@Nezteb you’re correct - we are actually missing a standard main.kt file which would create and start the server, although it would be a single line of code - will add that file later. 🙃
However, the runnable environment file here is actually a development tool which not only starts up the main server, but also the fake dependency servers, all configured correctly to communicate. So whilst we could have that missing main file, it wouldn’t really be able to talk to anything since there are no "real" dependencies.
Maybe we can add a way to configure the env using docker-compose to show how the security server system would be started IRL
