Docker container killed after Ctrl +C - docker

Question

I have a nginx and php-fpm containers.
When I'am in my php container in a projet and I exec any command (like vendor/bin/behat or composer update) who takes time and I click on CTRL+C. I'm ejected from the container. I don't know why.. When I click on CTRL+C without executing commands i don't have the problem.
Any idea ?
This is my docker-compose.yml file :

Thank you for your help.

Have you tried running the container in detached mode (-d option)?
> docker run -d [CONTAINER-NAME]
This will cause the container to run in the background. You can still SSH into the running container by:
> docker exec -it [CONTAINER-NAME] bash
Exiting the container once in will not terminate it.
