There is supposedly a way to set properties for individual servers. There is only a small sample of this here.

The server options I'm trying to specify don't seem to work so I'm looking for thorough documentation on what those server options are. That's why I'm looking for documentation. Example:

group "servers", "server_big" => { user => 'my_user', private_key => '
+/home/user/key.pem' };

task 'uptime', 'server_big', sub {
  say run 'uptime';
};

The private_key setting is getting ignored and I can't log in.
