How to test api endpoint with pipeline and newman

Question

I am trying to test out API endpoints with postman's newman during our pipeline tests. I am able to build with docker-compose I am able to run a script that prints our the newman version I am using:

newman -v

4.4.0

But when I try and run a newman test with the following:

- docker run build_app:latest ci/run-newman-tests.sh

I get the following error:

connect ECONNREFUSED 127.0.0.1:8081

It seems like newman cannot reach my endpoint of 127.0.0.1:8081. Any help would be greatly appreciated.

@alanhardin where is the application under test running? Is it running inside the build_app:latest docker container, or is it running outside in the pipelines build container?

Does build_app:latest image just container the newman tool and testing scripts?
