I think runtime.exs throws an error that Config is not defined because you have use Config at the top of the file. Try using use Mix.Config in runtime.exs since that matches what you have in prod.exs.

Take a look at hello_elixir to see an example of how a Phoenix app can be setup for Fly.

I gave my shot at updating your runtime.exs:

use Mix.Config

# config/runtime.exs is executed for all environments, including
# during releases. It is executed after compilation and before the
# system starts, so it is typically used to load production configuration
# and secrets from environment variables or elsewhere. Do not define
# any compile-time configuration in here, as it won't be applied.
# The block below contains prod specific runtime configuration.

      raise """

    socket_options: [:inet6],
    url: database_url,
    pool_size: String.to_integer(System.get_env("POOL_SIZE") || "10")

  # The secret key base is used to sign/encrypt cookies and other secrets.
  # A default value is used in config/dev.exs and config/test.exs but you
  # want to use a different value for prod and you most likely don't want

  #
  # For this example you need include a HTTP client required by Swoosh API client.
  # Swoosh supports Hackney and Finch out of the box:
  #
  #     config :swoosh, :api_client, Swoosh.ApiClient.Hackney
  #
  # See https://hexdocs.pm/swoosh/Swoosh.html#module-installation for details.

I noticed your error message talks about not “finding” Mix.Config and also the posted source you have shows you using use Mix.Config, but you’re using elixir 1.12.3 and use Mix.config was deprecated for import Config in Elixir 1.9 Elixir v1.9 released - The Elixir programming language

if I use Config then it says config/3 is not defined for the same code?
