Need help with getting Capistrano up and running? Got a code problem you want to get solved quickly?
- 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
Binaries for these VCS might be required on the local and/or the remote systems.
Add this line to your application's Gemfile:
gem 'capistrano', '~> 3.3.0'
And then execute:
$ bundle install
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
# 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
Capistrano has two test suites: an RSpec suite and a Cucumber suite. The RSpec suite handles quick feedback unit specs. The Cucumber features are 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
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).
