How to only have one machine running at once?

@vicontiveros00

though the idea behind V2 is that only one is running and the other is on stand-by

Stand-by machines are only implemented for processes in AppsV2 that do not have a [[services]] section defined: Increasing Apps V2 availability

@vicontiveros00

they’re both running all the time.

This is a known problem (?) for non-HTTP apps (?). In our case, multiple machines (same region) serve TCP connections despite the aggregate connection count being within soft_limit.

This is causing problems in my app (a Discord bot, where it responds twice to the same command because he’s running in 2 machines)

Sounds like you need a queue, or an orchestrator like temporal.io / apache airflow?

@vicontiveros00

how can I have only a single machine running or have one on stand-by?

The crudest way is to provision just a single machine per app.
