Elixir applications in Docker containers?
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 topic for us?

I found only that there could be problem when you want connect with Erlang Vm with another Erlang VM on different machine.

Thanks for the link! Yes, networking is another friction point and a common problem I have with Docker in general.

In a few years Docker will be as good as Solaris zones

A common problem I’ve read about is BEAMs hot-code-swap capabilities, which you seem to give up when using docker.

Check this out, that’s the closest setup I’m using in production, but you kinda give up about code-swap, but at least you have a good envelope (deploy way) for you infrastructure.

It seems like edeliver is the way to go; Plataformatec recently published a blog post about it and it looks easy to setup. It seems to me, unless you already have a Capistrano/Jenkins or Docker deployment pipeline setup, then it will be easier just to use edeliver.
Perhaps we can incorporate some of this information back into our deployment wiki thread.

How do you manage files permissions between containers and development environment?
