Dear John,
Thanks for your response.
Since I have a large environment setup I was trying to automatize all
setups from puppet, being as much simple as I can.
For example, let's think that I have a puppet server and more than 1000
puppet nodes. So I edit nodes.pp and I declare "server1" and I assign it an
"apache2" module, a "bind9" module and an "ssh" module.
Once this is working I try and create a shorewall firewall erb template for
its rules file, so that it can automatically detect which modules are
declared on the host, and write the relevant lines in the rules file to
open the appropriate ports depending on that. In this example, the erb
template for shorewall rules would be something like:
################################################################################
# This file is centrally mantained by puppet, built from a template located
at #
# Path to file #
################################################################################
<% if classes.include?('apache') -%>
HTTP(ACCEPT) net $FW
<% end -%>
<% if classes.include?('bind') -%>
DNS/ACCEPT net $FW
<% end -%>
<% if classes.include?('ssh') -%>
SSH/ACCEPT net:someips $FW
<% end -%>
But this does not work for me. Could you provide me another clean and smart
way of achieving that? (Our goal would be not having to declare the whole
bunch of servers more than once, even in the nodes.pp file or in any other
place).
