Heroku Laravel Scheduler

RunScheduler.php

<?php

/**


This Scheduler will run once every minute unlike the Heroku scheduler which only runs every 10 mintues.

To use this scheduler with Laravel 5.4+ add this file to /app/Console/Commands/RunScheduler.php
Register this file in app/Console/Kernel.php

protected $commands = [
...
Commands\RunScheduler::class
...
]

Add this line to your Procfile:

scheduler: php -d memory_limit=512M artisan schedule:cron

Push to Heroku and you will see you have a new dyno option called Scheduler, start ONE only.

I highly recommend using Artisan::queue to run your cron jobs so that your scheduler does not over run.

Sorry i completely missed this message. Hopefully you have figured it out by now :-).

See my message here for full details https://stackoverflow.com/questions/35151297/how-to-setup-laravel-5s-task-scheduling-in-heroku/42682908?noredirect=1#comment80872368_42682908

Thank's for this solution! It works like a charm!

For future users, I really recommend using {--queue } in your Procfile.
And for Heroku users, don't forget about active your resource in the Heroku Dashboard ^^

Thank's again @robbydooo !

is this work on Heroku free dynos?

anyone know how to adding worker:run to the scheduler?

I do not believe you can on free dynos, although it has been a long time since I last used this code sorry.

i've been tried it on free dynos. it works.

nice!

I'm completely new to schedulers so I'm somewhat confused on how to implement this and run my scheduled tasks at the Kernel.php of my code. Do I have to move them from the Kernel@schedule to the RunScheduler@runScheduler function or do I just need to call something to run my tasks at the Kernel.php? Also, what does the Artisan::$fn('schedule:run'); does?
