Puppet - Pass hash as class argument

Question

Trying to do something like this:

# nodes.pp
node 'dev-a-1.sn1.vpc1.example.com' inherits project_j1n_sn1_vpc1_dev {

    class { 'custom::core':
        overrides => {
            'openssh' => {'settings' => {'external_access' => 'true'}}, # Allow direct mounting for dev
            'rsyslog' => {'settings' => {'role' => 'node', 'filters' => {'php' => {'target' => 'remote'}, 'mail' => {'target' => 'remote'}}}}
        }
    }
}

# custom::core
class custom::core($overrides = {}) {

    if (has_key($overrides, 'openssh')) {

        $settings = $overrides['openssh']['settings']

        # Doesn't work
        create_resources('openssh', $settings)

        # Doesn't work
        class { 'openssh': $settings }
    }
}

Is it possible to call a class and pass the hash as arguments?

Answer 1

One of my colleagues came up with a good solution for something similar in the old 2+days of the puppet. Used create_resourcesfor this.

http://www.followski.com/quick-note-how-to-use-create_resources-to-initialize-a-class-in-puppet/

your code might look something like this:

nodes.pp

node 'dev-a-1.sn1.vpc1.example.com' inherits project_j1n_sn1_vpc1_dev {

    class { 'custom::core':
        overrides => {
            'openssh' => {'settings' => {'external_access' => 'true'}}, # Allow direct mounting for dev
            'rsyslog' => {'settings' => {'role' => 'node', 'filters' => {'php' => {'target' => 'remote'}, 'mail' => {'target' => 'remote'}}}}
        }
    }
}

order :: core

class custom::core($overrides = {}) {

    if (has_key($overrides, 'openssh')) {

        $settings = $overrides['openssh']['settings']

        create_resources('class', { 'openssh' => $settings })
    }
}

, create_resources('class', $params), , , (.. openssh), , . , , .

node :

node 'dev-a-1.sn1.vpc1.example.com' inherits project_j1n_sn1_vpc1_dev {

    class { 'custom::core':
        overrides => {
            'openssh' => {'external_access' => 'true'}, # Allow direct mounting for dev
            'rsyslog' => {'role' => 'node', 'filters' => {'php' => {'target' => 'remote'}, 'mail' => {'target' => 'remote'}}}
        }
    }
}

:

class custom::core($overrides = {}) {
  if (has_key($overrides, 'openssh')) {
    create_resources('class', {'openssh' => $overrides['openssh'])
  }

  if (has_key($overrides, 'rsyslog')) {
    create_resources('class', {'rsyslog' => $overrides['rsyslog'])
  }
}
