How to use Heroku Worker workstations with custom clocks with PHP programs?

Question

I am new to Heroku. I am trying to achieve something simple (at least I hope), but there seems to be no direct way to do this.

I have a couple of PHP files that I try to run as a scheduled task (every 5 minutes). These runs may take more than 30 seconds several times. Therefore, as I understand it, I need to install them as workplaces.

The Heroku example seems like a complicated example from which I could not figure out how an existing PHP file should be marked as working.

In addition, I would like to schedule this work task to run every 5 minutes. The docs are for custom watches, but there is no example for PHP.

Can someone point me to a tutorial on how to use workflows and plan their Heroku for PHP programs? Something a newbie might follow.

Thank!

Answer 1

The work of the watch process in this case is to call some other piece of code, let's call it a scheduler , with a regular periodic interval. As an argument, let's say that our scheduler will wait for a call every minute. This is how Laravella's scheduler is set up and, therefore, the Heroka clock that I use (and wrote).

Answer 3

clock.py :

from apscheduler.schedulers.blocking import BlockingScheduler
import os
import sys
import logging

logging.basicConfig(stream=sys.stdout,level=logging.INFO)

logging.info('clock init')

sched = BlockingScheduler()

@sched.scheduled_job('interval', minutes=1)
def timed_job():
    //logging.info('log message')
    //use this if you want to run console command
    os.system("php bin/console app:check-feedback")
    //or
    //whatever you want to run that every 1 minutes 

sched.start()

Procfile:

clock: python clock.py

Run this heroku command

$heroku buildpacks:add --index 2 heroku/python

OR add an extra python buildpack to your dyno in the Heroku> app> toolbar settings:

Expand the app. Finally, add dyno to your watchmaking process:

$heroku ps:scale clock=1

Check your logs:

$heroku logs --tail
