capistrano doesn't respect port - ruby-on-rails-4

Question

I'm deploying to production as follow:
HOSTS = [
'api1.app.io',
'api2.app.io',
'api3.app.io',
'api4.app.io',
'api5.app.io',
'api6.app.io',
'api7.app.io',
'api8.app.io',
'api9.app.io',
'api10.app.io'
].freeze
HOSTS.each do |host|
server host, roles: %i[app web], user: 'deploy', port: 2323
end
although it fails when capistrano tries to ssh into the servers because it still tries to connect using port 22...
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on host api2.app.io: Net::SSH::ConnectionTimeout
Net::SSH::ConnectionTimeout: Net::SSH::ConnectionTimeout
Errno::ETIMEDOUT: Connection timed out - connect(2) for xx.xx.xx.xx:22
Is there any other way to configure the ports?

Answer 1

The :port option should work. If it does not, that it is a bug. Please open a bug report at https://github.com/capistrano/capistrano/issues .
As a workaround, you can also specify the port via the hostname using the <host>:<port> syntax, like this:
HOSTS.each do |host|
server "#{host}:#{port}", roles: %i[app web], user: 'deploy'
end
