Can you SSH into your ‘cron’ instance and run `ps aux | grep cron` and see if you get a result for ‘cron -f’ ?

when you run `cron -f` command it essentially looks for a directory like `etc/cron.d/` and loads cron jobs defined in this location.

Uploading your Dockerfile would help in understanding if there’s any issue.
