Capistrano::RVM

RVM support for Capistrano v3:

Notes

If you use this integration with capistrano-rails, please ensure that you have capistrano-bundler >= 1.1.0.

If you want solution with RVM/rubies installer included, give a try to rvm1-capistrano3.

Installation

Add this line to your application's Gemfile:

# Gemfile
gem 'capistrano', '~> 3.0'
gem 'capistrano-rvm'

And then execute:

$ bundle install

Usage

Require in Capfile to use the default task:

# Capfile
require 'capistrano/rvm'

And you should be good to go!

Configuration

Everything should work for a basic RVM setup out of the box.

If you need some special settings, set those in the stage file for your server:

# deploy.rb or stage file (staging.rb, production.rb or else)
set :rvm_type, :user                     # Defaults to: :auto
set :rvm_ruby_version, '2.0.0-p247'      # Defaults to: 'default'
set :rvm_custom_path, '~/.myveryownrvm'  # only needed if not detected

RVM path selection: :rvm_type

Valid options are:

• :auto (default): just tries to find the correct path. ~/.rvm wins over /usr/local/rvm
• :system: defines the RVM path to /usr/local/rvm
• :user: defines the RVM path to ~/.rvm

Ruby and gemset selection: :rvm_ruby_version

By default the Ruby and gemset is used which is returned by rvm current on the target host.

You can omit the ruby patch level from :rvm_ruby_version if you want, and capistrano will choose the most recent patch level for that version of ruby:

set :rvm_ruby_version, '2.0.0'

If you are using an rvm gemset, just specify it after your ruby_version:

set :rvm_ruby_version, '2.0.0-p247@mygemset'

or

set :rvm_ruby_version, '2.0.0@mygemset'

Custom RVM path: :rvm_custom_path

If you have a custom RVM setup with a different path then expected, you have to define a custom RVM path to tell capistrano where it is.

Custom Roles: :rvm_roles

If you want to restrict RVM usage to a subset of roles, you may set :rvm_roles:

set :rvm_roles, [:app, :web]

Restrictions

Capistrano can't use RVM to install rubies or create gemsets, so on the servers you are deploying to, you will have to manually use RVM to install the proper ruby and create the gemset.

How it works

This gem adds a new task rvm:hook before deploy task. It sets the rvm ... do ... for capistrano when it wants to run rake, gem, bundle, or ruby.

Check your configuration

If you want to check your configuration you can use the rvm:check task to get information about the RVM version and ruby which would be used for deployment.

$ cap production rvm:check
