Properties

cidrRoutingConfigCidrRoutingConfigcidr_routing_configCidrRoutingConfigcidrRoutingConfigCidrRoutingConfigCidrRoutingConfigCidrRoutingConfigCidrRoutingConfigCidrRoutingConfig#

The object that is specified in resource record set object when you are linking a resource record set to a CIDR location.

Default: No CIDR routing configured

A LocationName with an asterisk “*” can be used to create a default CIDR record. CollectionId is still required for default record.

commentstringcommentstrcommentStringCommentstringComment*string#

A comment to add on the record.

Default: no comment

deleteExistingbooleandelete_existingbooldeleteExistingBooleanDeleteExistingboolDeleteExisting*bool= falsedeprecated#

This property is dangerous and can lead to unintended record deletion in case of deployment failure.

notes

This allows you to deploy a new record set while minimizing the downtime because the new record set will be created immediately after the existing one is deleted. It also avoids "manual" actions to delete existing record sets.

N.B.: this feature is dangerous, use with caution! It can only be used safely when deleteExisting is set to true as soon as the resource is added to the stack. Changing an existing Record Set's deleteExisting property from false -> true after deployment will delete the record!

failoverFailoverfailoverFailoverfailoverFailoverFailoverFailoverFailoverFailover#

Failover configuration for the record set.

Default: No failover configuration

notes

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.

You must also include the HealthCheckId element for PRIMARY configurations.

geoLocationGeoLocationgeo_locationGeoLocationgeoLocationGeoLocationGeoLocationGeoLocationGeoLocationGeoLocation#

The geographical origin for this record to return DNS records based on the user's location.

healthCheckIHealthCheckhealth_checkIHealthCheckhealthCheckIHealthCheckHealthCheckIHealthCheckHealthCheckIHealthCheck#

The health check to associate with the record set.

Default: No health check configured

Route53 will return this record set in response to DNS queries only if the health check is passing.

multiValueAnswerbooleanmulti_value_answerboolmultiValueAnswerBooleanMultiValueAnswerboolMultiValueAnswer*bool= false#

Whether to return multiple values, such as IP addresses for your web servers, in response to DNS queries.

recordNamestringrecord_namestrrecordNameStringRecordNamestringRecordName*string#

The subdomain name for this record. This should be relative to the zone root name.

Default: zone root

For example, if you want to create a record for acme.example.com, specify "acme".

You can also specify the fully qualified domain name which terminates with a ".". For example, "acme.example.com.".

regionstringregionstrregionStringRegionstringRegion*string#

The Amazon EC2 Region where you created the resource that this resource record set refers to.

Default: Do not set latency based routing

notes

The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.

When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Route 53 then returns the value that is associated with the selected resource record set.

setIdentifierstringset_identifierstrsetIdentifierStringSetIdentifierstringSetIdentifier*string#

A string used to distinguish between different records with the same combination of DNS name and type.

Default: Auto generated string

It can only be set when either weight or geoLocation is defined.

This parameter must be between 1 and 128 characters in length.

ttlDurationttlDurationttlDurationTtlDurationTtlDuration= Duration.minutes(30)#

The resource record cache time to live (TTL).

weightnumberweightint | floatweightNumberWeightdoubleWeight*float64#

Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set.

Default: Do not set weighted routing

notes

Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Route 53 then responds to queries based on the ratio of a resource's weight to the total.

This value can be a number between 0 and 255.

zoneIHostedZonezoneIHostedZonezoneIHostedZoneZoneIHostedZoneZoneIHostedZonerequired#

The hosted zone in which to define the new record.
