Routes collision in ConductR

[markusjura]

Having a Lagom Descriptor called user and another service that is using the /user route is not possible.

Under ConductR, each Lagom service is accessible under http://:9000/DESCRIPTOR_NAME where DESCRIPTOR_NAME is the name of the Descriptor: https://github.com/lagom/online-auction-java/blob/master/user-api/src/main/java/com/example/auction/user/api/UserService.java#L25

This suffix is necessary so that every service can use the same port 9000.

So you either rename the Descriptor name of the user-api service or the route of webGateway.

Exactly what I did. ;-)

Thanks for the detailed explanation!

@markusjura why is http://:9000/user even published in the service gateway if that's a private API? I would expect user -> [<list of (ip/port)] to exist in a Service Registry that's only consumable from the private network.

What is the motivation to expose the list of services in http://:9000/<service-name> ?

Yeah, what does http://:9000/user even route to? Shouldn't only ACLs declared by the service descriptor be exposed?

@markusjura does this question still apply? If so, can we find some docs on the subject? /cc @TimMoore

[markusjura]

@ignasi35 Yes, it still applies. I would need to dive a bit deeper into that again to gain a full understanding. Will not be able to do that today. Hopefully, beginning of next week. I keep you posted.

Run "cf unmap-route YOUR-APP-NAME OLD-ROUTE" to remove the existing route from that app.

$ cf env my-app

@anii1234 I think you might be in the wrong place 😄

[ignasi35]

This is solved. user-service no longer collisions with web-gateway
