If you have reviewed the multistage extension and have wondered how it works, or how you could replicate this without adding another dependency, consider the following example.
Note: This way only really works if you have minimal differences in tasks between stages, if you have extensive staging differences, please consider the advice on deploying to multiple stages.
Enter this in to your config/deploy.rb taking note that the role definitions are inside the task block:
set :application, 'example-website'
task :production do
role :web, "www.capify.org"
set :deploy_to, "/u/apps/#{application}-production/"
set :deploy_via, :remote_cache
after('deploy:symlink', 'cache:clear')
end
task :staging do
role :web, "localhost"
set :deploy_to, "/Users/capistrano/Sites/#{application}-staging/"
set :deploy_via, :copy
after('deploy:symlink', 'cruise_control:build')
end
With that in mind, to deploy you can try something like:
$ cap staging deploy
$ cap staging deploy:restart
