Capistrano::Twelvefactor

Simple capistrano tasks to change environment variables like you would on Heroku.

Add this line to your application's Gemfile:

gem 'capistrano-twelvefactor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-twelvefactor

require 'capistrano/twelvefactor'

Set the file you want to be written to, in order to change environment variables. Usually this would be .env, .bashrc, /etc/environment or something similar, depending on your OS and app setup. The default is .env.

set :environment_file, '.custom_file'

$ cap production config:set[FOO=bar]

Note: If you run zsh, you have to use quotes since square brackets are used for some shell features:

$ cap production "config:set[FOO=bar]"

$ cap production config:unset[FOO]

$ cap production config:list

Same zsh workaround applies here.

Sometimes a change in the environment file requires a restart of your application. Add this to your deploy.rb to do so:

after 'config:set', 'deploy:restart'
after 'config:unset', 'deploy:restart'

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
