#dns_records ⇒ Array<Types::DnsRecord>

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.

The record type of a service specified in a ‘DnsRecord` object can’t be updated. To change a record type, you need to delete the service and recreate it with a new ‘DnsConfig`.

#routing_policy ⇒ 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 markdown=“1”> If you want to use this service to register instances that create alias records, specify ‘WEIGHTED` for the routing policy.

</note>

You can specify the following values:

MULTIVALUE

: If you define a health check for the service and the health check

is healthy, Route

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
