Securenv

Securely store and set ENV variables via AWS SSM.

Installation

Add this line to your application's Gemfile:

gem 'securenv'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install securenv

Usage

There are two parts to using securenv:

  1. Setting secure environment variables in SSM via the command line or programatically.
  2. Populating a runtime ENV with values previously stored in SSM.

Set a secure environment variable

You can set values via the command line with securenv set. (Similar to heroku config:set.)

securenv set FOO=bar --app myapp --stage production

Or you can use the short form:

securenv set FOO=bar -a myapp -s production

If you want to set them programtically you can do something like this:

securenv = Securenv::Client.new(app: 'myapp', stage: 'dev')
securenv.set(variable: 'FOO', value: 'bar')

Using secure environment variables in your app

Before or during the boot stage of your app you can require securenv and give it a list of ENV variables to populate.

require 'securenv'

securenv = Securenv::Client.new(
  app: 'myapp', # For rails you could use Rails.application.class.module_parent.name
  stage: ENV['STAGE'] # For rails you might use ENV['RAILS_ENV']
)

securenv.populate_env

Then you'll be able to use ENV['FOO'] (and others) to access the value that you set previously.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
