Tasks: TOP => server:uptime

Code

namespace :server do

  desc 'Show server uptime'

  task :uptime do

    on roles(:app) do |host|

      puts "#{host.hostname} reports: #{capture(:uptime)}"

    end

  end

end

server 'test-api.domain.tld', roles: 'app', ssh_options: {

    user: fetch(:user),

    forward_agent: true,

    auth_methods: fetch(:password)

}

I can't understand why, any ideas? (Exemple task from http://capistranorb.com/)

roles: 'app'

Should be:

roles: [:app]

At first guess...
