How to use Release config to set a plug static path in an Endpoint on application start?

[LostKobrakai]

Plug options are set at compile time, therefore you can’t override them like that using releases.exs. If you need to change those settings at runtime see the following example for Plug.Session:

Session cookie domain option

And another one from @chrismccord himself: you could make a plug that calls the Plug.Session init, at runtime plug MySession, ... defmodule MySession do def init(opts), do: Plug.Sesson.init(opts) def call(conn, opts) do runtime_opts = Keyword.put(opts, :domain, ...) Plug.Session.call(conn, runtime_opts) end end in this case, I kept init at compiletime, but modified the options before calling the session plug, to do as much work as possible at compile time but you get the idea?…
