Scheduled Tasks or Cronjobs with App Platform Worker

I’m looking to use App Platform for hosting some custom code. This is meant to be a scheduled type of task, so from what I understand, I’d want to set up a Worker component to run in the background. I have seen the docs and repo about the cron using Docker, over in the DigitalOcean-AppPlatform-Cron repo.

But I couldn’t find clarification on details regarding this Worker component. Is it a long running resource? I seem to be getting mixed answers as I search the internet, so I just wanted to be sure. I was thinking that if it was, then I could use something like node-cron within a script, and then have the Worker instance execute this script so that I can run some cron jobs. But I’d love to hear if this wouldn’t work.

Thanks in advance.

Hi there,

Indeed, the Worker components are long running components. The main difference between a Worker component and a Web service component is that the Worker components are not exposed to the internet via HTTP.

The cronjob repo example that you are referring to here:

This is going to be useful if you want to setup an HTTP endpoint that you can hit with that service on a specific schedule. However if you are looking to setup a CLI command instead, you would need to modify that example repo so that you actually deploy your code as well rather than just the cron and curl commands.

What you could do indeed is just fork that repository and extend it so that you could also include your app in there and use the cron service as well.

Let me know if this helps!
