How to run Quantum independently in my app as a separate process?

Hi all,

I’ve already setup Faktory (GitHub - contribsys/faktory: Language-agnostic persistent background job server · GitHub) to take care of my background jobs on my app. However, I am trying to setup Quantum (GitHub - quantum-elixir/quantum-core: ⌚ Cron-like job scheduler for Elixir · GitHub) to schedule jobs periodically on my Faktory server.

I’ve gone through the installation instructions, however it seems to involve running Quantum as a supervised application under my actual application:

defmodule MyApp.Scheduler do
  use Quantum, otp_app: :my_app
end

in application.ex:

children = [
 ..,
 .. ,
 MyApp,Scheduler
]

Whenever I run my mix phx.server, it seems to start quantum, however, it gets killed as soon as my phx.server is killed.
I would want to run quantum as a separate process independent from Phoenix server.
Am I missing something here? Can someone please guide me?

Thanks a lot.

The whole idea of Erlang’s OTP is to have tree structure of supervisors and workers which all go down after the OS process is finished.

You are looking for a normal separate OS process daemon.

If you wish to work outside of your application why not use regular cron? It would be simpler than running multiple instances of the VM at the same time.
