heroku-config-rollback

Allow roll back of values of the environment variables to a past release.

Installation

Add the heroku gem plugin:

$ heroku plugins:install git://github.com/guilleiguaran/heroku-config-rollback.git
heroku-config-rollback installed

Usage

The heroku config:rollback command can be used to restore the config variables without roll back full release (app code). Consider the next full example of the flow:

% heroku config
