Question: auto-sleep / wake-up mechanism

[boustanihani]

Question: Can this module be used in the following scenario =>

I use supervisord to start and stop my server.

Ideally, I would like my server to start when the first request comes in and then stay running as long as more requests are coming in. I would also like to define an idle time after which my server would stop automatically (to save resources) when no more requests are coming in (for example after one minute).

Is it possible to achieve this auto-sleep/wake-up mechanism with this module?

The idea is to host multiple servers on the same PC and let Caddy decide which ones should be running and which ones should go to sleep according to incoming requests.

I'm evaluating the same workflow right now.

I thinkt he best thing we can do is utilizing WakeOnLan, in combination with own services.

• Run a service on the server that should go to sleep, that puts it to sleep if it's CPU/GPU, etc. haven't been utilized for a certain amount of time.
• Use exec if server1.example.com is hit, to trigger a wakeonlan on that servers MAC address

I have all servers on the same machine, so there is only one MAC address :)

Do you want to handle only that one machine regarding sleep, or each of the servers (I suppose VMs) individually?

[boustanihani]

Only one machine with caddy including all other services. The idea is to save resources..
