Easier configuration and deployment of Rails apps on Heroku
Configure your Heroku environment via a YML file (config/heroku.yml) that defines all your environments, addons, and environment variables.
Heroku Rails also handles asset packaging (via jammit), deployment of assets to s3 (via jammit-s3).
Add this to your Gemfile:
group :development do gem 'heroku-rails' end
To install add the following to config/environment.rb:
Rake tasks are not automatically loaded from gems, so you’ll need to add the following to your Rakefile:
begin require 'heroku/rails/tasks' rescue LoadError STDERR.puts "Run `rake gems:install` to install heroku-rails" end
In config/heroku.yml you will need add the Heroku apps that you would like to attach to this project. You can generate this file and edit it by running:
rails generate heroku:config
Then edit config/heroku.yml with your project's heroku configurations. To persist the changes onto Heroku, just run:
rake all heroku:setup
This will create the heroku apps you have defined, and create the settings for each.
After configuring your Heroku apps you can use rake tasks to control the apps.
rake production heroku:deploy
A rake task with the shorthand name of each app is now available and adds that server to the list that subsequent commands will execute on. Because this list is additive, you can easily select which servers to run a command on.
rake demo staging heroku:restart
A special rake task 'all' is created that causes any further commands to execute on all heroku apps.
Need to add remotes for each app?
rake all heroku:remotes
A full list of tasks provided:
rake all # Select all Heroku apps for later command rake heroku:deploy # Deploys, migrates and restarts latest code. rake heroku:apps # Lists configured apps rake heroku:info # Queries the heroku status info on each app rake heroku:console # Opens a remote console rake heroku:capture # Captures a bundle on Heroku rake heroku:remotes # Add git remotes for all apps in this project rake heroku:migrate # Migrates and restarts remote servers rake heroku:restart # Restarts remote servers rake heroku:setup # runs all heroku setup scripts rake heroku:setup:addons # sets up the heroku addons rake heroku:setup:collaborators # sets up the heroku collaborators rake heroku:setup:config # sets up the heroku config env variables rake heroku:setup:domains # sets up the heroku domains rake heroku:setup:stacks # sets the correct stack for each heroku app rake heroku:db:setup # Migrates and restarts remote servers
You can easily alias frequently used tasks within your application's Rakefile:
task :deploy => ["heroku:deploy"] task :console => ["heroku:console"] task :capture => ["heroku:capture"]
With this in place, you can be a bit more terse:
rake staging console rake all deploy
You can easily hook into the deploy process by defining any of the following rake tasks:
You can generate these automatically within lib/tasks/heroku.rake by running:
rails generate heroku:callbacks
Then edit the rake tasks to provide custom logic for each of these steps
namespace :heroku do # runs before all the deploys complete task :before_deploy do end # runs before each push to a particular heroku deploy environment task :before_each_deploy do end # runs after each push to a particular heroku deploy environment task :after_each_deploy do end # runs after all the deploys complete task :after_deploy do end end
