puppet-apply(8) -- Apply Puppet manifests locally
========

SYNOPSIS
--------
Applies a standalone Puppet manifest to the local system.


USAGE
-----
puppet apply [-h|--help] [-V|--version] [-d|--debug] [-v|--verbose]
  [-e|--execute] [--detailed-exitcodes] [-L|--loadclasses]
  [-l|--logdest syslog|eventlog|<FILE>|console] [--noop]
  [--catalog <catalog>] [--write-catalog-summary] <file>


DESCRIPTION
-----------
This is the standalone puppet execution tool; use it to apply
individual manifests.

When provided with a modulepath, via command line or config file, puppet
apply can effectively mimic the catalog that would be served by puppet
master with access to the same modules, although there are some subtle
differences. When combined with scheduling and an automated system for
pushing manifests, this can be used to implement a serverless Puppet
site.

Most users should use 'puppet agent' and 'puppet master' for site-wide
manifests.


OPTIONS
-------
Note that any setting that's valid in the configuration
file is also a valid long argument. For example, 'tags' is a
valid setting, so you can specify '--tags <class>,<tag>'
as an argument.

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

* --debug:
  Enable full debugging.

* --detailed-exitcodes:
  Provide transaction information via exit codes. If this is enabled, an exit
  code of '2' means there were changes, an exit code of '4' means there were
  failures during the transaction, and an exit code of '6' means there were both
  changes and failures.

* --help:
  Print this help message

* --loadclasses:
  Load any stored classes. 'puppet agent' caches configured classes
  (usually at /etc/puppet/classes.txt), and setting this option causes
  all of those classes to be set in your puppet manifest.

* --logdest:
  Where to send log messages. Choose between 'syslog' (the POSIX syslog
  service), 'eventlog' (the Windows Event Log), 'console', or the path to a log
  file. Defaults to 'console'.

  A path ending with '.json' will receive structured output in JSON format. The
  log file will not have an ending ']' automatically written to it due to the
  appending nature of logging. It must be appended manually to make the content
  valid JSON.

* --noop:
  Use 'noop' mode where Puppet runs in a no-op or dry-run mode. This
  is useful for seeing what changes Puppet will make without actually
  executing the changes.

* --execute:
  Execute a specific piece of Puppet code

* --test:
  Enable the most common options used for testing. These are 'verbose',
  'detailed-exitcodes' and 'show_diff'.

* --verbose:
  Print extra information.

* --catalog:
  Apply a JSON catalog (such as one generated with 'puppet master --compile'). You can
  either specify a JSON file or pipe in JSON from standard input.

* --write-catalog-summary
  After compiling the catalog saves the resource list and classes list to the node
  in the state directory named classes.txt and resources.txt

EXAMPLE
-------
    $ puppet apply -l /tmp/manifest.log manifest.pp
    $ puppet apply --modulepath=/root/dev/modules -e "include ntpd::server"
    $ puppet apply --catalog catalog.json
