delayed-job

问题 I'm hosting a rails project on Amazon Elastic Beanstalk and I try to configure a container command to automatically restart my delayed_job worker on the server after each deployment. I tried with this one : container_commands: restartdelayedjob: command: "RAILS_ENV=production script/delayed_job --pid-dir=/home/ec2-user/pids start" cwd: /var/app/current But, it seems that the pushed version is deployed after the restarting of the worker so the jobs failed to be processed by the worker.

If the worker takes to long to finish, then Heroku will send SIGKILL . In the case of delayed_job , this leaves a locked job in the database that won't get picked up by another worker. I'd like to ensure that jobs eventually finish

问题 I implemented a delayed job in my Rails application, following the instructions.
