I'm trying out the App Runner service and linking it to my domain. I'm unsure how to configure my DNS settings to prove domain ownership.

I'm unsure what kind of DNS records I need to configure - are they TXT records? CNAME?

Answer 1

AWS Support responded saying that all of the records type should be CNAME records .

Yes, it is CNAME. If you have other domains that have SSL configured via other AWS service, you'll also see they have added CNAME records for *.acm-validations.aws.
