Opsworks - 厨师：在运行sidekiq的opsworks厨师钩子里耙

Question

我在opsworks中使用了before_restart.rb钩子，当它运行“rake i18n：js：export”时我遇到了问题。我不知道为什么用这个耙子运行sidekiq。它仅在opsworks的设置阶段失败。当我部署它时，错误消失。

Answer 1

Sidekiq客户端（不是sidekiq服务器）正在运行，因为它是在初始化程序中定义的。当rake运行时，它会加载整个rails应用程序环境。因此，要么允许环境变量在config/initializers/sidekiq.rb中禁用sidekiq客户端，要么确保在运行此实例的实例上正确配置了redis-server。

unless ENV['DISABLE_SIDEKIQ']
  # Sidekiq.configure...
end

DISABLE_SIDEKIQ=true bundle exec rake do:stuff
