Application_Ruby Cookbook

A Chef cookbook to deploy Ruby applications.

Quick Start

To deploy a Rails application from git:

application '/srv/myapp' do
  git 'https://github.com/example/myapp.git'
  bundle_install do
    deployment true
    without %w{development test}
  end
  rails do
    database 'sqlite3:///db.sqlite3'
    secret_token 'd78fe08df56c9'
    migrate true
  end
  unicorn do
    port 8000
  end
end

Requirements

Chef 12.1 or newer is required.

All actions and properties are the same as the bundle_install resource.

• :reload – Send the configured reload signal to the service.

Properties

• path – Base path for the application. (name attribute)
• port – Port to listen on. (default: 80)

The application_rails resource

application '/srv/myapp' do
  rails do
    database 'sqlite3:///db.sqlite3'
    secret_token 'd78fe08df56c9'
    migrate true
  end
end

Actions

• :deploy – Create config files and run required deployments steps. (default)

Properties

• path – Base path for the application. (name attribute)
• app_module – Top-level application module. Only needed for the :initializer style of secret token configuration. (default: auto-detect)

• secrets_mode – Secrets configuration mode. Set to :yaml to generate a Rails 4.2 secrets.yml. Set to :initializer to update config/initializers/secret_token.rb. (default: auto-detect)

NOTE: At this time secrets_mode :initializer is not implemented.

Database Parameters

The database parameters can be set in three ways: URL, hash, and block.

If you have a single URL for the parameters, you can pass it directly to database:

rails do
  database 'mysql2://myuser@dbhost/myapp'
end

Passing a single URL will also set the $DATABASE_URL environment variable automatically for compatibility with Heroku-based applications.

As with other option collector resources, you can pass individual settings as either a hash or block:

rails do
  database do
    adapter 'mysql2'
    username 'myuser'
    host 'dbhost'
    database 'myapp'
  end
end

rails do
  database({
    adapter: 'mysql2',
    username: 'myuser',
    host: 'dbhost',
    database: 'myapp',
  })
end

application_ruby

The application_ruby resource installs a Ruby runtime for the deployment.

application '/srv/myapp' do
  ruby '2.2'
end

All actions and properties are the same as the ruby_runtime resource.

application_ruby_gem

The application_ruby_gem resource installs Ruby gems for the deployment.

application '/srv/myapp' do
  ruby_gem 'rake'
end

All actions and properties are the same as the ruby_gem resource.

application_ruby_execute

The application_ruby_execute resource runs Ruby commands for the deployment.

application '/srv/myapp' do
  ruby_execute 'rake'

All actions and properties are the same as the ruby_execute resource, except that the cwd, environment, group, and user properties default to the application-level data if not specified.
