Hi, we're trying to re-use some variables that are currently used for
templating a configuration file. We found out these same hosts need to be
in our /etc/hosts file as well, so we'd like to use the built-in host type
to do this, but since our list of hosts is stored as an array, I'm having
some issues.
Here's what we have:
$my_servers = ["server1.domain|1.1.1.1","server2.domain|1.1.1.2"]
Our template does this (we need both the FQDN and the short name in the
config file, for software reasons):
<% my_servers.each do |server| %>
SERVER = <%= server.split('|')[0] %>
SERVER = <%= server.split('|')[0].split('.')[0]
%>
So, how can we re-use the array of data we have so that we don't need to
recreate things?
I was looking at doing something like this:
define multihosts($line) {
$hostname = split($line, "[|]")[0]
$ip = split($line, "[|]")[1]
...
host { "$name_$hostname": name => $hostname, ... }
}
multihosts { foo: line => $my_servers[0] }
But puppet does not seem to like indexing variables inside classes, and I
can't find anywhere in the language reference where to do this currently.
Also, despite the fact that the split() function is in the function
reference, I am getting the following error:
err: Could not retrieve catalog: Unknown function split at
/var/lib/puppet/modules/... on node mynode
So, what am I doing wrong, and what is the best way to proceed?
