      Description

      As today we have a ServiceCall EIP that makes it easy to call external services in a cloud environment leveraging external service registry such as kubernetes, consul, etcd, spring-cloud & co so It could make sense to add a way for a route to register itself in such registries and be available as a service for other to consume.

      Something like:

          // programmatic config
          from("jetty:http://0.0.0.0:8001/service1")
              .serviceRegistry()
                  .name("service-1")
                  .host("....")
                  .port(8001)
                  .meta("camel.protocol", "http")
                  .meta("camel.component", "jetty")
                  .meta("camel.context.path", "/service1")
                  .end()
              .to("direct:service-1")
      
          // Inherit from a global config and eventually override it
          from("jetty:http://0.0.0.0:8002/service2")
            .serviceRegistry("service-2")
                .configRef("service-registry-conf")
                .port(8002)
            .to("direct:service-2")
      
          // Smart auto configuration
          //   i.e. if the endpoint implements DiscoverableService
          from("jetty:http://0.0.0.0:8003/service3")
            .serviceRegistry("service-3")
            .to("direct:service-3")
      

      Beside making camel play better in cloud environment, you can use the service call to connect camel based micro services with minimal configuration as the registration may provide some additional meta data that the service call can use for auto-configuration (of course not all the registries can do it).

      The future Health API/Service may then also be configured to remove or invalidate the service if the route is reported as not healthy.
