opsworks-dotenv

Configure the environment for you Rails application using OpsWorks, Chef and Dotenv

install

Add the Dotenv gem to your Gemfile

gem 'dotenv-rails'

run bundle

$ bundle

as soon as possible, load the environment through Dotenv

# application.rb
require File.expand_path('../boot', __FILE__)
require 'dotenv'
Dotenv.load

configure

In the OpsWorks stack dashboard click on stack Settings and supply your ENV configuration. For example:

{
  "deploy":{
    "app_name":{
      "symlink_before_migrate":{
        ".env" : ".env"
      },
      "app_env": {
        "YOUR_ENV_KEY": "KEY_VALUE",
        "ANOTHER_ENV_KEY": "SECOND_VALUE"
      }
    }
  }
}

The symlink_before_migrate key just tells OpsWorks to create a link to .env file in shared application folder into current, so it can be picked up by Rails.

You can now deploy your app and enjoy the ENV
