Instance Method Details

#change_resource_record_sets(zone_id, change_batch, options = {}) ⇒ Object

Use this action to create or change your authoritative DNS information for a zone docs.amazonwebservices.com/Route53/latest/DeveloperGuide/RRSchanges.html#RRSchanges_API

Parameters

  • zone_id<~String> - ID of the zone these changes apply to

  • options<~Hash>

    • comment<~String> - Any comments you want to include about the change.

  • change_batch<~Array> - The information for a change request

    • changes<~Hash> -

      • action<~String> - ‘CREATE’ or ‘DELETE’

      • name<~String> - This must be a fully-specified name, ending with a final period

      • type<~String> - A | AAAA | CNAME | MX | NS | PTR | SOA | SPF | SRV | TXT

      • ttl<~Integer> - Time-to-live value - omit if using an alias record

      • resource_records<~Array> - Omit if using an alias record

      • alias_target<~Hash> - Information about the domain to which you are redirecting traffic (Alias record sets only)

        • dns_name<~String> - The Elastic Load Balancing domain to which you want to reroute traffic

        • hosted_zone_id<~String> - The ID of the hosted zone that contains the Elastic Load Balancing domain to which you want to reroute traffic

        • evaluate_target_health<~Boolean> - Applies only to alias, weighted alias, latency alias, and failover alias resource record sets: If you set the value of EvaluateTargetHealth to true, the alias resource record sets inherit the health of the referenced resource record sets.

Returns

  • response<~Excon::Response>:

    • body<~Hash>:

      • ‘ChangeInfo’<~Hash>

        • ‘Id’<~String> - The ID of the request

        • ‘SubmittedAt’<~String> - The date and time the change was made

    • status<~Integer> - 200 when successful

Examples

Example changing a CNAME record:

change_batch_options = [
  {
    :action => "DELETE",
    :name => "foo.example.com.",
    :type => "CNAME",
    :ttl => 3600,
    :resource_records => [ "baz.example.com." ]
  },
  {
