Ok, going back in SVN history...
The nodes file:
node /dns[0-9]+/ inherits globals {
$dns_role = $hostname ? { # needs to be either "master" or "slave"
/dns01/ => [ "master" ], # the 01 box is always the
master by convention
default => [ "slave" ],
}
include "defaults"
include "host2dns"
}
The hosts2dns class has this in part of a file section:
"${basedir}/scripts/host2dns.sh":
owner => "0",
group => "0",
mode => "0550",
ensure => present,
content =>
template("OBFUSCATED/host2dns/host2dns.sh.erb");
...and the template:
#
# This line generated by Puppet based on config variables.
# Only copy zone files into place if we're a master.
#
<% if has_variable?("dns_role") && dns_role == "master" then %>
cp -f $startdir/zones/* /var/named/internal/
<% end %>
rndc reconfig -noexpired
rndc reload
...everything else in it is straight shell. So with this template -
the line with "cp" in it is *never* included in the generated file on
both the master and slave boxes. It just never works.
So by comparison, the same "host2dns" class has this in the files section:
"/etc/named.conf":
owner => "0",
group => "0",
mode => "0444",
ensure => present,
content =>
template("OBFUSCATED/host2dns/named.conf.erb");
...and these template contents in named.conf.erb:
// this line generated by Puppet based on config variables
<% if has_variable?("dns_role") && dns_role != '' then -%>
include "/etc/apple_zones_<%= dns_role %>.conf";
<% end -%>
...result in this:
// this line generated by Puppet based on config variables
include "/etc/apple_zones_master.conf";
That's the last line in named.conf, just telling the box to include
the correct zones depending on master vs slave status. So it seems
that Puppet is totally happy to detect if dns_role is empty, but not
happy to tell me if it contains the value "master".
What is wrong here?
Thanks for following along, if you're still with me. ;)
