join_cluster not working on agents

[kostyrev]

Or maybe I'm using this module wrong.
I've setup one server with

class { 'consul':
  config_hash => {
      'datacenter'  => 'car',
      'data_dir'    => '/opt/consul',
      'ui_dir'      => '/opt/consul/ui',
      'client_addr' => '0.0.0.0',
      'log_level'   => 'INFO',
      'node_name'   => "${hostname}",
      'server'      => true,
      'bootstrap_expect' => 1
  }
}

and three agents with

class { 'consul':
join_cluster => 'test-cluster-vm.car.dmz',
  config_hash => {
      'datacenter'  => 'car',
      'data_dir'    => '/opt/consul',
      'client_addr' => '0.0.0.0',
      'log_level'   => 'INFO',
      'node_name'   => "${hostname}",
      'server'      => false,
  }
}
    consul::service { 'puppetmaster':
        port           => 8140,
    }

But exec exec { 'join consul cluster': is not working 'cause

/usr/local/bin/consul info | grep num

shows nothing on those three agents

I guess I stumbled upon #31
It would be nice if you'd updated README
