Hi,
yes, you will need exported resources, and it won't be an easy design at
all.
I imagine it would work roughly like this (assuming Agent 1 runs
central_server and Agents 2 and 3 run slave_server instances).
Sketch of the manifest for the central server:
class central_server {
concat { '/etc/server_config': ... }
Central_server_snippet<<| tag == 'this-cluster' |>>
}
define central_server_snippet($slave_name) {
concat::fragment { "central-server-$name":
target => '/etc/server_config',
content => "something-with $slave_name\n";
}
@@slave_server_snippet { "for-$name": content => "something-with
$ipaddress" }
}
The slave servers do:
class slave_server {
@@central_server_snippet { "$fqdn": slave_name => "$hostname" }
Slave_server_snippet<<| title == "for-$fqdn" |>>
}
The idea being that the central server will not export its settings to
the slaves before they have exported their respective names to him.
Untested and incomplete. YMMV.
Cheers,
Felix
