Ctrl+C terminate attached container but not `docker compose` execution

[luislavena]

Description

Hello folks,

It appears that compose-cli (docker compose) do not terminate execution when hitting Ctrl+C on an attached controller. This behavior is not reproducible compared to docker-compose exact same setup.

I originally thought this could be an issue with WSL2 (not using Docker Desktop for Windows) so decided to compare with a real Ubuntu 20.04 machine and the issue is the same.

Hope was able to provide all the details, but please let me know if additional tests are required.

Thank you for creating Docker and this new compose CLI!!! ❤️ ❤️ ❤️

Cheers.

Steps to reproduce the issue:

1. Create simple docker-compose.yml file with sleep infinity container (see below)
2. Run docker compose up and wait for Attaching notification
3. Press Ctrl+C and wait for Stopped notification

Describe the results you received:

Notice that command does not exit (and requires kill)

Describe the results you expected:

Expected the process to terminate in similar way as docker-compose execution.

Additional information you deem important (e.g. issue happens only occasionally):

Same here. Looks like it broke in the very last release (1.0.9 was fine). I'm also seeing these messages in the console after pressing Ctrl-C:

^CGracefully stopping...
WARNING Unexpected API error for <container_name> : context canceled 
WARNING Unexpected API error for <container_name> : context canceled 

Doing strace on the hung docker compose up process shows it's waiting on a futex. The only way to make it exit is using kill -9.

Thank you @ndeloof, I can confirm this is working great with 1.0.12 release!
