I am wondering is it possible to schedule a task to run at certain time in periodic fashion aka. cron style... thinking of having a monitoring task to be run routinely ... i could use a cron on one of the server but prefer to run it on trains as then i am not relying on a single server being up

Yes JitteryCoyote63 I think you are correct, this currently the easiest to do. PompousParrot44 notice that you should have a "services" queue with a trains-agent "services mode" running to enqueue those type pf mostly sleeping services 🙂
I was thinking we can quickly create a service that does that, maybe leverage one of these ?

Hi PompousParrot44 , you could have a Controller task running in the services queue that periodically schedules the task you want to run

ok so controller task is a simple place holder which run infinitely and fetch a task template and queue it..

Thats how I would do it, maybe guys from allegro-ai can come up with a better approach 👍

I don't think there is an example for this use case in the repo currently, but the code should be fairly simple (below is a rough draft of what it could look like)
` controller_task = Task.init(...)
controller_task.execute_remotely(queue_name="services", clone=False, exit_process=True)

while True:
periodic_task = Task.clone(template_task_id)
# Change parameters of {periodic_task} if necessary
Task.enqueue(periodic_task, queue="default")
