With hiera you can only specify keys, not elements of a hash.

you should change this to:

$custom_mysql_options = hiera(‘mysqlconfig::custom_mysql_options’)

You can now set a new variable reading the hash element:

$datadir = $custom_mysql_options[‘datadir’]

That's not the case with Hiera 2.0+ which supports drilling down into
hashes and arrays... so you should also be able to do

$datadir = hiera('mysqlconfig::custom_mysql_options.datadir')

If you're still on Hiera 1.0 though, what Martin said.

[Puppet Users] Newbie question about fetching specific value of a key from hash

[Sam]

My hiera entries -

mysqlconfig::custom_mysql_options:
  mysqld:
replicate-ignore-db: 'test'
server-id: 12
datadir: '/data/mysql_data'


I want to get the value of datadir in my puppet module. Please let me know 
what is the syntax I need to use to fetch this value. I tried something as 
follows but it doesn't work. 


$datadir = hiera('mysqlconfig::custom_mysql_options[datadir]')

  file { "$datadir":
ensure => directory,
owner  => 'mysql',
group  => 'mysql',
mode   => '0755',
  }


Thanks in advance
Sam
