rabbitmq port mismatch when cloudfoundry rabbitmq service is deployed on non-standard port

[gpsmit]

Hi All,

We are experiencing an issue with the starter apps deployed on cloud foundry with SCDF
We have a cloud foundry instance that can expose rabbitmq services outside of cloudfoundry. When we deploy such an exposed rabbitmq service it will be assigned a random available port (non default 5671/5672) with TLS enabled.
All the vcap service variables are properly bound to the deployed apps, with the random port also visible in the stream starter environment variables
We are using the app imports from rabbitmq-maven-latest.

But, when we deploy the stream starter apps through SCDF, they do not pick up the random port (4101 in this deployment) instead trying the default TLS port 5671:

LOGS:
Attempting to connect to: [redacted:5671].

When we manually set spring.rabbitmq.port=4101 still nothing happens.

LOGS:
Attempting to connect to: [redacted:5671].

It seems the redacted url is resolved from the cloud foundry variables, but the port isnt.

When we manually set the spring.rabbitmq.addresses property to the rabbitmq-uri:port/vhost everything is back to normal, but the apps should be able to resolve it from the cloud foundry variables.

We opened a ticket with vmware but they are pointing to the stream starter apps.
We see this in all the starter apps that we tried so far (http/bridge/rabbit/log)

Hi @gpsmit ,

If this is still an issue for you can you send a dump of the CF VCAP properties (w/ any sensitive info redacted) so we can understand what is going into the apps?

Thanks
