Envforcer

Enforce environment variable requirements.

Storing configuration in the environment is one of the tenets of a twelve-factor app. However, problems arise when required environment variables aren't set.

Add your required ENV keys to .envforcer.yml:

- REQUIRED_KEY1
- REQUIRED_KEY2
- REQUIRED_KEY3

When the app starts, envforcer will check that all the required variables are set, and raise an error if they are not. This will prevent the app from starting.

Note: Currently only tested with Heroku. Will cause push to be rejected.

Add this line to your application's Gemfile:

gem 'envforcer', require: 'envforcer-rails'

And then execute:

$ bundle

This will add a Railtie to enforce environment variables after_initialize.

At the time you wish to enforce the environment variables, add the line:

Envforcer.enforce
