It may be possible to wrap the duplicate Host resource in an exported
defined type instance:
define site::secondary_host ($ip, $ensure = 'present') {
host { $title: ip => $ip, ensure => $ensure }
}
@@site::secondary_host { ${::hostname}:
ip => $secondary_ip
}
You will not be able to collect that resource on the node that exports it
(you would again -- and rightfully -- get a duplicate resource complaint),
but I think otherwise you should be ok. Specifically, I think Puppet will
avoid evaluating the definition body for instances that are exported, until
and unless they are collected. If that indeed works then it may be a bit
better than your solution because it makes the node's hostname the primary
name of the hosts entry, rather than an alias.
