I am learning puppet and setting up modules for some servers. Although I know
this works from my testing, my spidey sense is tingling, and I want to know if
what I am doing is "right."
Say I have 10 servers that use ntp, and company policy is that only two of
them can contact outside sources to get their time sync, thus, these two
servers will then be used by the other 8 servers for their time sync.
Therefore the difference between the 2 servers and the other 8 will basically
be the contents of /etc/ntp.conf
I created an ntp module, and in init.pp, I have:
class ntp {
package { <package stuff> }
file { "/etc/ntp.conf":
owner => "root",
group => "root",
mode => 440,
source => "puppet:///ntp/ntp.client.conf",
require => Package["ntp"],
}
service { <service stuff> }
}
Then I made server.pp that contains
class ntp::server inherits ntp {
File["/etc/ntp.conf"] { source => "puppet:///ntp.server.conf" }
}
Then in nodes.pp, it boils down to:
node basenode { include ntp, ssh, yum }
node ntpserver1 inherits basenode { include ntp::server }
node ntpserver1 inherits basenode { include ntp::server }
node default inherits basenode { }
So basically, all the servers include ntp, but then the "ntpservers" also
include ntp::server. So is this the correct approach, that is to include a
module for all the servers, then overwrite a few server configs using
inheritance where necessary?
Thanks.
