I know I did this once before but can''t find docs on how to do it
again.
I have this in a yaml file:
pvdisks:
ec2_pvdisks_m1.small:
disks: /dev/xvdb1
enabled: yes
Loading it with hiera.
Manifest has:
$testkey = hiera(''pvdisks'')
notice ("TESTKEY=$testkey[ec2_pvdisks_m1.small]")
This is printing
TESTKEY=ec2_pvdisks_m1.smalldisks/dev/xvdb1enabledtrue[''ec2_pvdisks_m1.small'']
which obviously is the data picked into a string.
Doug.

I am assuming that things are indeed fine, but this is confusing > matters.I''ve since learned that I have to use hiera_array and hiera_hash, which aren''t documented anywhere. Now I''ve got: ec2_config: instance: m1.small: pvdisks: - /dev/xvdb1 swapvol_size: 2G logvol_size: 64G m1.medium: pvdisks: - /dev/xvdb1 swapvol_size: 2G logvol_size: 64G m1.large: pvdisks: - /dev/xvdb1 - /dev/xvdc1 swapvol_size: 4G logvol_size: 64G and I''ve tried to access the data every witch way. This gives me a syntax error... $pvdisks = hiera_array(ec2_config[''instance''][$::ec2_instance_type][''pvdisks'']) and this: $pvdisks = hiera_array($ec2_config[''instance''][$::ec2_instance_type][''pvdisks'']) gives me: err: Could not retrieve catalog from remote server: Error 400 on SERVER: ec2_config is not an hash or array when accessing it with instance at /truth/sauce/env/prod/modules/role/manifests/base_server.pp:27 on node gfs01.us1.xxx.com Ugh.

This in insanity.
Now I have:
$ec2_config = hiera(''ec2_config'')
if $::ec2_instance_id {
$pvdisks =
$ec2_config[''instance''][$::ec2_instance_type][''pvdisks'']
$pvdisk_count = inline_template(''<%= @pvdisks.length
%>'')
$swapvol_enabled
$ec2_config[''instance''][$::ec2_instance_type][''volumes''][''swap''][''enabled'']
$logvol_enabled
$ec2_config[''instance''][$::ec2_instance_type][''volumes''][''log''][''enabled'']
notice ("HERE0 ($swapvol_enabled) ($logvol_enabled)")
if ($swapvol_enabled == ''true'') {
$swapvol_size
$ec2_config[''instance''][$::ec2_instance_type][''volumes''][''swap''][''size'']
notice ("HERE1")
}
if ($logvol_enabled == ''true'') {
$logvol_size
$ec2_config[''instance''][$::ec2_instance_type][''volumes''][''log''][''size'']
notice("HERE2")
}
notice ("HERE3 $swapvol_size $swapvol_size")
}
The first HERE0 correctly displays ''(true) (true)'' in the
logs.
However, on the very next line, where the condition is if
$swapvol_enabled == ''true'',it returns false. WTF???
