Overview
Constructs a service interface object. Each API operation is exposed as a function on service.
Service Description
With Cloud Map, you can configure public DNS, private DNS, or HTTP namespaces that your microservice applications run in. When an instance becomes available, you can call the Cloud Map API to register the instance with Cloud Map. For public or private DNS namespaces, Cloud Map automatically creates DNS records and an optional health check. Clients that submit public or private DNS queries, or HTTP requests, for the service receive an answer that contains up to eight healthy records.
Sending a Request Using ServiceDiscovery
var servicediscovery = new AWS.ServiceDiscovery();
servicediscovery.createHttpNamespace(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Locking the API Version
In order to ensure that the ServiceDiscovery object uses this specific API, you can
construct the object by passing the apiVersion
option to the constructor:
var servicediscovery = new AWS.ServiceDiscovery({apiVersion: '2017-03-14'});
You can also set the API version globally in AWS.config.apiVersions
using
the servicediscovery service identifier:
AWS.config.apiVersions = {
servicediscovery: '2017-03-14',
// other service API versions
};
var servicediscovery = new AWS.ServiceDiscovery();

Parameters:
-
params
(Object)
(defaults to: {})
—
Name
— (String
)The name that you want to assign to the service.
Note: Do not include sensitive information in the name if the namespace is discoverable by public DNS queries.If you want Cloud Map to create an
SRV
record when you register an instance and you're using a system that requires a specificSRV
format, such as HAProxy, specify the following forName
:-
Start the name with an underscore (), such as
_exampleservice
. -
End the name with .protocol, such as
._tcp
.
When you register an instance, Cloud Map creates an
SRV
record and assigns a name to the record by concatenating the service name and the namespace name (for example,_exampleservice._tcp.example.com
).Note: For services that are accessible by DNS queries, you can't create multiple services with names that differ only by case (such as EXAMPLE and example). Otherwise, these services have the same DNS name and can't be distinguished. However, if you use a namespace that's only accessible by API calls, then you can create services that with names that differ only by case.-
NamespaceId
— (String
)The ID of the namespace that you want to use to create the service. The namespace ID must be specified, but it can be specified either here or in the
DnsConfig
object.CreatorRequestId
— (String
)A unique string that identifies the request and that allows failed
If a token is not provided, the SDK will use a version 4 UUID.CreateService
requests to be retried without the risk of running the operation twice.CreatorRequestId
can be any unique string (for example, a date/timestamp).Description
— (String
)A description for the service.
DnsConfig
— (map
)A complex type that contains information about the Amazon Route 53 records that you want Cloud Map to create when you register an instance.

The ID of the namespace to use for DNS configuration.
RoutingPolicy
— (String
)The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service.
Note: If you want to use this service to register instances that create alias records, specifyWEIGHTED
for the routing policy.You can specify the following values:
- MULTIVALUE
-
If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances.
For example, suppose that the service includes configurations for one
A
record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with IP addresses for up to eight healthy instances. If fewer than eight instances are healthy, Route 53 responds to every DNS query with the IP addresses for all of the healthy instances.If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the values for up to eight instances.
For more information about the multivalue routing policy, see Multivalue Answer Routing in the Route 53 Developer Guide.
- WEIGHTED
-
Route 53 returns the applicable value from one randomly selected instance from among the instances that you registered using the same service. Currently, all records have the same weight, so you can't route more or less traffic to any instances.
For example, suppose that the service includes configurations for one
A
record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with the IP address for one randomly selected instance from among the healthy instances. If no instances are healthy, Route 53 responds to DNS queries as if all of the instances were healthy.If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the applicable value for one randomly selected instance.

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
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 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
— required — (Integer
)The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record.
Note: 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 theAWS_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.
HealthCheckConfig
— (map
)Public DNS and HTTP namespaces only. A complex type that contains settings for an optional Route 53 health check. If you specify settings for a health check, Cloud Map associates the health check with all the Route 53 DNS records that you specify in

.If you specify a health check configuration, you can specify either
HealthCheckCustomConfig
orHealthCheckConfig
but not both.For information about the charges for health checks, see Cloud Map Pricing.
Type
— required — (String
)The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy.
You can't change the value of
Type
after you create a health check.You can create the following types of health checks:
-
HTTP: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400.
-
HTTPS: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400.
If you specify HTTPS for the value of
Type
, the endpoint must support TLS v1.0 or later. -
TCP: Route 53 tries to establish a TCP connection.
If you specify
TCP
forType
, don't specify a value forResourcePath

but not both.You can't add, update, or delete a
HealthCheckCustomConfig
configuration from an existing service.FailureThreshold
— (Integer
)This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an
UpdateInstanceCustomHealthStatus
request before changing the status of the service instance.The number of 30-second intervals that you want Cloud Map to wait after receiving an
UpdateInstanceCustomHealthStatus
request before it changes the health status of a service instance.Sending a second or subsequent
UpdateInstanceCustomHealthStatus
request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits30
seconds after the first request to make the change.
Tags

Id
— required — (String
)An identifier that you want to associate with the instance. Note the following:
-
If the service that's specified by
ServiceId
includes settings for anSRV
record, the value ofInstanceId
is automatically included as part of the value for theSRV
record. For more information, see DnsRecord > Type. -
You can use this value to update an existing instance.
-
To register a new instance, you must specify a value that's unique among instances that you register by using the same service.
-
If you specify an existing
InstanceId
andServiceId
, Cloud Map updates the existing DNS records. If there's also an existing health check, Cloud Map deletes the old health check and creates a new one.Note: The health check isn't deleted immediately, so it will still appear for a while if you submit aListHealthChecks
request, for example.
-
CreatorRequestId
— (String
)A unique string that identifies the request and that allows failed
RegisterInstance
requests to be retried without the risk of executing the operation twice. You must use a uniqueCreatorRequestId
string every time you submit aRegisterInstance
request if you're registering additional instances for the same namespace and service.CreatorRequestId
can be any unique string (for example, a date/time stamp).Attributes
— (map<String>
)A string map that contains the following information for the service that you specify in
ServiceId
:-
The attributes that apply to the records that are defined in the service.
-
For each attribute, the applicable value.
Note: Do not include sensitive information in the attributes if the namespace is discoverable by public DNS queries.Supported attribute keys include the following:
- AWS_ALIAS_DNS_NAME
-
If you want Cloud Map to create a Route 53 alias record that routes traffic to an Elastic Load Balancing load balancer, specify the DNS name that's associated with the load balancer. For information about how to get the DNS name, see AliasTarget->DNSName in the Route 53 API Reference.
Note the following:
-
The configuration for the service that's specified by
ServiceId
must include settings for anA
record, anAAAA
record, or both. -
In the service that's specified by
ServiceId
, the value ofRoutingPolicy
must beWEIGHTED
. -
If the service that's specified by
ServiceId
includesHealthCheckConfig
settings, Cloud Map creates the health check, but it won't associate the health check with the alias record. -
Auto naming currently doesn't support creating alias records that route traffic to Amazon Web Services resources other than ELB load balancers.
-
If you specify a value for
AWS_ALIAS_DNS_NAME
, don't specify values for any of theAWS_INSTANCE
attributes.
-
- AWS_EC2_INSTANCE_ID
-
HTTP namespaces only. The Amazon EC2 instance ID for the instance. The
AWS_INSTANCE_IPV4
attribute contains the primary private IPv4 address. - AWS_INIT_HEALTH_STATUS
-
If the service configuration includes
HealthCheckCustomConfig
, you can optionally useAWS_INIT_HEALTH_STATUS
to specify the initial status of the custom health check,HEALTHY
orUNHEALTHY
. If you don't specify a value forAWS_INIT_HEALTH_STATUS
, the initial status isHEALTHY
. - AWS_INSTANCE_CNAME
-
If the service configuration includes a
CNAME
record, the domain name that you want Route 53 to return in response to DNS queries (for example,example.com
).This value is required if the service specified by
ServiceId
includes settings for anCNAME
record. - AWS_INSTANCE_IPV4
-
If the service configuration includes an
A
record, the IPv4 address that you want Route 53 to return in response to DNS queries (for example,192.0.2.44
).This value is required if the service specified by
ServiceId
includes settings for anA
record. If the service includes settings for anSRV
record, you must specify a value forAWS_INSTANCE_IPV4
,AWS_INSTANCE_IPV6
, or both. - AWS_INSTANCE_IPV6
-
If the service configuration includes an
AAAA
record, the IPv6 address that you want Route 53 to return in response to DNS queries (for example,2001:0db8:85a3:0000:0000:abcd:0001:2345
).This value is required if the service specified by
ServiceId
includes settings for anAAAA
record. If the service includes settings for anSRV
record, you must specify a value forAWS_INSTANCE_IPV4
,AWS_INSTANCE_IPV6
, or both. - AWS_INSTANCE_PORT
-
If the service includes an
SRV
record, the value that you want Route 53 to return for the port.If the service includes
HealthCheckConfig
, the port on the endpoint that you want Route 53 to send requests to.This value is required if you specified settings for an
SRV
record or a Route 53 health check when you created the service.

DnsConfig
— (map
)A complex type that contains information about the Route 53 DNS records that you want Cloud Map to create when you register an instance.
The record types of a service can only be changed by deleting the service and recreating it with a new
Dnsconfig
.NamespaceId
— (String
)Use NamespaceId in Service instead.
The ID of the namespace to use for DNS configuration.
RoutingPolicy
— (String
)The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service.
Note: If you want to use this service to register instances that create alias records, specifyWEIGHTED
for the routing policy.You can specify the following values:
- MULTIVALUE
-
If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances.
For example, suppose that the service includes configurations for one
A
record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with IP addresses for up to eight healthy instances. If fewer than eight instances are healthy, Route 53 responds to every DNS query with the IP addresses for all of the healthy instances.If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the values for up to eight instances.
For more information about the multivalue routing policy, see Multivalue Answer Routing in the Route 53 Developer Guide.
- WEIGHTED
-
Route 53 returns the applicable value from one randomly selected instance from among the instances that you registered using the same service. Currently, all records have the same weight, so you can't route more or less traffic to any instances.
For example, suppose that the service includes configurations for one
A
record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with the IP address for one randomly selected instance from among the healthy instances. If no instances are healthy, Route 53 responds to DNS queries as if all of the instances were healthy.If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the applicable value for one randomly selected instance.
For more information about the weighted routing policy, see Weighted Routing in the Route 53 Developer Guide.
"MULTIVALUE"
"WEIGHTED"
DnsRecords
— required — (Array<map>
)An array that contains one
DnsRecord
object for each Route 53 DNS record that you want Cloud Map to create when you register an instance.Type
— required — (String
)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
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 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.
-
"SRV"
"A"
"AAAA"
"CNAME"
-
TTL
— required — (Integer
)The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record.
Note: 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 theAWS_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.
Type
— (String
)Describes the systems that can be used to discover the service instances.
- DNS_HTTP
-
The service instances can be discovered using either DNS queries or the
DiscoverInstances
API operation. - HTTP
-
The service instances can only be discovered using the
DiscoverInstances
API operation. - DNS
-
Reserved.

HealthCheckConfig
— (map
)Public DNS and HTTP namespaces only. A complex type that contains settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in
DnsConfig
.For information about the charges for health checks, see Amazon Route 53 Pricing.
Type
— required — (String
)The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy.
You can't change the value of
Type
after you create a health check.You can create the following types of health checks:
-
HTTP: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400.
-
HTTPS: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400.
If you specify HTTPS for the value of
Type
, the endpoint must support TLS v1.0 or later. -
TCP: Route 53 tries to establish a TCP connection.
If you specify
TCP
forType
, don't specify a value forResourcePath
.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide.
Possible values include:"HTTP"
"HTTPS"
"TCP"
-
ResourcePath
— (String
)The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is
/docs/route53-health-check.html
. Route 53 automatically adds the DNS name for the service. If you don't specify a value forResourcePath
, the default value is/
.If you specify
TCP
forType
, you must not specify a value forResourcePath
.FailureThreshold
— (Integer
)The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide.
HealthCheckCustomConfig
— (map
)A complex type that contains information about an optional custom health check.
If you specify a health check configuration, you can specify either
HealthCheckCustomConfig
orHealthCheckConfig
but not both.FailureThreshold
— (Integer
)This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an
UpdateInstanceCustomHealthStatus
request before changing the status of the service instance.The number of 30-second intervals that you want Cloud Map to wait after receiving an
UpdateInstanceCustomHealthStatus
request before it changes the health status of a service instance.Sending a second or subsequent
UpdateInstanceCustomHealthStatus
request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits30
seconds after the first request to make the change.
CreateDate
— (Date
)The date and time that the service was created, in Unix format and Coordinated Universal Time (UTC). The value of
CreateDate
is accurate to milliseconds. For example, the value1516925490.087
represents Friday, January 26, 2018 12:11:30.087 AM.CreatorRequestId
— (String
)A unique string that identifies the request and that allows failed requests to be retried without the risk of running the operation twice.
CreatorRequestId
can be any unique string (for example, a date/timestamp).

Description
— (String
)The description that you specify when you create the service.
InstanceCount
— (Integer
)The number of instances that are currently associated with the service. Instances that were previously associated with the service but that are deleted aren't included in the count. The count might not reflect pending registrations and deregistrations.
DnsConfig
— (map
)Information about the Route 53 DNS records that you want Cloud Map to create when you register an instance.
NamespaceId
— (String
)Use NamespaceId in Service instead.
The ID of the namespace to use for DNS configuration.
RoutingPolicy
— (String
)The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service.
Note: If you want to use this service to register instances that create alias records, specifyWEIGHTED
for the routing policy.You can specify the following values:
- MULTIVALUE
-
If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances.
For example, suppose that the service includes configurations for one
A
record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with IP addresses for up to eight healthy instances. If fewer than eight instances are healthy, Route 53 responds to every DNS query with the IP addresses for all of the healthy instances.If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the values for up to eight instances.
For more information about the multivalue routing policy, see Multivalue Answer Routing in the Route 53 Developer Guide.
- WEIGHTED
-
Route 53 returns the applicable value from one randomly selected instance from among the instances that you registered using the same service. Currently, all records have the same weight, so you can't route more or less traffic to any instances.
For example, suppose that the service includes configurations for one
A
record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with the IP address for one randomly selected instance from among the healthy instances. If no instances are healthy, Route 53 responds to DNS queries as if all of the instances were healthy.If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the applicable value for one randomly selected instance.
For more information about the weighted routing policy, see Weighted Routing in the Route 53 Developer Guide.

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 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.
-
"SRV"
"A"
"AAAA"
"CNAME"
-
TTL
— required — (Integer
)The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record.
Note: 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 theAWS_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.
HealthCheckConfig
— (map
)Public DNS and HTTP namespaces only. Settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in
DnsConfig
.Type
— required — (String
)The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy.
You can't change the value of
Type
after you create a health check.You can create the following types of health checks:
-
HTTP: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400.
-
HTTPS: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400.
If you specify HTTPS for the value of
Type
, the endpoint must support TLS v1.0 or later. -
TCP: Route 53 tries to establish a TCP connection.
If you specify
TCP
forType
, don't specify a value forResourcePath
.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide.
Possible values include:"HTTP"
"HTTPS"
"TCP"
-
ResourcePath
— (String
)The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is
/docs/route53-health-check.html
. Route 53 automatically adds the DNS name for the service. If you don't specify a value forResourcePath
, the default value is/
.If you specify
TCP
forType
, you must not specify a value forResourcePath
.FailureThreshold
— (Integer
)The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide.
HealthCheckCustomConfig
— (map
)Information about an optional custom health check. A custom health check, which requires that you use a third-party health checker to evaluate the health of your resources, is useful in the following circumstances:
-
You can't use a health check that's defined by
HealthCheckConfig
because the resource isn't available over the internet. For example, you can use a custom health check when the instance is in an Amazon VPC. (To check the health of resources in a VPC, the health checker must also be in the VPC.) -
You want to use a third-party health checker regardless of where your resources are located.
If you specify a health check configuration, you can specify either
HealthCheckCustomConfig
orHealthCheckConfig
but not both.FailureThreshold
— (Integer
)This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an
UpdateInstanceCustomHealthStatus
request before changing the status of the service instance.The number of 30-second intervals that you want Cloud Map to wait after receiving an
UpdateInstanceCustomHealthStatus
request before it changes the health status of a service instance.Sending a second or subsequent
UpdateInstanceCustomHealthStatus
request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits30
seconds after the first request to make the change.
-
CreateDate
— (Date
)The date and time that the service was created.
NextToken
— (String
)If the response contains
NextToken
, submit anotherListServices
request to get the next group of results. Specify the value ofNextToken
from the previous response in the next request.Note: Cloud Map getsMaxResults
services and then filters them based on the specified criteria. It's possible that no services in the firstMaxResults
services matched the specified criteria but that subsequent groups ofMaxResults
services do contain services that match the criteria.
-

registerInstance(params = {}, callback) ⇒ AWS.Request
Creates or updates one or more records and, optionally, creates a health check based on the settings in a specified service. When you submit a
RegisterInstance
request, the following occurs:-
For each DNS record that you define in the service that's specified by
ServiceId
, a record is created or updated in the hosted zone that's associated with the corresponding namespace. -
If the service includes
HealthCheckConfig
, a health check is created based on the settings in the health check configuration. -
The health check, if any, is associated with each of the new or updated records.
One
RegisterInstance
request must complete before you can submit another request and specify the same service ID and instance ID.For more information, see CreateService.
When Cloud Map receives a DNS query for the specified DNS name, it returns the applicable value:
-
If the health check is healthy: returns all the records
-
If the health check is unhealthy: returns the applicable value for the last healthy instance
-
If you didn't specify a health check configuration: returns all the records
For the current quota on the number of instances that you can register using the same namespace and using the same service, see Cloud Map quotas in the Cloud Map Developer Guide.

Parameters:
-
params
(Object)
(defaults to: {})
—
ServiceId
— (String
)The ID of the service that you want to use for settings for the instance.
InstanceId
— (String
)An identifier that you want to associate with the instance. Note the following:
-
If the service that's specified by
ServiceId
includes settings for anSRV
record, the value ofInstanceId
is automatically included as part of the value for theSRV
record. For more information, see DnsRecord > Type. -
You can use this value to update an existing instance.
-
To register a new instance, you must specify a value that's unique among instances that you register by using the same service.
-
If you specify an existing
InstanceId
andServiceId
, Cloud Map updates the existing DNS records, if any. If there's also an existing health check, Cloud Map deletes the old health check and creates a new one.Note: The health check isn't deleted immediately, so it will still appear for a while if you submit aListHealthChecks
request, for example.
Note: Do not include sensitive information inInstanceId
if the namespace is discoverable by public DNS queries and anyType
member ofDnsRecord
for the service containsSRV
because theInstanceId
is discoverable by public DNS queries.-
CreatorRequestId
— (String
)A unique string that identifies the request and that allows failed
If a token is not provided, the SDK will use a version 4 UUID.RegisterInstance
requests to be retried without the risk of executing the operation twice. You must use a uniqueCreatorRequestId
string every time you submit aRegisterInstance
request if you're registering additional instances for the same namespace and service.CreatorRequestId
can be any unique string (for example, a date/time stamp).Attributes
— (map<String>
)A string map that contains the following information for the service that you specify in
ServiceId
:-
The attributes that apply to the records that are defined in the service.
-
For each attribute, the applicable value.
Do not include sensitive information in the attributes if the namespace is discoverable by public DNS queries.
The following are the supported attribute keys.
- AWS_ALIAS_DNS_NAME
-
If you want Cloud Map to create an Amazon Route 53 alias record that routes traffic to an Elastic Load Balancing load balancer, specify the DNS name that's associated with the load balancer. For information about how to get the DNS name, see "DNSName" in the topic AliasTarget in the Route 53 API Reference.
Note the following:
-
The configuration for the service that's specified by
ServiceId
must include settings for anA
record, anAAAA
record, or both. -
In the service that's specified by
ServiceId
, the value ofRoutingPolicy
must beWEIGHTED
. -
If the service that's specified by
ServiceId
includesHealthCheckConfig
settings, Cloud Map will create the Route 53 health check, but it doesn't associate the health check with the alias record. -
Cloud Map currently doesn't support creating alias records that route traffic to Amazon Web Services resources other than Elastic Load Balancing load balancers.
-
If you specify a value for
AWS_ALIAS_DNS_NAME
, don't specify values for any of theAWS_INSTANCE
attributes. -
The
AWS_ALIAS_DNS_NAME
is not supported in the GovCloud (US) Regions.

, you can optionally useAWS_INIT_HEALTH_STATUS
to specify the initial status of the custom health check,HEALTHY
orUNHEALTHY
. If you don't specify a value forAWS_INIT_HEALTH_STATUS
, the initial status isHEALTHY
. - AWS_INSTANCE_CNAME
-
If the service configuration includes a
CNAME
record, the domain name that you want Route 53 to return in response to DNS queries (for example,example.com
).This value is required if the service specified by
ServiceId
includes settings for anCNAME
record. - AWS_INSTANCE_IPV4
-
If the service configuration includes an
A
record, the IPv4 address that you want Route 53 to return in response to DNS queries (for example,192.0.2.44
).This value is required if the service specified by

updateService(params = {}, callback) ⇒ AWS.Request
Submits a request to perform the following operations:
-
Update the TTL setting for existing
DnsRecords
configurations -
Add, update, or delete
HealthCheckConfig
for a specified serviceNote: You can't add, update, or delete aHealthCheckCustomConfig
configuration.
For public and private DNS namespaces, note the following:
-
If you omit any existing
DnsRecords
orHealthCheckConfig
configurations from anUpdateService
request, the configurations are deleted from the service. -
If you omit an existing
HealthCheckCustomConfig
configuration from anUpdateService
request, the configuration isn't deleted from the service.
When you update settings for a service, Cloud Map also updates the corresponding settings in all the records and health checks that were created by using the specified service.
Service Reference:
Examples:
UpdateService Example
/* This example submits a request to replace the DnsConfig and HealthCheckConfig settings of a specified service. */ var params = { Id: "srv-e4anhexample0004", Service: { DnsConfig: { DnsRecords: [ { TTL: 60, Type: "A" } ] }, HealthCheckConfig: { FailureThreshold: 2, ResourcePath: "/", Type: "HTTP" } } }; servicediscovery.updateService(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response /* data = { OperationId: "m35hsdrkxwjffm3xef4bxyy6vc3ewakx-jdn3y5g5" } */ });
Calling the updateService operation
var params = { Id: 'STRING_VALUE', /* required */ Service: { /* required */ Description: 'STRING_VALUE', DnsConfig: { DnsRecords: [ /* required */ { TTL: 'NUMBER_VALUE', /* required */ Type: SRV | A | AAAA | CNAME /* required */ }, /* more items */ ] }, HealthCheckConfig: { Type: HTTP | HTTPS | TCP, /* required */ FailureThreshold: 'NUMBER_VALUE', ResourcePath: 'STRING_VALUE' } } }; servicediscovery.updateService(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response });
Parameters:
-
params
(Object)
(defaults to: {})
—
Id
— (String
)The ID of the service that you want to update.
Service
— (map
)A complex type that contains the new settings for the service.
Description
— (String
)A description for the service.
DnsConfig
— (map
)Information about the Route 53 DNS records that you want Cloud Map to create when you register an instance.
DnsRecords
— required — (Array<map>
)An array that contains one
DnsRecord
object for each Route 53 record that you want Cloud Map to create when you register an instance.Type
— required — (String
)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
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 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.
-
"SRV"
"A"
"AAAA"
"CNAME"
-
TTL
— required — (Integer
)The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record.
Note: 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 theAWS_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.
HealthCheckConfig
— (map
)Public DNS and HTTP namespaces only. Settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in
DnsConfig
.Type
— required — (String
)The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy.
You can't change the value of
Type
after you create a health check.You can create the following types of health checks:
-
HTTP: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400.
-
HTTPS: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400.
If you specify HTTPS for the value of
Type
, the endpoint must support TLS v1.0 or later. -
TCP: Route 53 tries to establish a TCP connection.
If you specify
TCP
forType
, don't specify a value forResourcePath
.
For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide.
Possible values include:"HTTP"
"HTTPS"
"TCP"
-
ResourcePath
— (String
)The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is
/docs/route53-health-check.html
. Route 53 automatically adds the DNS name for the service. If you don't specify a value forResourcePath
, the default value is/
.If you specify
TCP
forType
, you must not specify a value forResourcePath
.FailureThreshold
— (Integer
)The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide.
