# ServiceRegistry
<a name="API_ServiceRegistry"></a>

The details for the service registry.

Each service may be associated with one service registry. Multiple service registries for each service are not supported.

When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.

 ** containerName **   <a name="ECS-Type-ServiceRegistry-containerName"></a>

If the task definition that your service task specifies uses the `awsvpc` network mode and a type SRV DNS record is used, you must specify either a `containerName` and `containerPort` combination or a `port` value. However, you can't specify both.
