Ruby on rails 在Docker中启动sidekiq时出错：“0”；请将sidekiq指向Rails 4/5应用程序“；

Rails 5.2，Docker Compose，Sidekiq，Redis

这是docker compose文件：

version: '3.6'

services:
  redis:
    image: 'redis:4.0-alpine'
    command: redis-server
    ports:
      - '6379:6379'
    volumes:
      - 'redis:/data'

  sidekiq:
    depends_on:
      - 'redis'
    build: .
    command: bundle exec sidekiq -C config/sidekiq.yml
    volumes:
      - './:/app'
    env_file:
      - '.env'

  api:
    build: .
    volumes:
      - './:/app'
    working_dir: /app
    command: puma
    ports:
      - 3000:3000
    depends_on:
      - db
      - redis
    environment:
      DATABASE_URL: postgres://postgres@db
  db:
    image: postgres:10.3-alpine

volumes:
  redis:
  postgres:

sidekiq似乎找不到我的Rails应用程序

如果我将sidekiq改为这样开始：

    command: bundle exec sidekiq -C config/sidekiq.yml -r /app

然后我得到这个错误：

2019-05-27T20:27:59.770Z 1 TID-gr1e0d7n5 INFO: Booting Sidekiq 5.1.1 with redis options {:url=>"redis://redis:6379/0", :id=>"Sidekiq-server-PID-1"}
sidekiq_1  | could not connect to server: No such file or directory
sidekiq_1  |    Is the server running locally and accepting
sidekiq_1  |    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

Spring无法找到您的config/application.rb文件。你的 在/api中检测到项目根，因此spring查找 /api/config/application.rb，但它不存在。您可以配置 通过将Spring.application\u root设置为 config/spring.rb

如果我改为将

working_dir

设置添加到sidekiq：

sidekiq:
    depends_on:
      - 'redis'
    build: .
    command: bundle exec sidekiq -C config/sidekiq.yml
    volumes:
      - './:/app'
    env_file:
      - '.env'
    working_dir: 
      - '/app'

然后我得到这个错误：

2019-05-27T20:27:59.770Z 1 TID-gr1e0d7n5 INFO: Booting Sidekiq 5.1.1 with redis options {:url=>"redis://redis:6379/0", :id=>"Sidekiq-server-PID-1"}

sidekiq_1  |    Is the server running locally and accepting
sidekiq_1  |    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

那么，如何使sidekiq在其容器中正确启动呢

我已经看到了这些答案，它们是相似的，但不是这个特定的错误：

sidekiq似乎找不到Rails应用程序，这是通过添加“工作目录”设置修复的，然后它找不到postgres，所以我不得不添加环境设置以指向postgres

最终的撰写文件是：

    image: postgres:10.3-alpine
    ports:
