Python Cron App (clock process) Procfile help

Does clock process exist in Railway? Like on Heroku: https://devcenter.heroku.com/articles/scheduled-jobs-custom-clock-processes#defining-custom-clock-processes Does it make sence to create Procfile like this

clock: python main.py

clock: python main.py

python app is using schedule (https://github.com/dbader/schedule) module

N/A

Not right now, but you can emulate that by having a process for triggering whatever job you want on a schedule. The concept is the same

Okay, but I deployed with this Procfile and everything work. I guess "clock:" just does nothing in my case? Will be the same if you write web: python main.py And how actually "python main.py" works if it's Poetry project or does it run it in the poetry shell? And what does it mean in Procfile web:, clock:, etc., I just can see that my app is called "clock" in railway. And in general, does it make sense to write something in the Procfile if I have a poetry application that is using "schedule" module in main.py in root? I'm new to deployments so sorry if these will seem like odd questions. Here: https://docs.railway.app/deploy/builds#procfiles I found info about "web:", but it's not web in my case and I can't find info about other options

web and release are the only real supported procfile directives

SHAKA PAKAOP•2y ago

So what would be correct to specify in my case? .

Brody•2y ago

you would need to do an in code cron scheduler

SHAKA PAKAOP•2y ago

Yep I did it using schedule module But what to specify in Procfile then?

Brody•2y ago

send your current procfile

clock: python main.py

clock: python main.py

In terms of code I use poetry, and I have main.py in the project root that run something like this:

import schedule
import time

def job():
    print("I'm working...")

schedule.every(10).seconds.do(job)
schedule.every(10).minutes.do(job)
schedule.every().hour.do(job)
schedule.every().day.at("10:30").do(job)
schedule.every(5).to(10).minutes.do(job)
schedule.every().monday.do(job)
schedule.every().wednesday.at("13:15").do(job)
schedule.every().day.at("12:42", "Europe/Amsterdam").do(job)
schedule.every().minute.at(":17").do(job)

def job_with_argument(name):
    print(f"I am {name}")

schedule.every(10).seconds.do(job_with_argument, name="Peter")

while True:
    schedule.run_pending()
    time.sleep(1)

import schedule
import time

def job():
    print("I'm working...")

schedule.every(10).seconds.do(job)
schedule.every(10).minutes.do(job)
schedule.every().hour.do(job)
schedule.every().day.at("10:30").do(job)
schedule.every(5).to(10).minutes.do(job)
schedule.every().monday.do(job)
schedule.every().wednesday.at("13:15").do(job)
schedule.every().day.at("12:42", "Europe/Amsterdam").do(job)
schedule.every().minute.at(":17").do(job)

def job_with_argument(name):
    print(f"I am {name}")

schedule.every(10).seconds.do(job_with_argument, name="Peter")

while True:
    schedule.run_pending()
    time.sleep(1)

Brody•2y ago

then just do

worker: python main.py

worker: python main.py

SHAKA PAKAOP•2y ago

Brody•2y ago
