> Is it possible to have my (Docker) app be run on a machine that wakes on a _schedule_, rather than a request? I’d like for Fly to run my app, say, once every 3 hours, then let it exit.

For cron-like flexibility, the setup is a bit more involved: [Crontab with Supercronic · Fly Docs](https://fly.io/docs/app-guides/supercronic/)

With Scheduled Machines, one can only specify `monthly`, `daily`, or `hourly` intervals: [New feature: Scheduled machines](https://community.fly.io/t/new-feature-scheduled-machines/7398)

One can also wake-up their Machine periodically by sending http reqs from an external service like [Durable Object Alarms](https://blog.cloudflare.com/building-scheduling-system-with-workers-and-durable-objects/).
