How do I creating a Route53 DNS record for my beanstalk environment?

I'd like to create an internally well-known dns name that points to the ELB of my (internal ELBScheme) elastic beanstalk environment that's hosting an internal REST API.

I tried adding an .ebextensions entry that looked like this:

"eb-env-dns-name" : {
  "Type" : "AWS::Route53::RecordSetGroup",
  "Properties" : {
    "HostedZoneName" : "mydomain.com.",
    "Comment" : "alias targeted to elastic beanstalk LoadBalancer.",
    "RecordSets" : [
      {
        "Name" : "eb-env.mydomain.com.",
        "Type" : "A",
        "AliasTarget" : {
            "HostedZoneId" : "ABC123XYZ",
            "DNSName" : { "Fn::GetAtt" : ["AWSEBLoadBalancer","DNSName"] }
        }
      }
    ]
  }
}

The idea being that I could then access my internal application by making REST calls against the domain "eb-env.mydomain.com".

It didn't fail, but didn't work either: nothing showed up in my hosted zone on Route53.

I'm having trouble finding useful documentation on this stuff - can anyone point me at an example of how I might do this with the .ebextensions mechanism? Or should I be just scripting the DNS name up separately?

In the alias target section can you try using Canonical Hosted Zone ID. Do you already have the following in the ebextension or am I missing something.

"HostedZoneId" : { "Fn::GetAtt" : ["AWSEBLoadBalancer","CanonicalHostedZoneNameID"] }

Realised I was going to the wrong way putting an environment specific resource into ebextensions (plus a bunch of other things wrong with the snippet in the question mean it would never work).

This is what I ended up with that works for my use case. This way I get a unique URL per environment, based on the environment name (different, readable and obbviously named urls for integration, uat and production environments).

Resources: {
  "dnsResourceNname" : {
    "Type" : "AWS::Route53::RecordSet",
    "Properties" : {
      "HostedZoneName" : "mydomain.com.",
      "Comment" : "DNS name for envornment ELB.",
      "Name" : {
        "Fn::Join" : [ "", [
          { "Ref" : "AWSEBEnvironmentName" },
          ".mydomain.com."
        ] ]
      },
      "Type" : "CNAME",
      "TTL" : "900",
      "ResourceRecords" : [ { "Fn::GetAtt" : ["AWSEBLoadBalancer","DNSName"] } ]
    }
  }

}
