Associate your own domain name with the App Runner subdomain URL of your App Runner service.

After you call AssociateCustomDomain and receive a successful response, use the information in the CustomDomain record that's returned to add CNAME records to your Domain Name System (DNS). For each mapped domain name, add a mapping to the target App Runner subdomain and one or more certificate validation records. App Runner then performs DNS validation to verify that you own or control the domain name that you associated. App Runner tracks domain validity in a certificate stored in AWS Certificate Manager (ACM).
