How can I let rack execute code on exit (sigterm)? Startet with rackup

I start with rackup --host 0.0.0.0 -p 80, my config.ru file contains the following:

require_relative 'app/config/initializer'

run Manager.freeze.app

# What I need, but does not work.
at_exit do
  Manager.stop_all_services
end

at_exit does not seem to get hit when I stop my docker-console setup. I don't even know if it works for a normal script. Does anyone have an idea how to execute some code when I stop the webserver I started with rackup?

Edit: Removed all non-related docker info, since it was distracting from the original question.

Solution

  • As it turned out at_exit simply works. I think something else in my setup is broken.

    Thanks for your time!
