Instance Attribute Details

#attributes ⇒ Hash<String,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][1] in the *Route 53 API Reference*.

Note the following:

* The configuration for the service that's specified by
  `ServiceId` must include settings for an `A` record, an `AAAA`
  record, or both.

* In the service that's specified by `ServiceId`, the value of
  `RoutingPolicy` must be `WEIGHTED`.

* If the service that's specified by `ServiceId` includes
  `HealthCheckConfig` 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 the `AWS_INSTANCE` attributes.

* The `AWS_ALIAS_DNS_NAME` is not supported in the GovCloud (US)
  Regions.

AWS_EC2_INSTANCE_ID

: *HTTP namespaces only.* The Amazon EC2 instance ID for the

instance. If the `AWS_EC2_INSTANCE_ID` attribute is specified,
then the only other attribute that can be specified is
`AWS_INIT_HEALTH_STATUS`. When the `AWS_EC2_INSTANCE_ID` attribute
is specified, then the `AWS_INSTANCE_IPV4` attribute will be
filled out with the primary private IPv4 address.

AWS_INIT_HEALTH_STATUS

: If the service configuration includes ‘HealthCheckCustomConfig`,

you can optionally use `AWS_INIT_HEALTH_STATUS` to specify the
initial status of the custom health check, `HEALTHY` or
`UNHEALTHY`. If you don't specify a value for
`AWS_INIT_HEALTH_STATUS`, the initial status is `HEALTHY`.

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 an `CNAME` 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 an `A` record. If the service includes
settings for an `SRV` record, you must specify a value for
`AWS_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 an `AAAA` record. If the service includes
settings for an `SRV` record, you must specify a value for
`AWS_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.

Custom attributes

: You can add up to 30 custom attributes. For each key-value pair,

the maximum length of the attribute name is 255 characters, and
the maximum length of the attribute value is 1,024 characters. The
total size of all provided attributes (sum of all keys and values)
must not exceed 5,000 characters.

# File 'lib/aws-sdk-servicediscovery/types.rb', line 2623

class RegisterInstanceRequest < Struct.new(
  :service_id,
  :instance_id,
  :creator_request_id,
  :attributes)
  SENSITIVE = []
  include Aws::Structure
end

#creator_request_id ⇒ 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 unique `CreatorRequestId` string every time you submit a `RegisterInstance` 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).

**A suitable default value is auto-generated.** You should normally not need to pass this option.

Returns:

  • (String)

  :attributes)
  SENSITIVE = []
  include Aws::Structure
end

#instance_id ⇒ 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 an `SRV` record, the value of `InstanceId` is automatically included as part of the value for the `SRV` record. For more information, see [DnsRecord &gt; 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` and `ServiceId`, 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 markdown=“1”> The health check isn’t deleted immediately, so it will still appear for a while if you submit a ‘ListHealthChecks` request, for example.

    </note>

<note markdown=“1”> Do not include sensitive information in ‘InstanceId` if the namespace is discoverable by public DNS queries and any `Type` member of `DnsRecord` for the service contains `SRV` because the `InstanceId` is discoverable by public DNS queries.
