how to request ACM using AWS default DNS for ELB

Question

I have an application running on AWS ELB and want to set up https listener. I tried to request an SSL certificate using AWS ACM but was unable to do because the ELB is using default AWS DNS name. Is it possible to request ACM for the DNS name like below?

abc-123455.us-east-2.elb.amazonaws.com

Answer 1

No, you can't create a certificate for a DNS name that you don't own. It is owned by AWS. What you can do is request an ACM for a DNS name that you do own like vamsi_domain.com. Then in Route53 you can use an alias (similar to CNAME) record to alias vamsi_domain.com as abc-123455.us-east-2.elb.amazonaws.com.
