CfnService.DnsRecordProperty.getTtl()
ttl
- The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record. This parameter is required.
Alias records don't include a TTL because RouteĀ 53 uses the TTL for the AWS resource that an alias record routes traffic to. If you include the
AWS_ALIAS_DNS_NAME
attribute when you submit a RegisterInstance request, theTTL
value is ignored. Always specify a TTL for the service; you can use a service to register instances that create either alias or non-alias records.

public CfnService.DnsRecordProperty.Builder type(java.lang.String type)
CfnService.DnsRecordProperty.getType()
type
- The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries. This parameter is required.
You can specify values for Type
in the following combinations:
A
AAAA
A
and AAAA
SRV
CNAME
If you want AWS Cloud Map to create a Route 53 alias record when you register an instance, specify A
or AAAA
for Type
.
You specify other settings, such as the IP address for A
and AAAA
records, when you register an instance. For more information, see RegisterInstance .
The following values are supported:
WEIGHTED
for the value of RoutingPolicy
.CNAME
for Type
and settings for HealthCheckConfig
. If you do, the request will fail with an InvalidInput
error.SRV
record. The value for an SRV
record uses the following values:
priority weight port service-hostname
Note the following about the values:
priority
and weight
are both set to 1
and can't be changed.port
comes from the value that you specify for the AWS_INSTANCE_PORT
attribute when you submit a RegisterInstance request.service-hostname
is a concatenation of the following values:InstanceId
when you register an instance.
For example, if the value of InstanceId
is test
, the name of the service is backend
, and the name of the namespace is example.com
, the value of service-hostname
is:
test.backend.example.com
If you specify settings for an SRV
record and if you specify values for AWS_INSTANCE_IPV4
, AWS_INSTANCE_IPV6
, or both in the RegisterInstance
request, AWS Cloud Map automatically creates A
and/or AAAA
records that have the same name as the value of service-hostname
in the SRV
record. You can ignore these records.
