.clean_opt(opt, val) ⇒ Object

A utility method (public, is used by application.rb and perhaps elsewhere) that munges a command-line option string into the format that Puppet.settings expects. (This mostly has to deal with handling the “no-” prefix on flag/boolean options).

Parameters:

  • opt (String) —

    the command line option that we are munging

  • val (String, TrueClass, FalseClass) —

    the value for the setting (as determined by the OptionParser)

Parameters:

    symbolic reference to an environment name

end

#define_settings(section, defs) ⇒ Object

Define a group of settings.

Parameters:

  • section (Symbol) —

    a symbol to use for grouping multiple settings together into a conceptual unit. This value (and the conceptual separation) is not used very often; the main place where it will have a potential impact is when code calls Settings#use method. See docs on that method for further details, but basically that method just attempts to do any preparation that may be necessary before code attempts to leverage the value of a particular setting. This has the most impact for file/directory settings, where #use will attempt to “ensure” those files / directories.

  • defs (Hash[Hash]) —

    the settings to be defined. This argument is a hash of hashes; each key should be a symbol, which is basically the name of the setting that you are defining. The value should be another hash that specifies the parameters for the particular setting. Legal values include:

    [:default] => not required; this is the value for the setting if no other value is specified (via cli, config file, etc.)
   For string settings this may include "variables", demarcated with $ or ${} which will be interpolated with values of other settings.
   The default value may also be a Proc that will be called only once to evaluate the default when the setting's value is retrieved.
[:desc] => required; a description of the setting, used in documentation / help generation
[:type] => not required, but highly encouraged!  This specifies the data type that the setting represents.  If
   you do not specify it, it will default to "string".  Legal values include:
   :string - A generic string setting
   :boolean - A boolean setting; values are expected to be "true" or "false"
   :file - A (single) file path; puppet may attempt to create this file depending on how the settings are used.  This type
       also supports additional options such as "mode", "owner", "group"
   :directory - A (single) directory path; puppet may attempt to create this file depending on how the settings are used.  This type
       also supports additional options such as "mode", "owner", "group"
   :path - This is intended to be used for settings whose value can contain multiple directory paths, represented
       as strings separated by the system path separator (e.g. system path, module path, etc.).
 [:mode] => an (optional) octal value to be used as the permissions/mode for :file and :directory settings
 [:owner] => optional owner username/uid for :file and :directory settings
 [:group] => optional group name/gid for :file and :directory settings

#flush_cache ⇒ Object

Clear @cache, @used and the Environment.

Whenever an object is returned by Settings, a copy is stored in @cache. As long as Setting attributes that determine the content of returned objects remain unchanged, Settings can keep returning objects from @cache without re-fetching or re-generating them.

Whenever a Settings attribute changes, such as @values or @preferred_run_mode, this method must be called to clear out the caches so that updated objects will be returned.

#override_default(param, value) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Create a new default value for the given setting. The default overrides are higher precedence than the defaults given in defaults.rb, but lower precedence than any other values for the setting. This allows one setting a to change the default of setting b, but still allow a user to provide a value for setting b.

#parse_file(file, allowed_sections = []) ⇒ Puppet::Settings::ConfigFile::Conf

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method just turns a file into a new ConfigFile::Conf instance

Parameters:

#patch_value(param, value, type) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Patches the value for a param in a section. This method is required to support the use case of unifying –dns-alt-names and –dns_alt_names in the certificate face. Ideally this should be cleaned up. See PUP-3684 for more information. For regular use of setting a value, the method []= should be used.

PRIVATE! This only exists because we need a hook to validate the run mode when it’s being set, and

it should never, ever, ever, ever be called from outside of this file.

This method is also called when –run_mode MODE is used on the command line to set the default

is likely to have unused settings in it; any setting that's
valid anywhere in Puppet can be in any config file, even if it's not used.

Every section can specify three special parameters: owner, group, and mode.
These parameters affect the required permissions of any files specified after
their specification.  Puppet will sometimes use these parameters to check its
own configured state, so they can be used to make Puppet a bit more self-managing.

The file format supports octothorpe-commented lines, but not partial-line comments.

    The environment to check for the value

  • bypass_interpolation (true, false) (defaults to: false) —

    Whether to skip interpolation

Returns:

#values(environment, section) ⇒ Puppet::Settings::ChainedValues

Retrieve an object that can be used for looking up values of configuration settings.

Parameters:

  • environment (Symbol) —

    The name of the environment in which to lookup

  • section (Symbol) —

    The name of the configuration section in which to lookup

Returns:

#which_configuration_file ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

TODO:

this code duplicates Util::RunMode#which_dir as described in #16637

(#15337) All of the logic to determine the configuration file to use

should be centralized into this method.  The simplified approach is:

  1. If there is an explicit configuration file, use that. (–confdir or –config)

  2. If we’re running as a root process, use the system puppet.conf (usually /etc/puppetlabs/puppet/puppet.conf)

  3. Otherwise, use the user puppet.conf (usually ~/.puppetlabs/etc/puppet/puppet.conf)
