---------------------------------------
Summary: camel cloud: expose routes as a service
Key: CAMEL-10793
URL: https://issues.apache.org/jira/browse/CAMEL-10793
Project: Camel
Issue Type: New Feature
Components: camel-core
Reporter: Luca Burgazzoli
Fix For: 2.19.0
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 & co so It could maje 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:
{code:java}
// 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
from("jetty:http://0.0.0.0:8003/service3";)
.serviceRegistry("service-3")
.to("direct:service-3")
{code}
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.
