UpdateService - AWS Cloud Map


Submits a request to perform the following operations:

  • Update the TTL setting for existing DnsRecords configurations

  • Add, update, or delete HealthCheckConfig for a specified service


    You can't add, update, or delete a HealthCheckCustomConfig configuration.

For public and private DNS namespaces, note the following:

  • If you omit any existing DnsRecords or HealthCheckConfig configurations from an UpdateService request, the configurations are deleted from the service.

  • If you omit an existing HealthCheckCustomConfig configuration from an UpdateService request, the configuration isn't deleted from the service.

When you update settings for a service, AWS Cloud Map also updates the corresponding settings in all the records and health checks that were created by using the specified service.
