Im currently experimenting with UDP sockets in zig. The System consists of a test sender and a test reciever, both of which work fine and build fine on the host and in the containers, but somehow one of the twi generated executables is not copied into it's container and thus exits immediately.
dev_gs-exchange-1 | exec /runtime: no such file or directory
dev_gs-test-1 | Reciever Started...
dev_gs-exchange-1 exited with code 1
The Dockerfiles are still very barebones so bear with me...

Ive been trying to output the contents of the containers before, and they both showed the executables in the root directory of the containers as it should be. I expected the 2 Containers to just fire up the executables and be done with it. The Test container works fine. just Exchange doesn't
I also updated docker and docker-compose to the latest versions as i was still running an old version.
