etcd is configured to only listen on certain interfaces - set the interface IP address.

IF=$(ip addr show eth0 | sed -n '/inet /{s_[^1-9]*__;s_/.*__;p}')

By default etcd is configured to listen on port 2379 for client communication and on port 2380 for server-to-server communication.

Simplest case

Define module

defmodule Helloer do
  def hola(msg) do
    IO.puts "Hola! #{msg}"

	defmodule TProcesses do
	def listener() do
	receive do
	{:hello} -> IO.puts "hello";
	Other -> IO.puts "other"
	after
	12_000 -> IO.puts "timeout"
	end
	listener()
	end
