I am still new to the ruby language and I figured I'd share my file_exists
function to see if it is the correct approach and to offer it out there for
people who may have the same issue. We build our vhosts based off a template
and have come across the need to add in items for specific customers in
their vhost. The problem is if you file() and the file does not exist puppet
throws an error and does not continue to run that manifest. The solution was
to add in a file_exists function to allow us to bypass that issue.
require 'puppet'
module Puppet::Parser::Functions
newfunction(:file_exists, :type => :rvalue) do |args|
if File.exists?(args[0])
return 1
else
return 0
end
end
end
define customer::vhost($env, $url = "", $aliases = "") {
if file_exists("customers/$name/$env/web/httpd.conf") == 1 {
$extra = file("customers/$name/$env/web/httpd.conf")
}
file { "$name.conf":
path => "/etc/httpd/conf.d/$name.conf",
owner => root,
group => root,
mode => 644,
require => Package["httpd"],
content => template("customers/cust-vhost.erb"),
}
}
