Capistrano::Rails

Rails specific tasks for Capistrano v3:

• cap deploy:migrate
• cap deploy:compile_assets

Some rails specific options.

set :rails_env, 'staging'                  # If the environment differs from the stage name
set :migration_role, 'migrator'            # Defaults to 'db'
set :conditionally_migrate, true           # Defaults to false. If true, it's skip migration if files in db/migrate not modified
set :assets_roles, [:web, :app]            # Defaults to [:web]
set :assets_prefix, 'prepackaged-assets'   # Defaults to 'assets' this should match config.assets.prefix in your rails config/application.rb
set :multiple_migration_servers, true      # Defaults to false. If true, it would run migrations on all servers under the migration_role

If you need to touch public/images, public/javascripts and public/stylesheets on each deploy:

set :normalize_asset_timestamps, %{public/images public/javascripts public/stylesheets}

Installation

Add this line to your application's Gemfile:

gem 'capistrano',  '~> 3.1'
gem 'capistrano-rails', '~> 1.1'

Usage

Require everything (bundler, rails/assets and rails/migrations)

# Capfile
require 'capistrano/rails'

Or require just what you need manually:

# Capfile
require 'capistrano/bundler' # Rails needs Bundler, right?
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

Please note that any require should be placed in Capfile, not config/deploy.rb.

Symlinks

You'll probably want to symlink Rails shared files and directories like log, tmp and public/uploads. Make sure you enable it by setting linked_dirs and linked_files options:

# deploy.rb
set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/uploads')
set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')
