RegisterInstanceRequest Class | AWS SDK for .NET V3

Container for the parameters to the RegisterInstance operation. 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.

Properties

Name	Type	Description
Attributes	System.Collections.Generic.Dictionary<System.String, System.String>	Gets and sets the property Attributes. 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 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.
CreatorRequestId	System.String	Gets and sets the property CreatorRequestId. 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).
InstanceId	System.String	Gets and sets the property InstanceId. 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`, 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. The health check isn't deleted immediately, so it will still appear for a while if you submit a `ListHealthChecks` request, for example. 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.
ServiceId	System.String	Gets and sets the property ServiceId. The ID of the service that you want to use for settings for the instance.

Examples

Example: Register Instance


var client = new AmazonServiceDiscoveryClient();
var response = client.RegisterInstance(new RegisterInstanceRequest 
{
    Attributes = new Dictionary<string, string> {
        { "AWS_INSTANCE_IPV4", "172.2.1.3" },
        { "AWS_INSTANCE_PORT", "808" }
    },
    CreatorRequestId = "7a48a98a-72e6-4849-bfa7-1a458e030d7b",
    InstanceId = "myservice-53",
    ServiceId = "srv-p5zdwlg5uvvzjita"
});

string operationId = response.OperationId;
