mix phoenix.new --no-ecto hello_phoenix

If I remember correctly, letting ecto in makes it look for postgres on the pi. Could probably easily set it up for sqlite?

cd hello_phoenix

cp ../nerves_examples/hello_network/Bakefile .

Add to server: true to config section in config/prod.exs and change http to a specific port (It didn't seem to work setting PORT env variable, but I only tried once. )

# config/prod.exs 
config :hello_phoenix, HelloPhoenix.Endpoint,
  http: [port: 80],
  url: [host: "example.com", port: 80],
  cache_static_manifest: "priv/static/manifest.json",
  server: true

Add hello_network to mix.exs dependencies:

# mix.exs
  defp deps do
    [{:phoenix, "~> 1.1.4"},
     {:phoenix_html, "~> 2.4"},
     {:phoenix_live_reload, "~> 1.0", only: :dev},
     {:gettext, "~> 0.9"},
     {:cowboy, "~> 1.0"},
     {:hello_network, path: "../nerves-examples/hello_network"}
    ]
  end

MIX_ENV=prod bake firmware --target rpi2

Haven't figured out why it doesn't start with MIX_ENV=dev

The dev environment tries to start the code reloader, which craps out on nerves.
