Compose: Pipe to compose run

[polonskiy]

How to pipe data to container sdtin?

test:
    image: ubuntu
    stdin_open: true
    command: tailf /dev/null

echo hello | docker-compose run test cat

Doesn't work.

I know how to do it with docker exec, but I'm interested in "compose-way" solution.

I can confirm this is the current behavior, docker-compose freezes. It works if docker run is called directly, though. I don't see a reason why docker-compose run should differ from docker run in this behavior.

I would love to see this fixed and volunteer to help, but first I'd like some feedback from the community to see if I'm on the right track since this would be my first contribution to docker-compose.

I'm having issues with this as well. Is there a work around, other than just using the regular docker command?

I moved from docker-compose to crowdr

This is working for me on master (with the example provided above).

We fixed some bugs in dockerpty in june which probably fixed this. The fixes are in the 1.4.x releases.

I updated to docker-compose version 1.4.2 and can confirm that the issue no longer happens. Thanks for the great work, everyone!
