Laravel Artisan CLI safely stop daemon queue workers

Question

In order to process large numbers of jobs, I run a variable number of queue workers depending on howmuch work there is to complete. I don\'t want to run more workers than ar

Answer 1

Since Laravel 5.5 there is an event called Illuminate\Queue\Events\Looping that gets fired from the daemonShouldRun() call inside the main worker loop of Illuminate\Queue\Worker. So if you setup a listener to do your should process jobs check, and return false then the queue worker(s) will stop until the check returns true. There's a sleep between the next time it checks it which you can customise by passing --sleep to the queue:work command.

I'm currently using this technique during deployments to stop workers which run inside docker containers, as it's not so easy to run the suggested queue:restart on them without hacking around.
