puppet-device(8) -- #{summary}
========

SYNOPSIS
--------
Retrieves catalogs from the Puppet master and applies them to remote devices. 

This subcommand can be run manually; or periodically using cron,
a scheduled task, or a similar tool.


USAGE
-----
  puppet device [-d|--debug] [--detailed-exitcodes] [--deviceconfig <file>]
            [-h|--help] [-l|--logdest syslog|<file>|console]
            [-v|--verbose] [-w|--waitforcert <seconds>]
            [-t|--target <device>] [--user=<user>] [-V|--version]


DESCRIPTION
-----------
Devices require a proxy Puppet agent to request certificates, collect facts,
retrieve and apply catalogs, and store reports.


USAGE NOTES
-----------
Devices managed by the puppet-device subcommand on a Puppet agent are 
configured in device.conf, which is located at $confdir/device.conf by default, 
and is configurable with the $deviceconfig setting. 

The device.conf file is an INI-like file, with one section per device:

[<DEVICE_CERTNAME>]
type <TYPE>
url <URL>
debug

The section name specifies the certname of the device. 

The values for the type and url properties are specific to each type of device.

The optional debug property specifies transport-level debugging,
and is limited to telnet and ssh transports.

See https://docs.puppet.com/puppet/latest/config_file_device.html for details.


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

* --debug:
  Enable full debugging.

* --detailed-exitcodes:
  Provide transaction information via exit codes. If this is enabled, an exit
  code of '1' means at least one device had a compile failure, an exit code of
  '2' means at least one device had resource changes, and an exit code of '4'
  means at least one device had resource failures. Exit codes of '3', '5', '6',
  or '7' means that a bitwise combination of the preceding exit codes happened.

* --deviceconfig:
  Path to the device config file for puppet device.
  Default: $confdir/device.conf

* --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'.

  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.

* --target:
  Target a specific device/certificate in the device.conf. Doing so will perform a
  device run against only that device/certificate.

* --user:
  The user to run as. '--user=root' is required, even when run as root,
  for runs that create device certificates or keys.

* --verbose:
  Turn on verbose reporting.

* --waitforcert:
  This option only matters for daemons that do not yet have certificates
  and it is enabled by default, with a value of 120 (seconds).  This causes
  +puppet agent+ to connect to the server every 2 minutes and ask it to sign a
  certificate request.  This is useful for the initial setup of a puppet
  client.  You can turn off waiting for certificates by specifying a time of 0.


EXAMPLE
-------
  $ puppet device --server puppet.domain.com
