Dockerized via Walkthrough Phoenix 1.4 app not running

Steps to reproduce

mix phx.new myapp
add Distillery 2.0 to mix.exs
mix release.init
Follow official guide on Deploying with Docker
Configure and build psqldb container with postgress image and user: postgres, password: postgres, database: myapp_prod
docker-compose up

Description of issue

Distillery 2.0
Phoenix 1.4
elixir:1.7.2-alpine
postgres:11.1-alpine
Alpine v 3.8

Am trying to build and run Distillery 2.0 on Docker using the Deploying with Docker guide and a plain Phoenix 1.4 app with PostgreSQL, but after following all of the steps and running docker-compose up, I get:

This page isn’t working
localhost didn’t send any data.

from localhost:4000 and localhost:80 (tried running on both ports)

If I misconfigure the database in the Phoenix app, I do get

web_1     | 09:00:13.938 [error] Postgrex.Protocol (#PID<0.1512.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (localhost:5432): connection refused - :econnrefused

so my docker container is doing something, but when configured properly (I think) I just get:

Release successfully built!
To start the release you have built, you can use one of the following tasks:

    # start a shell, like 'iex -S mix'
    > _build/prod/rel/myapp/bin/myapp console

    # start in the foreground, like 'mix run --no-halt'
    > _build/prod/rel/myapp/bin/myapp foreground

    # start in the background, must be stopped with the 'stop' command
    > _build/prod/rel/myapp/bin/myapp start

If you started a release elsewhere, and wish to connect to it:

    # connects a local shell to the running node
    > _build/prod/rel/myapp/bin/myapp remote_console

    # connects directly to the running node's console
    > _build/prod/rel/myapp/bin/myapp attach

For a complete listing of commands and their use:
