Running Containerized Integration Tests In CI

[Tomnivore]

Hello,

This question might be too specifc, but I'm wondering if anyone has managed to successfully run containerized @QuarkusIntegration tests in a GitLab CI/CD pipeline. (Probably any CI tool will do).

I've recently played around with integration testing and after a lot of trial and error I managed to run the tests against a container locally.
The command I'm using is mvn clean verify -DskipITs=false -Dquarkus.container-image.build=true which builds the image and runs the tests against it.
The test is done with RestAssured and they make API calls to Quarkus REST endpoints. When I do run the same command in a pipeline it seems to build the image and run the container just fine. Then the test tries to do the API call to localhost:8081/some-path and gets CONNECTION REFUSED.

My gut feeling is that the calls should be made somewhere else than localhost but I'm at a loss to where and how.
