Configuration Parameter Reference

SPECIFYING CONFIGURATION PARAMETERS

On The Command-Line

Every Puppet executable (with the exception of puppetdoc) accepts all of the parameters below, but not all of the arguments make sense for every executable.

I have tried to be as thorough as possible in the descriptions of the arguments, so it should be obvious whether an argument is appropriate or not.

These parameters can be supplied to the executables either as command-line options or in the configuration file. For instance, the command-line invocation below would set the configuration directory to /private/puppet:

$ puppetd --confdir=/private/puppet

Note that boolean options are turned on and off with a slightly different syntax on the command line:

$ puppetd --storeconfigs

$ puppetd --no-storeconfigs

The invocations above will enable and disable, respectively, the storage of the client configuration.

Configuration Files

As mentioned above, the configuration parameters can also be stored in a configuration file, located in the configuration directory. As root, the default configuration directory is /etc/puppet, and as a regular user, the default configuration directory is ~user/.puppet. As of 0.23.0, all executables look for puppet.conf in their configuration directory (although they previously looked for separate files). For example, puppet.conf is located at /etc/puppet/puppet.conf as root and ~user/.puppet/puppet.conf as a regular user by default.

All executables will set any parameters set within the main section, while each executable will also look for a section named for the executable and load those parameters. For example, puppetd will look for a section named puppetd, and puppetmasterd looks for a section named puppetmasterd. This allows you to use a single configuration file to customize the settings for all of your executables.

File Format

The file follows INI-style formatting. Here is an example of a very simple puppet.conf file:

[main]
    confdir = /private/puppet
    storeconfigs = true

Note that boolean parameters must be explicitly specified as true or false as seen above.

If you need to change file parameters (e.g., reset the mode or owner), do so within curly braces on the same line:

[main]
    myfile = /tmp/whatever {owner = root, mode = 644}

If youaqre starting out with a fresh configuration, you may wish to let the executable generate a template configuration file for you by invoking the executable in question with the --genconfig command. The executable will print a template configuration to standard output, which can be redirected to a file like so:

$ puppetd --genconfig > /etc/puppet/puppet.conf

Note that this invocation will replace the contents of any pre-existing puppet.conf file, so make a backup of your present config if it contains valuable information.

Like the --genconfig argument, the executables also accept a --genmanifest argument, which will generate a manifest that can be used to manage all of Puppetaqs directories and files and prints it to standard output. This can likewise be redirected to a file:

$ puppetd --genmanifest > /etc/puppet/manifests/site.pp

Puppet can also create user and group accounts for itself (one puppet group and one puppet user) if it is invoked as root with the --mkusers argument:

$ puppetd --mkusers

SIGNALS

The puppetd and puppetmasterd executables catch some signals for special handling. Both daemons catch (SIGHUP), which forces the server to restart tself. Predictably, interrupt and terminate (SIGINT and SIGTERM) will shut down the server, whether it be an instance of puppetd or puppetmasterd.

Sending the SIGUSR1 signal to an instance of puppetd will cause it to immediately begin a new configuration transaction with the server. This signal has no effect on puppetmasterd.

CONFIGURATION PARAMETER REFERENCE

Below is a list of all documented parameters. Not all of them are valid with all Puppet executables, but the executables will ignore any inappropriate values.

async_storeconfigs

Whether to use a queueing system to provide asynchronous database integration. Requires that puppetqd be running and that aqPSONaq support for ruby be installed.

*

Default: false

authconfig

The configuration file that defines the rights to the different namespaces and methods. This can be used as a coarse-grained authorization system for both puppetd and puppetmasterd.

*

Default: $confdir/namespaceauth.conf

autoflush

Whether log files should always flush to disk.

*

Default: false

autosign

Whether to enable autosign. Valid values are true (which autosigns any key request, and is a very bad idea), false (which never autosigns any key request), and the path to a file, which uses that configuration file to determine which keys to sign.

*

Default: $confdir/autosign.conf

bindaddress

The address a listening server should bind to. Mongrel servers default to 127.0.0.1 and WEBrick defaults to 0.0.0.0.

Default: $server

ca_ttl

The default TTL for new certificates; valid values must be an integer, optionally followed by one of the units aqyaq (years of 365 days), aqdaq (days), aqhaq (hours), or aqsaq (seconds). The unit defaults to seconds. If this parameter is set, ca_days is ignored. Examples are aq3600aq (one hour) and aq1825daq, which is the same as aq5yaq (5 years)

*

Default: 5y

cacert

Where to get node catalogs. This is useful to change if, for instance, youaqd like to pre-compile catalogs and store them in memcached or some other easily-accessed store.

*

Default: compiler

A Complete listing of all certificates

*

Default: $cadir/inventory.txt

certdir

certname

The name to use when handling certificates. Defaults to the fully qualified domain name.

*

Default: pelin.lovedthanlost.net

classfile

Where FileBucket files are stored locally.

*

Default: $vardir/clientbucket

clientyamldir

The directory in which client-side YAML data is stored.

*

Default: $vardir/client_yaml

code

*

Default: ansi

confdir

The main Puppet configuration directory. The default for this parameter is calculated based on the user. If the process is runnig as root or the user that puppetmasterd is supposed to run as, it defaults to a system directory, but if itaqs running as any other user, it defaults to being in ~.

*

Default: /etc/puppet

config

The configuration file for puppetdoc.

*

Default: $confdir/puppet.conf

config_version

How to determine the configuration version. By default, it will be the time that the configuration is parsed, but you can provide a shell script to override how the version is determined. The output of this script will be added to every log message in the reports, allowing you to correlate changes on your hosts to the source version on the server.

configprint

Print the value of a specific configuration parameter. If a parameter is provided for this, then the value is printed and puppet exits. Comma-separate multiple values. For a list of all values, specify aqallaq. This feature is only available in Puppet versions higher than 0.18.4.

configtimeout

Facts that are dynamic; these facts will be ignored when deciding whether changed facts should result in a recompile. Multiple facts should be comma-separated.

*

Default: memorysize,memoryfree,swapsize,swapfree

environment

The environment Puppet is running in. For clients (e.g., puppetd) this determines the environment itself, which is used to find modules and much more. For servers (i.e., puppetmasterd) this provides the default environment for nodes we know nothing about.

*

Default: production

evaltrace

Whether each resource should log when it is being evaluated. This allows you to interactively see exactly what is being done.

*

Default: false

external_nodes

An external command that can produce node information. The output must be a YAML dump of a hash, and that hash must have one or both of classes and parameters, where classes is an array and parameters is a hash. For unknown nodes, the commands should exit with a non-zero exit code. This command makes it straightforward to store your node mapping information in other data sources like databases.

*

Default: false

fileserverconfig

Where the fileserver configuration is stored.

The HTTP proxy port to use for outgoing connections

*

Default: 3128

httplog

Where the puppetd web server logs.

*

Default: $logdir/http.log

Ignore cache and always recompile the configuration. This is useful for testing new configurations, where the local cache may in fact be stale even if the timestamps are up to date - if the facts change or if the server changes.

*

Default: false

ignoreimport

A parameter that can be used in commit hooks, since it enables you to parse-check a single file rather than requiring that all files exist.

*

Default: false

ignoreschedules

Boolean; whether puppetd should ignore schedules. This is useful for initial puppetd runs.

*

Default: false

keylength

The bit length of keys.

*

Default: puppetvar

ldapstring

The search string used to find an LDAP node.

*

Default: (&(objectclass=puppetClient)(cn=%s))

ldaptls

Whether TLS should be used when searching for nodes. Defaults to false because TLS usually requires certificates to be set up on the client side.

Default: false

ldapuser

The user to use to connect to LDAP. Must be specified as a full DN.

lexical

Whether to use lexical scoping (vs. dynamic).

*

Default: false

*

Default: $logdir/puppetmaster.log

masterport

Which port puppetmasterd listens on.

*

Default: 8140

maximum_uid

The maximum allowed UID. Some platforms use negative UIDs but then ship with tools that do not know how to handle signed ints, so the UIDs show up as huge numbers that can then not be fed back into the system. This is a hackish way to fail in a slightly more useful way when that happens.

*

Default: 4294967290

mkusers

Whether to create the necessary user and group that puppetd will run as.

*

Default: false

modulepath

The search path for modules as a colon-separated list of directories.

*

Default: HTTP_X_CLIENT_DN

ssl_client_verify_header

The header containing the status message of the client verification. Only used with Mongrel. This header must be set by the proxy to aqSUCCESSaq if the client successfully authenticated, and anything else otherwise. See http://puppetlabs.com/puppet/trac/wiki/UsingMongrel for more information.

*

Default: HTTP_X_CLIENT_VERIFY

*

Default: false

summarize

Whether to print a transaction summary.

Where Puppet looks for template files. Can be a list of colon-seperated directories.

*

Default: $vardir/templates

thin_storeconfigs

Boolean; wether storeconfigs store in the database only the facts and exported resources. If true, then storeconfigs performance will be higher and still allow exported/collected resources, but other usage external to Puppet might not work

trace

Whether to print stack traces on some errors

*

Default: false

typecheck

Whether to validate types during parsing.

*

Default: true

use_cached_catalog

Whether to only use the cached catalog rather than compiling a new catalog on every run. Puppet can be run with this enabled by default and then selectively disabled when a recompile is desired.

*

Default: false

usecacheonfailure

Whether to use the cached configuration when the remote configuration will not compile. This option is useful for testing new configurations, where you want to fix the broken configuration rather than reverting to a known-good one.

*

Default: true

user

The user puppetmasterd should run as.

*

Default: puppet

vardir

Where Puppet stores dynamic and growing data. The default for this parameter is calculated specially, like confdir.
