Create Private DNS Zones

Private DNS zones Are created identically to public zones, but must contain one or more VPCs in the vpcs list attribute. If no VPCs are defined, the zone will be considered a public zone.

            }
        ]
    }
}

Create Records within an Existing Zone

To create DNS records within an existing zone, define the zone ID for an existing zone using the id attribute in the dns_zones variable.
