Vapor has always made it straightforward to deploy your application to a custom domain, subdomain, or even wildcard subdomain. To take advantage of this feature, first, ensure the root domain is added as a domain to Vapor. This can be done either directly from the Vapor dashboard or by using the Vapor CLI: vapor domain example.com

Wildcard certificates provided by AWS Certificate Manager can only protect single-level subdomains, so to protect a multi-level subdomain, the subdomain must be explicitly added to the certificate.

As previously discussed, wildcard certificates cannot protect multi-level subdomains, so the multi-level subdomain must be explicitly defined in the vapor.yml file - relying on wildcard subdomains is not possible.
