#app_defaults ⇒ Object

Sets up the ‘node_cache_terminus’ default to use the Write Only Yaml terminus :write_only_yaml. If this is not wanted, the setting ´node_cache_terminus´ should be set to nil.

  <<-'HELP'

puppet-master(8) -- The puppet master daemon
========

SYNOPSIS
--------
The central puppet server. Functions as a certificate authority by
default.


USAGE
-----
puppet master [-D|--daemonize|--no-daemonize] [-d|--debug] [-h|--help]
[-l|--logdest syslog|<FILE>|console] [-v|--verbose] [-V|--version]
[--compile <NODE-NAME>]


DESCRIPTION
-----------
This command starts an instance of puppet master, running as a daemon
and using Ruby's built-in Webrick webserver. Puppet master can also be
managed by other application servers; when this is the case, this
executable is not used.


OPTIONS
-------

Note that any Puppet setting that's valid in the configuration file is also a
valid long argument. For example, 'server' is a valid setting, so you can
specify '--server <servername>' as an argument. Boolean settings translate into
'--setting' and '--no-setting' pairs.

See the configuration file documentation at
http://docs.puppetlabs.com/references/stable/configuration.html for the
full list of acceptable settings. A commented list of all settings can also be
generated by running puppet master with '--genconfig'.

* --daemonize:
Send the process into the background. This is the default.
(This is a Puppet setting, and can go in puppet.conf. Note the special 'no-'
prefix for boolean settings on the command line.)

* --no-daemonize:
Do not send the process into the background.
(This is a Puppet setting, and can go in puppet.conf. Note the special 'no-'
prefix for boolean settings on the command line.)

* --debug:
Enable full debugging.

* --help:
Print this help message.

* --logdest:
Where to send log messages. Choose between 'syslog' (the POSIX syslog
service), 'console', or the path to a log file. If debugging or verbosity is
enabled, this defaults to 'console'. Otherwise, it defaults to 'syslog'.

* --masterport:
The port on which to listen for traffic.
(This is a Puppet setting, and can go in puppet.conf.)

* --verbose:
Enable verbosity.

* --version:
Print the puppet version number and exit.

* --compile:
Compile a catalogue and output it in JSON from the puppet master. Uses
facts contained in the $vardir/yaml/ directory to compile the catalog.


EXAMPLE
-------
puppet master

DIAGNOSTICS
-----------

When running as a standalone daemon, puppet master accepts the
following signals:

* SIGHUP:
Restart the puppet master server.
* SIGINT and SIGTERM:
Shut down the puppet master server.
* SIGUSR2:
Close file descriptors for log files and reopen them. Used with logrotate.

#setup_node_cache ⇒ void

This method returns an undefined value.

Sets up a special node cache “write only yaml” that collects and stores node data in yaml but never finds or reads anything (this since a real cache causes stale data to be served in circumstances when the cache can not be cleared).
