Description

When creating a new EC2 instance via the web console you have the option to choose the hostname type for the new instance - options are either IP name by default (ip-172-26-0-1.eu-west-3.compute.internal) or Resource name (i-0f0ccc1aa12371b73.eu-west-3.compute.internal). It should be possible to set this option in terraform.

API-wise it uses the PrivateDnsNameOptions struct:

                    "PrivateDnsNameOptions": {
                        "HostnameType": "resource-name",
                        "EnableResourceNameDnsARecord": true,
                        "EnableResourceNameDnsAAAARecord": false
                    }

New or Affected Resource(s)

Potential Terraform Configuration

  private_dns_name_options {
    hostname_type = "resource-name" | "ip-name"
  }
