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

Overview

postgresql::postgresql_acls_to_resources_hash(Any *$args) ⇒ Data type

This is an autogenerated function, ported from the original legacy version. It /should work/ as is, but will not have all the benefits of the modern function API. You should see the function docs to learn how to add function signatures for type safety and to document this function using puppet-strings.

puppet.com/docs/puppet/latest/custom_functions_ruby.html

—- original file header —- postgresql_acls_to_resources_hash.rb —- original file header —-

suitable for create_resources. It is not intended to be used outside of the
postgresql internal classes/defined resources.

@return This function accepts an array of strings that are pg_hba.conf rules. It
will return a hash that can be fed into create_resources to create multiple
individual pg_hba_rule resources.

The second parameter is an identifier that will be included in the namevar
to provide uniqueness. It must be a string.

The third parameter is an order offset, so you can start the order at an
arbitrary starting point.

Parameters:

  • *args (Any) —

    The original array of arguments. Port this to individually managed params to get the full benefit of the modern function API.

Returns:

  • (Data type) —
