
ip_address = "111.111.111.111"
type = "ipsec.1"
tags = {
Name = "cgw-singapore"
}
