Containers created and started by testcontainers-go through Docker Compose are not guaranteed to be cleaned up (and this is something I personally observed when running the testcontainers-go test suite on WSL), since Ryuk is not aware of them.

We solved this issue in testcontainers-java by registering the project label added by Docker Compose with Ryuk:
