Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.servicediscovery.*;
 Object instanceAttributes;
 CfnInstance cfnInstance = CfnInstance.Builder.create(this, "MyCfnInstance")
         .instanceAttributes(instanceAttributes)
         .serviceId("serviceId")
         // the properties below are optional
         .instanceId("instanceId")

getInstanceAttributes

@Stability(value=Stable)
 @NotNull
public Object getInstanceAttributes()

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.

Supported attribute keys include the following:

• AWS_ALIAS_DNS_NAME - If you want AWS Cloud Map to create a Route 53 alias record that routes traffic to an Elastic Load Balancing load balancer, specify the DNS name that is 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 is specified by ServiceId must include settings for an A record, an AAAA record, or both.
• In the service that is specified by ServiceId , the value of RoutingPolicy must be WEIGHTED .
• If the service that is specified by ServiceId includes HealthCheckConfig settings, AWS Cloud Map will create 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 AWS resources other than ELB load balancers.
• If you specify a value for AWS_ALIAS_DNS_NAME , don't specify values for any of the AWS_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. When creating resources with a type of AWS::ServiceDiscovery::Instance , if the AWS_EC2_INSTANCE_ID attribute is specified, the only other attribute that can be specified is AWS_INIT_HEALTH_STATUS . After the resource has been created, the AWS_INSTANCE_IPV4 attribute contains the primary private IPv4 address.
• AWS_INIT_HEALTH_STATUS - If the service configuration includes HealthCheckCustomConfig , when creating resources with a type of AWS::ServiceDiscovery::Instance 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 . This attribute can only be used when creating resources and will not be seen on existing resources.
• 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.

getServiceId

@Stability(value=Stable)
 @NotNull
public String getServiceId()

The ID of the service that you want to use for settings for the instance.

setServiceId

@Stability(value=Stable)
public void setServiceId(@NotNull
                                                  String value)

The ID of the service that you want to use for settings for the instance.

getInstanceId

@Stability(value=Stable)
 @Nullable
public String getInstanceId()

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 > 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 , AWS Cloud Map updates the existing DNS records, if any. If there's also an existing health check, AWS Cloud Map deletes the old health check and creates a new one.

The health check isn't deleted immediately, so it will still appear for a while if you submit a ListHealthChecks request, for example.

setInstanceId

@Stability(value=Stable)
public void setInstanceId(@Nullable
                                                   String value)

• 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 > Type .
• You can use this value to update an existing instance.
