A simple Rails gem that uses the Heroku Platform API to restart dynos

Add this line to your application's Gemfile:

gem 'heroku_dyno_restarter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install heroku_dyno_restarter

First create an oauth token:

$ heroku plugins:install heroku-cli-oauth
$ heroku authorizations:create -d "Dyno Restarter Token"
Created OAuth authorization.
  ID:          1f02bba0-e5d2-4773-bf4e-2e320bb006cb
  Description: Dyno Restarter Token
  Scope:       global
  Token:       c3dd6bd6-126b-224e-b2be-c9fe52bc1ec6

And store that oauth token in an environment variable called HEROKU_OAUTH_TOKEN

To restart a specific dyno pass the application name and the dyno name:

HerokuDynoRestarter.restart_dynos('my-test-application', 'web.2')

To restart all dynos of an application, pass the application name without a dyno name:

HerokuDynoRestarter.restart_dynos('my-test-application')

To restart all dynos of a specific type, pass the application name and type [web/worker/foo]

HerokuDynoRestarter.restart_dynos('my-test-application', 'web')

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
