⁠Heroku Java Docker Image

This image is for use with Heroku Docker CLI.

⁠Usage

Your project must contain the following files:

• pom.xml or Build.scala (see the Maven documentation for details⁠)
• Procfile (see the Heroku Dev Center for details⁠)

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/java"
}

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, mvn will download all dependencies into the container, build your application, and then run it. Subsequent runs will use cached dependencies (unless your pom.xml file has changed).

You'll be able to access your application at http://<docker-ip>:8080, where <docker-ip> is either the value of running boot2docker ip if you are on Mac or Windows, or your localhost if you are running Docker natively.

⁠Caveats

If you project has submodules, this image may not work for you.
