ruby-on-rails - 在 Docker 容器上设置 Rails 控制台不接受任何输入

问题描述

我试图在我的 dockerized 容器中设置 Rails 控制台。整个应用程序有多个组件，我已经使用docker-compose. 这是我docker-compose.yml文件中的相关服务。

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

我Dockerfile有以下命令ENTRYPOINT /usr/src/app/docker-entrypoint.sh

而在docker-entrypoint.sh

#!/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

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

控制台启动，我看到了，>>但我无法输入。我哪里错了？

标签： ruby-on-railsdockerdocker-compose

解决方案

尝试使用-i模式启动容器。

-i, --interactive 附加容器的标准输入

就像是

docker-compose -f docker-compose.yml up -i && docker attach application

您也可以根据需要-d混合使用。-i
