Sekreto
Use AWS Secrets Manager from Ruby, with rails support
Installation
Add this line to your application's Gemfile:
gem 'sekreto'And then execute:
$ bundle
Or install it yourself as:
$ gem install sekreto
Usage
Configuration
Configuration will happen automatically in a Rails environment to set defaults that make integrating easy. The defaults look like
Sekreto.setup do |setup|
# Default secrets manager is a new client
setup.secrets_manager = Aws::SecretsManager::Client.new
# Prefix of secrets set to Rails app name and RAILS_ENV
setup.prefix = 'railsappname-staging'
# Allowed environments to use secrets is set to production/staging
# Any block can be given that responds to #call and returns a true or false
# that will use secrets calls if allowed and use the fallback if not
setup.is_allowed_env = -> { %w[production staging].include?(::Rails.env) }
# Default fallback is to look up the secret in the ENV if it is not an
# allowed env to use the secret manager
setup.fallback_lookup = ->(secret_id) { ENV[secret_id] }
endYou can use an initializer to customize any of the defaults
config/initializers/sekreto.rb
Sekreto.setup do |setup|
setup.secrets_manager = Aws::SecretsManager::Client.new
setup.prefix = 'some/other/prefix'
setup.is_allowed_env = -> { ENV.fetch('USE_SECRETS', false) }
setup.fallback_lookup = ->(secret_id) { Secrets.where(name: secret_id).pluck(:value).first }
endRetrieving Secrets
Getting plain text secrets:
# Will query for "#{prefix}/my-secret"
secret = Sekreto.get_value('my-secret')
puts secret
# Output: asdf124asdf134asdf1243asdfGetting JSON secrets will return the parsed value
# Will query for "#{prefix}/my-secret-config"
secret = Sekreto.get_json_value('my-secret-config')
puts secret
# Output: { some: 'json', data: 'here' }Getting secrets with a custom prefix. Useful for shared secrets or secrets across apps, namespaces, etc.
# Will query for "shared-secrets/MY-SECRET-CONFIG"
secret = Sekreto.get_json_value('MY-SECRET-CONFIG', 'shared-secrets')
puts secret
# Output: { some: 'json', data: 'here' }If you want to skip prefixes all together you can pas false to either
get value methods. Not recommended
# Will query for "MY-SECRET-CONFIG"
secret = Sekreto.get_json_value('MY-SECRET-CONFIG', false)
puts secret
# Output: { some: 'json', data: 'here' }Development
