I threw this into a hex package
https://hex.pm/packages/external_config

There is an example how we are using it on git repo.

At Manheim we built a small app called env_helper (https://hex.pm/packages/env_helper) to handle environment variables and application variables. The motive was mostly to have default values defined for environment variables that might not be set in development.

Wish we could hot-config apps, as with the Lua config in Nginx Plus. 🙂

Great! It solved my problem connecting a Phoenix application with Postgres via Ecto configuration.

Thank you!

Igor, here is a high level view of what we are doing. Please reach out to me if you want to discuss this further.
We use two approaches:

The first, we use a gen_server that loads a configuration file upon application start–first child in our Supervisor. To get information from config file just send gen_server call message. We also create a ‘reload’ function that will re-read configuration file and update state.

The second option is a copy of Mix.Config–slightly modified. It is a module that can be included in our release. This copy behaves the same way as Mix.Config. Once again we use a gen_server here to load configuration from a file or directory and save state. The good thing about second approach is we can use Config syntax in our configs. This gives us much more flexibility.

In reply to Igor Florian. Let me try to put something together. I am always happy discussing code and systems =]
