Full Description

This Docker image is deprecated. Please use the Heroku-16 image.
Learn more about local development with Docker Compose and deploying your image to Heroku.

Heroku Scala Docker Image

This image is for use with Heroku Docker CLI.


Your project must contain the following files:

Then create an app.json file in the root directory of your application with
at least these contents:

  "name": "Your App's Name",
  "description": "An example app.json for heroku-docker",
  "image": "heroku/scala"

Install the heroku-docker toolbelt plugin:

$ heroku plugins:install heroku-docker

Initialize your app:

$ heroku docker:init
Wrote Dockerfile
Wrote docker-compose.yml

And run it with Docker Compose:

$ docker-compose up web

The first time you run this command, sbt will download all dependencies into
the container, build your application, and then run it. Subsequent runs will
use cached dependencies (unless your *.sbt files have changed).

You'll be able to access your application at http://<docker-ip>:8080, where
<docker-ip> is either the value of running docker-machine ip default if you are on Mac.
