How to configure Prometheus running on kubernetis to otel-collector -config file

[RSoodAMAT]

Hi ,

We are running Prometheus on Kubernetis cluster at 30090. It is a Node Port.
When i tried configuring the same with my local otel -collector config -demo file . I get the below exception

exporters:
prometheus:
endpoint: "k8s-m1:30090"
namespace: traincenter
const_labels:
label1: value1
logging:

Exception :

otel-collector_1 | Error: cannot setup pipelines: cannot start builtExporters: listen tcp 10.200.7.39:30090: bind: cannot assign requested address
otel-collector_1 | 2021/06/21 13:43:57 application run finished with error: cannot setup pipelines: cannot start builtExporters: listen tcp 10.200.7.39:30090: bind: cannot assign requested address

What is the issue .
Promethus is running on 9090 port with Node port being 30090.

I think this is a good question for the collector repository, rather than java. Please reach out on CNCF slack in the #otel-collector channel or the https://github.com/open-telemetry/opentelemetry-collector repository.
