I have just gotten to playing with this and am doing something wrong,
probably very basic.
On the puppetmaster (which for my testing is also the client) I have
create_resources.rb in /var/lib/puppet/lib/puppet/parser/functions.
I wrote a new ENC that will just output a very basic YAML to test this, the
output is:
classes:
yumreposerver:
yumreposerver::locations:
centos5:
distro: centos
version: 5.6
In my modules directory I have yumreposerver/manifests/locations.pp:
class yumreposerver::locations ( $instances = {} )
{
create_resources('yumreposerver::location', $instances)
}
yumreposerver/manifests/location.pp:
define yumreposerver::location( $distro, $version ) {
.....
}
puppet agent -t --noop returns:
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Invalid parameter yumreposerver::locations on node <name>
Puppet version 2.6.9 on SL6.
Any insight as to where I have gone wrong?
Thanks,
jl
