How to use Gitlab CI to deploy a Showoff application on Heroku

I have successfully deployed a showoff presentation on Heroku. Because Heroku makes it so easy to integrate Github, I have also been able to add a Github repository that auto-deploys on Heroku.

I want to setup the same thing in Gitlab. Can someone please help me in setting it up?

The app.json used by Github is as follows:

{
  "name": "lunar-teach",
  "scripts": {
  },
  "env": {
    "LANG": {
      "required": true
    },
    "RACK_ENV": {
      "required": true
    }
  },
  "formation": {
  },
  "addons": [

  ],
  "buildpacks": [
    {
      "url": "heroku/ruby"
    }
  ]
}

Use the following .gitlab-ci.yml config:

For this config to work, you need to get your heroku API key.

First define the stages you want to use, If you want to add testing to your CI pipeline, add it here:

stages:
  - staging
  - production

For each stage defined above, ensure you have a corresponding heroku app created, and that each heroku app has a ruby buildpack added.

Now, for some housekeeping, and ensuring everything's upto date

before_script:
  - apt-get update -qy

Now, for each of the stages you defined earlier, describe the ruby version you need.

As of January 2017, showoff uses Ruby v2.2.6, update the image after checking the Ruby documentation

Add the $HEROKU_APP-NAME and the $HEROKU_API_KEY for each stage.

staging:
  image: ruby:2.2
  stage: staging
  script:
    - gem install dpl
    - dpl --provider=heroku --app=$HEROKU_APP-NAME --api-key=$HEROKU_PRODUCTION_API_KEY --strategy=git
  only:
    - staging

production:
  image: ruby:2.2
  stage: production
  script:
    - gem install dpl
    - dpl --provider=heroku --app=gitlab-ci-ruby-test-prod --api-key=$HEROKU_PRODUCTION_API_KEY --strategy=git
  only:
    - master

The complete script looks like this:

stages:
  - staging
  - production

before_script:
  - apt-get update -qy

staging:
  image: ruby:2.2
  stage: staging
  script:
    - gem install dpl
    - dpl --provider=heroku --app=gitlab-ci-ruby-test-prod --api-key=$HEROKU_PRODUCTION_API_KEY --strategy=git
  only:
    - staging

production:
  image: ruby:2.2
  stage: production
  script:
    - gem install dpl
    - dpl --provider=heroku --app=gitlab-ci-ruby-test-prod --api-key=$HEROKU_PRODUCTION_API_KEY --strategy=git
  only:
    - master
