A fly app with `min_machines_running=1` is scaled to zero

If min_machines_running=1 the app should not scale to zero. Instead i have the app with name minecord-rust-server continuously scaled to zero

When I first deployed the app I forgot to add the primary_region field in fly.toml, maybe that’s the issue? But even after adding it the app is scaled to zero

Hi,

Do you also have auto_stop_machines set?

It seems it needs that too (as well as the primary region):

To keep one or more Machines running all the time in your primary region, set min_machines_running to 1 or higher. min_machines_running has no effect unless you set auto_stop_machines = true.

min_machines_running does not apply to Machines running in non-primary regions. For example, if min_machines_running = 1 and there’s no traffic to your app, then Fly Proxy will stop Machines until eventually there is only one Machine running in your primary region.

Hi,

Other than declaring the primary region, you must also have machines in said primary region. I see you did create a machine in your primary region today (fly scale count 1 --region MY_PRIMARY_REGION), so I would expect this to work well for you now. Note that other non-primary regions will still scale to zero machines if there’s no request load for them.
