My problem

I am trying to build a personal CDN to share static file with my contacts. The design includes an S3 bucket, a CloudFront distribution and a subdomain registered via Route53, all configured using Terraform.

However, I can reach my files via S3 and Cloudfront, but not via my subdomain (cdn.adamatan.com).

What's working

S3

curl http://cdn.adamatan.com.s3.amazonaws.com/index.html

CloudFront

curl https://d36tl9ayobqfgg.cloudfront.net/index.html

What's broken

I can't get the files using the subdomain. Moreover, the nslookup for cdn.adamatan.com and adamatan.con do not work. I think that I've misconfigured Route53 somehow.

Configuration

Domain

Hosted Zone

Terraform configuration

  region  = "${var.aws_region}"
  profile = "personal"

My question

How can I map my subdomain (cdn.adamatan.com) to my cloudfront distribution (d36tl9ayobqfgg.cloudfront.net) using Terraform (preferably with SSL support)?
