Puppet Function: ora_cis::lookup_setting

Defined in:
lib/puppet/functions/ora_cis/lookup_setting.rb
Function type:
Ruby 4.x API

Overview

ora_cis::lookup_setting(String $key, Any $default_value) ⇒ Any

See the file “LICENSE” for the full license governing this code.

This function uses its current scope te infer what CIS rule is called on what SID. Based on this information a hiera key is constructed. First we look up the most specfic key. Then we lookup the more global key. As an example the following puppet code:

define ora_cis::rules::r_1_2(

Array   $ignore = lookup_setting('ignore', []),
...

beeing called as:

ora_cis::rules::r_1_2 { 'DB02':}

will result in a first lookup of the most specific key

ora_cis::rules::r_1_2::db02::ignore

when this key is not found, it will lookup the more global key beeing:

ora_cis::rules::r_1_2::ignore

If this is also not found, we return the specfied default value

Parameters:

  • key (String)
  • default_value (Any)

Returns:

  • (Any)
