EC2 docker networking

I just saw this thread, and I thought I could get useful info, as I am running my dockerized phoenix app behind Amazon Elastic Beanstalk load balancer inspired by this useful article ,

But I don’t know how to let OTP nodes talking with each other, as each OTP node on an individual EC2 instance, how would let OTP nodes get aware of each other? what are the options that I have? I know I can use Redis as a connector, but I prefer the OTP way, as Elixir is already built on top of Erlang, and this should be easy to do, but its my first app to deploy..

Any idea? or gist to share?

Also, isn’t host networking mode better in term of performance than bridge mode?
