Configuration server for elixir

I have a use-case where I have a couple of elixir projects that are services communicating over AMQP. Now I want to create a dashboard where I can configure each project separately, the configuration should be dynamic, meaning that the service should be notified when a configuration change occurs, so that it can make modifications to processes running on it.

Is there a mechanism for doing this or something similar available in elixir/erlang ecosystem?
