“A remote server automation and deployment tool written in Ruby.”
“Capistrano is written in Ruby, but it can easily be used to deploy any language.”
Run “cap install” on your project folder
Capfile defines requirements for your deployment tasks→
config/deploy.rb shared configuration for all the stages→
config/deploy/*.rb defines multiple stage deployment→
lib/capistrano/tasks where your custom tasks are defined→
Lots of tasks off-the-shelf that integrate with the Ruby on Rails framework
bundler, assets, migrations, Passenger, etc...
You just need to include the gems in your Gemfile and uncomment the require in the Capfile
Sample Capfile
Sample config/deploy.rb
Sample config/deploy/production.rb
Different roles available:
app, web, db
Also, you can define several servers at once, eg:
Available tasks
Deployment
Run 'cap <stage> deploy' on your console
Deployment flow
Rollback
Run 'cap <stage> deploy:rollback' on your console
Rollback flow
You can attach to any step to run custom commands using 'before' and 'after' from Capistrano DSL, eg:
Not a Rails shop?
You might need manual work creating your recipes,although there is some hope in certain cases:
capistrano-node-deploy Node.js apps→capistrano-virtualenv virtualenv python apps→
capistrano-django Django apps→capistrano-go Go apps →
Caveat emptor! Might be old, untested or unsuitable
Where to go from here?
Infrastructure management tools like Chef or Puppet for server provisioning
Continuous integration hooks for automated deployment to staging servers
