如何使 OS X 上的 docker-compose 与 Play 应用程序一起使用？

Question

我正在尝试通过docker-compose 1.1.0/boot2docker 1.5.0 在 OS X 上运行 Dockerized Play app。但是，它并没有真正发挥作用（请原谅双关语）......

问题是应用程序必须使用伪 TTY（由 Docker 提供）运行，这会使 boot2docker 在尝试附加时挂起。

我通过docker-compose up 运行应用程序，它挂起，如下所示：

> docker-compose up
Recreating exampleapp_web_1...
Attaching to exampleapp_web_1

但是，如果我直接运行应用程序，而不使用 docker-compose，它可以工作：

> docker rm exampleapp_web_1 ; docker run -p 9000:9000 -ti --name exampleapp_web_1 -v `pwd`:/code -v `pwd`/.docker_home:/root exampleapp_web
[info] Loading project definition from /code/project
[info] Set current project to example-app (in build file:/code/)

--- (Running the application, auto-reloading is enabled) ---

[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

(Server started, use Ctrl+D to stop and go back to the console...)

如何让 docker-compose 在我的场景中工作？

docker-compose.yml

web:
  build: .
  command: run
  ports:
    - "9000:9000"
  volumes:
    - .:/code
    - .docker_home:/root
  stdin_open: true
  tty: true

Dockerfile

FROM aknudsen/play-with-node
MAINTAINER Arve Knudsen <arve.knudsen@gmail.com>

COPY ./ /code
WORKDIR /code

EXPOSE 9000

ENTRYPOINT ["sbt"]
CMD ["run"]
