Are you using Hiera? We run multiple datacentres that have different
management networks, syslog servers and such, I provide the server with
knowledge of the datacentre with a custom fact (which just reads a file in
my case) and then in the hiera config I have:
:hierarchy:
- nodes/%{hostname}
- common/%{datacentre}
Then anything specific to the datacentre goes in that file. You could
easily do something similar for the network.
Alternatively you might be able to define it all in a case statement
matching the IP address of the server, although depending on how
complicated your network architecture the regexs could become complicated:
case $::ipaddress_eth0 {
/^192.168.1/: { $nameserver = '192.168.1.254' }
/^192.168.2/: { $nameserver = '192.168.2.254' }
}
