ruby-on-rails - Docker Rails 应用程序上没有这样的文件或目录@rb_sysopen sidekiq.pid

Question

我试图让它在 EC2 AWS 内运行 rails dockerized 项目容器，但我没有成功运行。

RoR 项目依赖于 sidekiq、postgres 和 redis，因此我使用 docker for rails(Web 服务)和 sidekiq(sidekiq 服务)构建了一个“生产镜像”，目前我尝试使其与 docker-compose 一起用于生产

我不得不说，我本地机器上的一切工作正常。开发和“生产”图像按预期工作，在 EC2 AWS 机器中组合“生产”图像(web 和 sidekiq)时出现问题。

我收到此错误:

在我用于 EC2 生产的 docker-compose.yml 中，我有这个:

version: '3'

services:
  postgres:
    image: postgres:10.5
    environment: 
      POSTGRES_DB: my_app_production
    env_file:
      - ~/production.env

  redis:
    image: redis:4.0.11

  web:
    container_name: prod_web
    image: prod_my_app:latest
    command: bundle exec rails server -p 3000 -b '0.0.0.0' -e production
    ports:
      - '80:3000'
    depends_on:
      - postgres
      - redis
    environment: 
      RAILS_ENV: production 
      RACK_ENV: production 
      RAILS_LOG_TO_STDOUT: 'true' 
      RAILS_SERVE_STATIC_FILES: 'true' 
      EXECJS_RUNTIME: Disabled 
      SECRET_KEY_BASE: token 
      DEVISE_SECRET_KEY: token 
    env_file:
      - ~/production.env
    restart: always

  sidekiq:
    container_name: production_sidekiq
    image: prod_my_app_sidekiq:latest
    command: bundle exec sidekiq -C config/sidekiq.yml
    depends_on:
      - postgres
      - redis
    environment: 
      RAILS_ENV: production 
      RACK_ENV: production 
      RAILS_LOG_TO_STDOUT: 'true' 
      RAILS_SERVE_STATIC_FILES: 'true' 
      EXECJS_RUNTIME: Disabled 
      SECRET_KEY_BASE: token 
      DEVISE_SECRET_KEY: token 
    env_file:
      - ~/production.env
    restart: always`

在 config/sidekiq.yml

:verbose: true
:concurrency: 1
:pidfile: ./tmp/pids/sidekiq.pid
staging:
  :concurrency: 10
production:
  :concurrency: 20
:queues:
  - default
  - mailers

我被卡住了，我原以为这是卷的问题，因为我有另一个文件用于“本地生产测试图像”和绑定(bind)卷: - .:/my_app 在 sidekiq 和 Web 服务中，所以在生产中我删除了这些行提 Docker Compose in Production但我收到错误 production_sidekiq | No such file or directory @ rb_sysopen - /my_app/tmp/pids/sidekiq.pid
Web 服务上的 Puma 服务器运行正常。

知道发生了什么吗？

Answer 1

你不需要 pidfile 那么为什么要创建一个呢？删除这一行:

:pidfile: ./tmp/pids/sidekiq.pid
