How to use Scheduled Cron Tasks #4695
Description
Can someone please clarify how the Scheduled Cron Tasks work? I'm trying to run a rails rake task via the cron, but it doesn't run. The examples don't really show if you're supposed to use dokku in the command or how exactly that works. I also couldn't find any examples online.
My app.json
{
"cron": [{
"command": "rake my_task:import",
"schedule": "@daily"
}]
}
