Examples
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
using Amazon.CDK.AWS.ServiceDiscovery;

Synopsis
Properties
DnsRecords | An array that contains one |
NamespaceId | The ID of the namespace to use for DNS configuration. |
RoutingPolicy | The routing policy that you want to apply to all Route 53 DNS records that AWS Cloud Map creates when you register an instance and specify this service. |
Properties
DnsRecords
An array that contains one DnsRecord
object for each Route 53 DNS record that you want AWS Cloud Map to create when you register an instance.
object DnsRecords { get; }
Property Value
System.Object
Remarks
NamespaceId
The ID of the namespace to use for DNS configuration.
virtual string NamespaceId { get; }
Property Value
System.String
Remarks
You must specify a value for NamespaceId
either for DnsConfig
or for the service properties . Don't specify a value in both places.
RoutingPolicy
The routing policy that you want to apply to all Route 53 DNS records that AWS Cloud Map creates when you register an instance and specify this service.
virtual string RoutingPolicy { get; }
Property Value
System.String
Remarks
If you want to use this service to register instances that create alias records, specify WEIGHTED
for the routing policy.
You can specify the following values:
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 .
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 .
