Puppet Function: postgresql::postgresql_acls_to_resources_hash

Defined in:
lib/puppet/functions/postgresql/postgresql_acls_to_resources_hash.rb
Function type:
Ruby 4.x API

Summary

This internal function translates the ipv(4|6)acls format into a resource suitable for create_resources.

Overview

postgresql::postgresql_acls_to_resources_hash(Array[String] $acls, String[1] $id, Integer[0] $offset) ⇒ Hash

Parameters:

  • acls (Array[String]) —

    An array of strings that are pg_hba.conf rules.

  • id (String[1]) —

    An identifier that will be included in the namevar to provide uniqueness.

  • offset (Integer[0]) —

    An order offset, so you can start the order at an arbitrary starting point.

Returns:

  • (Hash) —

    A hash that can be fed into create_resources to create multiple individual pg_hba_rule resources.
