Instance Attribute Details

#catalog_format ⇒ Integer

Returns catalog format version number. This value is constant for a given version of Puppet; it is incremented when a new release of Puppet changes the API for the various objects that make up the catalog.

Returns:

  • (Integer) —

    catalog format version number. This value is constant for a given version of Puppet; it is incremented when a new release of Puppet changes the API for the various objects that make up the catalog.

#apply(options = {}) {|transaction| ... } ⇒ Puppet::Transaction

Apply our catalog to the local host.

Parameters:

Options Hash (options):

  • :report (Puppet::Transaction::Report) —

    The report object to log this transaction to. This is optional, and the resulting transaction will create a report if not supplied.

  • :tags (Array[String]) —

    Tags used to filter the transaction. If supplied then only resources tagged with any of these tags will be evaluated.

  • :ignoreschedules (Boolean) —

    Ignore schedules when evaluating resources

  • :for_network_device (Boolean) —

    Whether this catalog is for a network device

Yields:

  • (transaction)
