Question

我正在使用docker-compose up运行Rails + MySQL + Redis。但是，我不知道为什么我的Rails容器将运行30秒然后被杀死。

这是我的 docker-compose.yml

version: '2'
services:
  db:
    image: mysql:5.7
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_DATABASE=pubsub_1_development
      - MYSQL_USER=appuser
      - MYSQL_PASSWORD=password
    ports:
      - "3307:3306"

  redis:
    image: 'redis:4.0-alpine'
    ports:
      - '6379:6379'

  app:
    image: pubsub_1:0.0.1
    command: bundle exec rails s -p 3000 -b '0.0.0.0'
    volumes:
      - ".:/pubsub_1"
    ports:
      - "3001:3000"
    depends_on:
      - db
      - redis
    links:
      - db
      - redis
    environment:
      DB_USER: root
      DB_NAME: pubsub_1_development
      DB_PASSWORD: password
      DB_HOST: db

我注意到日志中有一些错误，但是我不确定在哪里解决此问题。

好像您的Rails App试图在localhost上连接Redis的地方（Redis不可用）。似乎这样会导致整个应用程序服务停止。代替localhost，它应在应用程序的配置中为Redis使用主机名redis。
