GTA - the Git Transit Authority

GTA is a git-based deploy tool for moving code from stage to stage.

Heroku has made git deploys an awesome standard. Mislav's git-deploy gem has made this ease of deploy a possibility for servers that are not Heroku too. Despite the easiness of a git deploy system managing a series of stages, ie. origin => ci => staging => production, takes some care and consideration. Additionally, hot-fixing changes in the middle of the chain causes a reordering of commits and different push procedures that can car reek havok.

GTA reads git configuration from yml file that should be checked into source control, assuring the whole team is sharing configurations. There are easy methods for setting up git remotes, and moving code from stage to stage.

Add this line to your application's Gemfile:

gem 'gta'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gta

Make sure you create a gta.yml file in your config directory that looks something like this:

name: app-name

stages:
  origin:
    repository: git@github.com:username/repo.git

  staging:
    source: origin
    repository: git@heroku.com:app-name-staging.git

  qa:
    source: staging
    repository: git@heroku.com:app-name-qa.git

  production:
    source: qa
    repository: git@heroku.com:app-name-production.git

Note: make sure to add require 'gta/tasks' to your Rakefile

The main use case is via rake task. Include the rake tasks via the project Rakefile.
