Secvault

Simple YAML secrets management for Rails. Uses standard YAML anchors for sharing configuration.

Installation

gem 'secvault'

Usage

1. Add to initializer:

# config/initializers/secvault.rb
Secvault.start!

2. Create secrets file:

# config/secrets.yml
defaults: &defaults
  app_name: "MyApp"

development:
  <<: *defaults
  secret_key_base: "dev_secret"
  api_key: "dev_key"

production:
  <<: *defaults
  secret_key_base: <%= ENV['SECRET_KEY_BASE'] %>
  api_key: <%= ENV['API_KEY'] %>

3. Use in your app:

Secvault.secrets.api_key
Secvault.secrets.app_name

Options

Secvault.start!(
  files: ['config/secrets.yml'],     # Files to load (later files override earlier ones)
  integrate_with_rails: false,       # Add Rails.application.secrets
  set_secret_key_base: true,         # Auto-set Rails.application.config.secret_key_base from secrets
  hot_reload: true,                  # Auto-reload in development
  logger: true                       # Log loading activity
)

Multiple files:

# Later files override earlier ones
Secvault.start!(files: ['secrets.yml', 'local.yml'])

Rails integration:

Secvault.start!(integrate_with_rails: true)
Rails.application.secrets.api_key  # Now available

Secret key base:

# If your secrets.yml has secret_key_base, it's automatically set
# This replaces the need for Rails.application.config.secret_key_base
Secvault.start!(set_secret_key_base: true)  # Default behavior

Advanced

ERB templating:

production:
  api_key: <%= ENV['API_KEY'] %>
  pool_size: <%= ENV.fetch('DB_POOL', '5').to_i %>

YAML anchors for sharing:

defaults: &defaults
  app_name: "MyApp"
  timeout: 30

development:
  <<: *defaults
  debug: true

production:
  <<: *defaults
  timeout: 10  # Override specific values

Development helpers:

reload_secrets!            # Reload files
Secvault.active?           # Check status
