type property
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
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 of
RoutingPolicy
.
-
You can't specify both
CNAME
for Type
and settings
for HealthCheckConfig
. If you do, the request will fail with an
InvalidInput
error.
SRV
Route 53 returns the value for an SRV
record. The value for an
SRV
record uses the following values:
priority weight port service-hostname
Note the following about the values:
-
The values of
priority
and weight
are both set to
1
and can't be changed.
-
The value of
port
comes from the value that you specify for the
AWS_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
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, note the following:
-
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.
-
If you're using a system that requires a specific
SRV
format,
such as HAProxy, see the Name
element in the documentation about CreateService
for
information about how to specify the correct name format.
