ruby-on-rails – 如何在rails应用程序中将sidekiq放入Docker？

我正在使用rails,sidekiq和docker.

我的docker-compose.yml文件

sidekiq:
  build: .
  command: bundle exec sidekiq -C config/sidekiq.yml
  links:
    - db
    - redis

config / sidekiq.yml文件

:pidfile: ./tmp/pids/sidekiq.pid
:logfile: ./log/sidekiq.log
:queues:
  - default

运行docker-compose后,sidekiq服务无法正常启动.

sidekiq_1 | No such file or directory @ rb_sysopen - /testapp/tmp/pids/sidekiq.pid
sidekiq_1 | /usr/local/bundle/gems/sidekiq-3.5.3/lib/sidekiq/cli.rb:365:in `initialize'
sidekiq_1 | /usr/local/bundle/gems/sidekiq-3.5.3/lib/sidekiq/cli.rb:365:in `open'
sidekiq_1 | /usr/local/bundle/gems/sidekiq-3.5.3/lib/sidekiq/cli.rb:365:in `write_pid'
sidekiq_1 | /usr/local/bundle/gems/sidekiq-3.5.3/lib/sidekiq/cli.rb:42:in `parse'

sidekiq_1 | /usr/local/bundle/bin/sidekiq:16:in `load'
sidekiq_1 | /usr/local/bundle/bin/sidekiq:16:in `<main>'
testapp_sidekiq_1 exited with code 1

解决方法

尝试安装卷.您的docker-compose文件应该如下所示(使用Posgtresql作为数据库)：

web:
  build: .
  volumes:
    - .:/myapp
  links:
    - db
    - redis
  ports:
    - "3000:3000"
  command: bundle exec rails server -b 0.0.0.0
sidekiq:
  build: .
  volumes:
    - .:/myapp
  links:
    - db
    - redis
  command: bundle exec sidekiq
db:
  image: postgres
redis:
  image: redis
