Docker-compose守护进程退出

Question

所以我将Play框架与Docker一起使用(特别是使用此图像),并尝试启动并运行服务器.

干

$ sudo docker-compose run web activator run

按预期工作:网络服务器启动并保持接受传入请求.

但后来我试试

$ sudo docker-compose up -d

和

$ sudo docker-compose logs
...

它退出了!这是为什么？为什么它不像我一样继续运行docker-compose run？

编辑 - 我的docker-compose.yml文件

database:
  image: postgres:9.1
  volumes:
    - /ShallWeDebate/postgres-entrypoint:/docker-entrypoint-initdb.d:ro
  env_file:
    - ./vars.env
web:
  image: ingensi/play-framework
  volumes:
    - /ShallWeDebate:/app:rw
  env_file:
    - ./vars.env
  links:
    - database
  ports:
    - "80:9000"

如果您想要一个在开发模式而非生产模式下与Play应用程序一起使用的解决方案,您可以将该stdin_open: true设置添加到您的docker-compose.yml文件中:

web:  
  image: brikis98/ping-play
  ports:
    - "9000:9000"
  stdin_open: true

在上面的示例中,brikis98/ping-play图像是activator run默认执行的Play应用程序.如果我docker-compose up在上面的YAML文件上运行,Play应用程序会启动并继续运行而不是立即退出.
