Question

我想在开发过程中使用docker。好舒服但是在以开发人员模式启动后，请关闭应用程序。

我有docker-compose来制作游戏框架和postgres。

version: '3.7'
services:
  postgres:
    container_name: postgres
    image: postgres
    restart: unless-stopped
    environment:
      POSTGRES_DB: db
      POSTGRES_USER: user_role
      POSTGRES_PASSWORD: pass
    volumes:
    - ${HOME}/docker/volumes/postgres:/var/lib/postgresql/data
    ports:
    - "5432:5432"
    networks:
      - my-net
  scala-back:
    container_name: scala-back
    image: hseeberger/scala-sbt
    restart: unless-stopped
    volumes:
    - ivy:/root/.ivy2
    - type: bind
      source: .
      target: /app
    command: /bin/bash -c 'cd /app && sbt run'
    ports:
      - "80:9000"
    networks:
      - my-net
networks:
  my-net:
    name: my-net
volumes:
  ivy:

docker-compose up之后，我得到了

scala-back    | --- (Running the application, auto-reloading is enabled) ---
scala-back    | 
scala-back    | [info] p.c.s.AkkaHttpServer - Listening for HTTP on /0.0.0.0:9000

我在命令中尝试了screen -d -m sbt run，但这没有帮助。

您应该以{{1}}开始容器。使用选项docker-compose up -d，您的容器将以分离模式启动，并且您的应用程序不应停止。

在Docker中以开发人员模式运行Play应用程序
