To make capistrano start, stop, and restart your app using God, override the
deploy:start, deploy:stop, and deploy:restart tasks:
namespace :deploy do
desc "Use god to restart the app"
task :restart do
god.all.reload #ensures any changes to the god config are applied at deploy
god.app.mongrels.restart
# god.web.nginx.restart
# ...
end
desc "Use god to start the app"
task :start do
god.all.start
end
desc "Use god to stop the app"
task :stop do
god.all.terminate
end
end
A few of the tasks in the god:all namespace require the path to your god
configuration file. This defaults to:
"#{current_path}/config/god/#{role}.god"
This can be changed by setting the god_config_path capistrano variable:
require 'san_juan'
set :god_config_path, "/path/to/config"
role :app, 'foo.example.com'
role :web, 'bar.example.com'
san_juan.role :app, %w(mongrels memcached)
san_juan.role :web, %w(nginx)
