Support interactive in yml configuration

[tsaikd]

Sometimes the docker image will run service in background and enter bash, if not setup stdin_open and tty flag, the container can not enter bash interactive mode to idle.

Thanks for the contribution!

I'm not sure it makes sense to set stdin_open on a container that'll be run with docker-compose up. We can't hook up the terminal's stdin because there may be multiple containers running - which one would we attach to?

If you still feel you need this feature, could you open an issue describing the use case, and why Compose doesn't currently serve it?

The PR was created when docker without exec method for entering the running container.
It's not necessary now.
