Constructor Details

#initialize(options = {}) ⇒ Real

Initialize connection to Route 53 DNS service

Notes

options parameter must include values for :aws_access_key_id and :aws_secret_access_key in order to create a connection

Examples

dns = Fog::AWS::DNS.new(
  :aws_access_key_id => your_aws_access_key_id,
  :aws_secret_access_key => your_aws_secret_access_key
)

Parameters

  • options<~Hash> - config arguments for connection. Defaults to {}.

Returns

#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

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

      • set_identifier<~String> - An identifier that differentiates among multiple resource record sets that have the same combination of DNS name and type.

      • region<~String> - The Amazon EC2 region where the resource that is specified in this resource record set resides. (Latency only)

      • failover<~String> - To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover; for the other resource record set, you specify SECONDARY.

      • geo_location<~String XML> - A complex type currently requiring XML that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query.

      • health_check_id<~String> - If you want Amazon Route 53 to return this resource record set in response to a DNS query only when a health check is passing, include the HealthCheckId element and specify the ID of the applicable health check.

      • 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
