Expand description
A complex type that contains information about the Route 53 DNS records that you want Cloud Map to create when you register an instance.

syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.type: Option<RecordType>
The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries. You can specify values for Type
in the following combinations:
-
A
-
AAAA
-
A
andAAAA
-
SRV
-
CNAME
If you want 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:
- 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 the following:test.backend.example.com
-
If you specify settings for an
SRV
record, note the following:-
If you specify values for
AWS_INSTANCE_IPV4
,AWS_INSTANCE_IPV6
, or both in theRegisterInstance
request, 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. -
If you're using a system that requires a specific
SRV
format, such as HAProxy, see the Name element in the documentation aboutCreateService
for information about how to specify the correct name format.
-
ttl: Option<i64>
The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record.
Alias records don't include a TTL because Route 53 uses the TTL for the Amazon Web Services resource that an alias record routes traffic to. If you include the AWS_ALIAS_DNS_NAME
attribute when you submit a RegisterInstance request, the TTL
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.
