How to get the current role name in capistrano tasks

I have the following piece of code:

task :back_up, :roles => [:server1, :server2] do

I want to know the role name server1 or server2 where the tasks is being executed. I need this to generate dynamic strings based on the server end

Is this possible?

The on roles block takes an optional argument host, and that host knows what roles are assigned to it.

Example:

task :some_task do
  on roles(:all) do |host|
    puts host.roles.to_a
  end
end

The host is an instance of Capistrano::Configuration::Server, and you can check whether it is related to some specific role like this: host.has_role?(:db).
