Capistrano Build Status Code Climate

Documentation

Check out the online documentation of Capistrano 3 hosted via this repository.

Support

Need help with getting Capistrano up and running? Got a code problem you want to get solved quickly?

Get Capistrano support on CodersClan.

Requirements

  • Ruby >= 1.9.3 (JRuby and C-Ruby/YARV are supported)

Capistrano support these source code version control systems out of the box:

  • Git 1.8 or higher
  • Mercurial
  • SVN

Binaries for these VCS might be required on the local and/or the remote systems.

Installation

Add this line to your application's Gemfile:

gem 'capistrano', '~> 3.4.0'

And then execute:

$ bundle install

Capify: make sure there's no "Capfile" or "capfile" present

$ bundle exec cap install

This creates the following files:

├── Capfile
├── config
│   ├── deploy
│   │   ├── production.rb
│   │   └── staging.rb
│   └── deploy.rb
└── lib
    └── capistrano
            └── tasks

To create different stages:

$ bundle exec cap install STAGES=local,sandbox,qa,production

Usage

# list all available tasks
$ bundle exec cap -T

# deploy to the staging environment
$ bundle exec cap staging deploy

# deploy to the production environment
$ bundle exec cap production deploy

# simulate deploying to the production environment
# does not actually do anything
$ bundle exec cap production deploy --dry-run

# list task dependencies
$ bundle exec cap production deploy --prereqs

# trace through task invocations
$ bundle exec cap production deploy --trace

Testing

Capistrano has two test suites: an RSpec suite and a Cucumber suite. The RSpec suite handles quick feedback unit specs. The Cucumber suite features an integration suite that uses Vagrant to deploy to a real virtual server. In order to run the Cucumber suite you will need to install Vagrant and Vagrant supported virtualization software like VirtualBox.

# To run the RSpec suite
$ rake spec

# To run the Cucumber suite
$ rake features

# To run the Cucumber suite and leave the VM running (faster for subsequent runs)
$ rake features KEEP_RUNNING=1

SSHKit

SSHKit is the driver for SSH connections behind the scenes in Capistrano. Depending on how deep you dig, you might run into interfaces that come directly from SSHKit (the configuration is a good example).
