capistrano-rbenv

Capistrano::rbenv

This gem provides idiomatic rbenv support for Capistrano 3.x (and 3.x only).

Please Note

If you want to use this plugin with Cap 2.x, please use 1.x version of the gem. Source code and docs for older integration is available in another repo

Thanks a lot to @yyuu for merging his gem with official one.

Installation

Add this line to your application's Gemfile:

gem 'capistrano', '~> 3.9'
gem 'capistrano-rbenv', '~> 2.2'

And then execute:

$ bundle install

Usage

# Capfile
require 'capistrano/rbenv'


# config/deploy.rb
set :rbenv_type, :user # or :system, or :fullstaq (for Fullstaq Ruby), depends on your rbenv setup
set :rbenv_ruby, '2.4.2'

# in case you want to set ruby version from the file:
# set :rbenv_ruby, File.read('.ruby-version').strip

set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec"
set :rbenv_map_bins, %w{rake gem bundle ruby rails}
set :rbenv_roles, :all # default value

If your rbenv is located in some custom path, you can use rbenv_custom_path to set it.

Defining the ruby version

To set the Ruby version explicitly, add :rbenv_ruby to your Capistrano configuration:

# config/deploy.rb
set :rbenv_ruby, '2.4.2'

Alternatively, allow the remote host's rbenv to determine the appropriate Ruby version by omitting :rbenv_ruby. This approach is useful if you have a .ruby-version file in your project.
