Consul on Kubernetes now supports the `Registration` CRD to register services running on external nodes without a terminating gateway. We recommend registering services with this CRD instead of deploying a terminating gateway. For more information, refer to [Register services running on external nodes to Consul on Kubernetes](/consul/docs/k8s/deployment-configurations/external-service).

The process to register an external service in Consul on Kubernetes consists of the following steps:
1. [Start Consul ESM](/consul/tutorials/connect-services/service-registration-external-services#monitor-the-external-service-with-consul-esm). You must use Consul ESM to run health checks on external services.
1. Define the external service and its health checks in a [`Registration` CRD](/consul/docs/connect/config-entries/registration).
1. Apply the CRD to your Kubernetes cluster. Internally, this action triggers an API call to Consul's [`/catalog/register` endpoint](/consul/api-docs/catalog#register-entity) to register the service.
1. When using Consul's service mesh, define [service intentions](/consul/docs/connect/intentions) between the external service and services it communicates with.
