Service Discovery - am i missing something

Rancher
1

Hi
I have added a RabbitMQ container directly in Rancher using the workload UI, which should create the associated DNS records (Service Discovery)

I add rabbit, with the name of “queue” in the “data” namespace. expose a ClusterIP port of 5672 (and 15672)

now i try to connect to it via my service (which i deploy in another namespace, called basket). i set the connection to be “queue.data”, this does not work.

I have also deployed the application in the same basket app into the data namespace, and set the connection to queue. this does not work either.

the error from the app is

RabbitMQ Connect Failed: Broker unreachable: guest@queue:5672/

i have deployed the rabbit as a stateful and scale-able container, no dice.

here is the rabbit setup (i know that the 15672 port is not required)
