I have an elixir / phoenix application wanted to fetch some external boot configurations.
What would be the best way to do this?
If it’s for “production” environment and you are using distillery releases, you might want to check out config providers. Before the config provider runs, you can setup the environment with hooks.
I usually collect the info required for the app to run (like public/private ip addresses, currently active nodes, vpn setup) in a bunch of pre_start hooks, and store it into env vars, then in the release provider, the app reads values from these env vars and stores then into app’s config.
