ruby-on-rails - 在 Docker : "Please point sidekiq to a Rails 4/5 application" 中启动 sidekiq 时出错

Question

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。

如果我将 sidekiq 更改为这样开始:

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

然后我得到这个错误:

Spring was unable to find your config/application.rb file. Your project root was detected at /api, so spring looked for /api/config/application.rb but it doesn't exist. You can configure the root of your application by setting Spring.application_root in 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  | 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"?

那么如何让sidekiq在其容器中正确启动呢？

我看过这些答案，它们很相似但不是这个特定的错误:

Question 1

Question 2

Question 3

Question 4

Answer 1

sidekiq 似乎找不到 Rails 应用程序，通过添加 'working-dir' 设置修复，然后它找不到 postgres，所以我不得不添加环境设置以指向 postgres。

最终的合成文件是:

version: '3.6'

services:
  db:
    image: postgres:10.3-alpine
    ports:
      - '5432:5432'

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

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

  api:
    build: .
    volumes:
      - './:/app'
    working_dir: /app
    command: puma

    depends_on:

      - redis
    environment:
