Need a way to pass parameters to the load tests

[rocketraman]

My test class starts up my application server for the load test. However, it starts up on a random port. I need a way to send this port to my k6 tests so that it can connect to the app.

It seems like environment variables would be the way to go here, and the TestContainers withEnv function would work great, but it doesn't seem to be exposed in the DSL.
