I have been thinking about setting up continuous delivery and I wonder: Does running Elixir/OTP within a Docker container put you at a major disadvantage? Will the application be able to use all the CPU cores and in general benefit from OTP’s design? Maybe @jeffweiss can shed some light on the …

@freiden Apparently I never backported the shell script modifications which trap signals and handle calling :init.stop(), it’s only in Distillery. I could probably backport that easily enough, but it may be worth just switching to Distillery if you have the option :wink:
