在不接受任何输入的Docker容器上设置Rails控制台

Question

app:
    image: <image_name>
    # mount the current directory (on the host) to /usr/src/app on the container, any changes in either would be reflected in both the host and the container
    tty: true
    volumes:
    - .:/usr/src/app
    # expose application on localhost:36081
    ports:
    - "36081:36081"
    # application restarts if stops for any reason - required for the container to restart when the application fails to start due to the database containers not being ready
    restart: always
    depends_on:
    - other-db
    # the environment variables are used in docker/config/env_config.rb to connect to different database containers
    container_name: application
    environment:
    - CONSOLE=$CONSOLE

#!/bin/bash
echo "waiting for all db connections to be healthy... Sleeping..."
sleep 1m
mkdir -p /usr/src/app/tmp/pids/
mkdir -p /usr/src/app/tmp/sockets/
if [ "$CONSOLE" = "Y" ];
then
    echo "Starting Padrino console"
    bundle exec padrino console
fi

当我跑的时候

export CONSOLE=Y
docker-compose -f docker-compose.yml up -d && docker attach application

控制台启动，我看到>，但我无法键入它。我哪里出错了？

尝试使用-i模式启动容器。

-i,--交互式附加容器的STDIN
