Dokku Rollbar is a plugin for Dokku that notifies Rollbar of deployments.
This dokku plugin could be easily modified to support other error trackers (Sentry, etc).
Verified to work on dokku 0.5+, will probably work without modification on early dokku versions.
$ dokku plugin:install https://github.com/iloveitaly/dokku-rollbar.git
The plugin pulls the Rollbar access token from your app's
your environment from
RAILS_ENV. The app environment will default to
RAILS_ENV is not found
No commands. If
ROLLBAR_TOKEN is set, Rollbar will be notified of each deploy.
