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

我正在尝试使其在EC2 AWS内运行dockerized项目容器，但运行却没有成功。

RoR项目取决于sidekiq，postgres和redis，因此我使用docker for rails(网络服务)和sidekiq(sidekiq服务)构建了一个“生产镜像”，目前我试图使其与docker-compose一起生产

我不得不说，本地计算机上的所有功能都可以正常工作。开发和“生产”镜像按预期工作，在EC2 AWS机器中组成“生产”镜像(Web和sidekiq)时出现问题。

我收到此错误:

在我的docker-compose.yml用于EC2上的生产中，我有以下内容:

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`

并在config / sidekiq.yml中

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

我被困住了，我以为这是个卷的问题，因为我还有另一个文件用于“本地生产测试镜像”并绑定(bind)了卷:sidekiq和Web服务中有-。:/ my_app，所以在生产中我删除了以下行:提及Docker Compose in Production，但出现错误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？

最佳答案

您不需要一个pidfile，为什么要创建一个？删除此行:

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