not sure if this is the best way to do this, but, taking from a different
module I have:
hiera yaml:
snmp_filesystems:
root: {
mountpoint: '/',
threshold: '10%'
}
snmp_collector:
test: {
ip:'1.2.3.4',
group: 'readonly',
community: 'somecommunity'
}
class:
class snmp::params(
filesystems = hiera(snmp_filesystems, undef),
collector = hiera(snmp_collector, undef)
{
#…
}
template:
%
collector = scope.lookupvar('snmp::params::collector')
filesystems = scope.lookupvar('snmp::params::filesystems')
-%
% collector.each_pair do |key, hash| -%
group %=hash['group']-% v2c %=key%
%end-%
# Filesystem monitoring enabled
% filesystems.each_pair do |key, hash| -%
# %=key%
disk %=hash['mountpoint']-% %=hash['threshold']%
%end-%
does that help at all?

Hi,
I'm trying to build a module for haproxy which fetches all the configuration
data from Hiera to populate the haproxy config file. I've run into a number
of issues though when I try to use hashes. Ideally, I want to use something
like this:
haproxy_listeners :
cluster1 :
ip : '192.168.0.2'
port : '80'
servers :
server1 :
ip : '192.168.0.3'
port : '8080'
So a hash of clusters with each cluster containing a nested hash of servers.
Is this possible with Hiera/ERB? It's easy enough to iterate over the first
hash, but I can't work out how to extract the contents of the nested hash. Or
I might just be approaching this in entirely the wrong way... Any help would
be much appreciated.
I haven't used the function myself, but this looks like it would be a good
case for a define + create_resources(), which I think is part of stdlib. You
might need to restructure the hashes slightly, but I think that will be the
best approach.
Thanks,
Andy
