Docker-compose standard messaging

I have a project which runs 5 containers within 3 machines so I use 3 docker-compose.yml files - one for each machine.
However, each docker-compose window, shows only ROS2 messages, and std::cerr messages.
From some reason all std::cout (standard output) messages are suppressed.

Is this a normal behavior and how can I change it, in order to see the entire messages?
thank you
