templatizing a configuration file

[Paolo Supino]

Hi

I want to templatize (we use hiera with yaml backend) a configuration file that has the following content:

-------------------

include-and-override=${configDir}/al-runtime.conf

include-and-override=${configDir}/al-ldap.conf

include-and-override=${configDir}/al-cluster.conf

include-and-override=${configDir}/al-jaas.conf

include-and-override=${configDir}/al-internal.conf

include-and-override=${configDir}/al-external.conf

-------------------

 The number of lines and content of the include-and-override directive changes between systems... 

Can it be done? 

TIA 

Paolo

If I were implementing this I would put a list of files in hiera and have my template dump the list into my file. My untested example is below.

Hiera:

---
psconfs:
- al-runtime.conf
- al-ldap.conf
- al-cluster.conf

Puppet class (puppet 3 or higher):

class psthing ($psconfs = []) {
file { '/path/to/conf':
content => template('psthing/mytemplate.erb'),
}
}

Template:

<% @psconfs.each do |file| %>
include-and-override=${configDir}/<%= file %>
<% end %>


There's a similar example here:

Hi Christopher 

Thanx for the reply :) 

If anyone ever looks for a similar problem... 

Someone (don't remember the user's NIC, sorry) on Puupet's IRC channel suggested using Puppet's template iteration (as explained  here: http://docs.puppetlabs.com/guides/templating.html#iteration).
