Heroku Feature Deployments

A very simple gem to automate deployment of the current git branch to Heroku, configure DNS, notify PivotalTracker, etc. For more information, see this blog post

Installation

Add this line to your application's Gemfile:

gem 'heroku_feature_deployments', group: :development

And then execute:

$ bundle

Or install it yourself as:

$ gem install heroku_feature_deployments

Outside of Rails you must include the rake tasks manually in your Rakefile

load 'tasks/heroku_feature_deployments.rake'

Configuration

HerokuFeatureDeployments.configure do |config|
  # Heroku Configuration
  config.heroku_api_key = ENV['HEROKU_API_KEY']

  # List of all Heroku addons required
  config.addons = [
    'memcachier:dev', 'sendgrid:starter', 'redistogo:nano'
  ]

  # These environment variables will be added to heroku
  config.env_vars = {
    S3_BUCKET_NAME: 'my-bucket',
    RACK_ENV: 'staging'
  }

  # Prefix all heroku app names with this, to avoid name collisions
  config.namespace = 'a-namespace'

  # Ths name of the heroku account you are using you are using
  # (https://github.com/ddollar/heroku-accounts)
  config.heroku_account_name = 'account-name'

  # The region to deploy the app in (eu/us)
  config.region = 'eu'

  # An array of collaborator email addresses
  config.collaborators = [
    'matt@gmail.com', 'another@gmail.com'
  ]

  # DNS configuration
  config.dnsimple_username = ENV['DNSIMPLE_USERNAME']
  config.dnsimple_api_key = ENV['DNSIMPLE_API_KEY']


  # GitHub Configuration
  config.github_token = ENV['GITHUB_TOKEN']
  # The name of the GitHub repository ('heroku_feature_deployments') for example
  config.github_repo = 'github project name'


  # Pivotal Tracker Configuration
  config.pivotal_tracker_api_key = ENV['PIVOTAL_TRACKER_API_KEY']
  config.pivotal_tracker_project_id = ENV['PIVOTAL_TRACKER_PROJECT_ID']


  # Other
  config.logger = Rails.logger # Defaults to STDOUT
end if defined?(HerokuFeatureDeployments)

Usage

First make sure that you are on the branch that you want to deploy

git checkout branch-name

Then deploy it!

rake hfd:deploy PIVOTAL_TICKET_ID=pivotal ticket ID here

Or alternatively, if this feature does not have a ticket in pivotal:

rake hfd:deploy

Later, when you are finished with it, then you can tear everything down with:

rake hfd:undeploy

Again, make sure that you are on the branch that you want to tear down!
