I want to define this in YAML:

    ListenIP    => '1.2.3.4',
    ServerAlias => ['example.com', 'foo.example.com'],
    config      => 'DocumentRoot /var/www/sites/example
<Directory /var/www/sites/example/>
    AllowOverride None
    Options +Indexes
</Directory>'

robinbowes

irb(main):028:0> puts ({'ListenIP' => '1.2.3.4',
irb(main):029:2* 'ServerAlias' => ['example.com', 'foo.example.com'],
irb(main):030:2* 'config' => 'DocumentRoot /var/www/sites/example
irb(main):031:2' <Directory /var/www/sites/example/>
irb(main):032:2'     AllowOverride None
irb(main):033:2'     Options +Indexes
irb(main):034:2' </Directory>'}).to_yaml
--- 
config: |-
  DocumentRoot /var/www/sites/example

I have a three-level hiera config: common, environment, node

I was under the impression I could define parts of an hash at each level and hiera would merge them.

ie. given this config:

common.yaml:
---
network:
    forward_ipv4: false

module Puppet::Parser::Functions
    newfunction(:hiera_hash, :type => :rvalue) do |*args|
        if args[0].is_a?(Array)
            args = args[0]
        end

        key = args[0]
        default = args[1]
        override = args[2]

robinbowes

class mod_jk::config{

    require
        ::mod_jk::install

    include
        ::apache::configfile

    apache::confdfile{'mod_jk.conf':
        source => 'puppet:///modules/mod_jk/mod_jk.conf'

robinbowes

class mod_jk::config::workers{

    include
        ::concat::setup

    $file = '/etc/httpd/conf/workers.properties'

    concat{$file:
        notify => Class['::apache::service']
    }

Assume a two-level hiera config (common and nodename).

I have this in common.yaml:

sysctl:
    hugepages:
        buffer: 4194304
        pagesize: 2048

I want to override buffer for a specific node foo, so I have this in foo.yaml:

robinbowes

DEVICE=bond0
ONBOOT=yes
BONDING_OPTS="miimon=80 mode=4"
TYPE=Ethernet
BOOTPROTO=none
-------------------------------
DEVICE=bond0.16
ONBOOT=yes
BRIDGE=vbr16
HOTPLUG=no
