ttl
Sets the value ofCfnService.DnsRecordProperty.getTtl()
- Parameters:
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.- Returns:
this
-
type
Sets the value ofCfnService.DnsRecordProperty.getType()
- Parameters:
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 forType
in the following combinations:A
AAAA
A
andAAAA
SRV
CNAME
If you want AWS Cloud Map to create a Route 53 alias record when you register an instance, specify
A
orAAAA
forType
.You specify other settings, such as the IP address for
A
andAAAA
records, when you register an instance. For more information, see RegisterInstance .The following values are supported:
- A - Route 53 returns the IP address of the resource in IPv4 format, such as 192.0.2.44.
- AAAA - Route 53 returns the IP address of the resource in IPv6 format, such as 2001:0db8:85a3:0000:0000:abcd:0001:2345.
- CNAME - Route 53 returns the domain name of the resource, such as www.example.com. Note the following:
- You specify the domain name that you want to route traffic to when you register an instance. For more information, see Attributes in the topic RegisterInstance .
- You must specify
WEIGHTED
for the value ofRoutingPolicy
. - You can't specify both
CNAME
forType
and settings forHealthCheckConfig
. If you do, the request will fail with anInvalidInput
error. - SRV - Route 53 returns the value for an
SRV
record. The value for anSRV
record uses the following values:
priority weight port service-hostname
Note the following about the values:
- The values of
priority
andweight
are both set to1
and can't be changed. - The value of
port
comes from the value that you specify for theAWS_INSTANCE_PORT
attribute when you submit a RegisterInstance request. - The value of
service-hostname
is a concatenation of the following values: - The value that you specify for
InstanceId
when you register an instance. - The name of the service.
- The name of the namespace.
For example, if the value of
InstanceId
istest
, the name of the service isbackend
, and the name of the namespace isexample.com
, the value ofservice-hostname
is:test.backend.example.com
If you specify settings for an
SRV
record and if you specify values forAWS_INSTANCE_IPV4
,AWS_INSTANCE_IPV6
, or both in theRegisterInstance
request, AWS Cloud Map automatically createsA
and/orAAAA
records that have the same name as the value ofservice-hostname
in theSRV
record. You can ignore these records.- Returns:
