Configuration Reference

A lock file to indicate that a puppet agent catalog run is currently in progress. The file contains the pid of the process that holds the lock on the catalog run.

• Default: $statedir/agent_catalog_run.lock

A lock file to indicate that puppet agent runs have been administratively disabled. File contains a JSON object with state information.

• Default: $statedir/agent_disabled.lock

Whether to allow a new certificate request to overwrite an existing certificate request. If true, then the old certificate must be cleaned using puppetserver ca clean, and the new request signed using puppetserver ca sign.

• Default: false

Affects how we cache attempts to load Puppet resource types and features. If true, then calls to Puppet.type.<type>? Puppet.feature.<feature>? will always attempt to load the type or feature (which can be an expensive operation) unless it has already been loaded successfully. This makes it possible for a single agent run to, e.g., install a package that provides the underlying capabilities for a type or feature, and then later load that type or feature during the same run (even if the type or feature had been tested earlier and had not been available).

If this setting is set to false, then types and features will only be checked once, and if they are not available, the negative result is cached and returned for all subsequent attempts to load the type or feature. This behavior is almost always appropriate for the server, and can result in a significant performance improvement for types and features that are checked frequently.

• Default: true

Whether log files should always flush to disk.

• Default: true

Whether (and how) to autosign certificate requests. This setting is only relevant on a Puppet Server acting as a certificate authority (CA).

Valid values are true (autosigns all certificate requests; not recommended), false (disables autosigning certificates), or the absolute path to a file.

The file specified in this setting may be either a configuration file or a custom policy executable. Puppet will automatically determine what it is: If the Puppet user (see the user setting) can execute the file, it will be treated as a policy executable; otherwise, it will be treated as a config file.

If a custom policy executable is configured, the CA Puppet Server will run it every time it receives a CSR. The executable will be passed the subject CN of the request as a command line argument, and the contents of the CSR in PEM format on stdin. It should exit with a status of 0 if the cert should be autosigned and non-zero if the cert should not be autosigned.

If a certificate request is not autosigned, it will persist for review. An admin user can use the puppetserver ca sign command to manually sign it, or can delete the request.

For info on autosign configuration files, see the guide to Puppet's config files.

• Default: $confdir/autosign.conf

The search path for global modules. Should be specified as a list of directories separated by the system path separator character. (The POSIX path separator is ':', and the Windows path separator is ';'.)

These are the modules that will be used by all environments. Note that the modules directory of the active environment will have priority over any global directories. For more info, see https://puppet.com/docs/puppet/latest/environments_about.html

• Default: $codedir/modules:/opt/puppetlabs/puppet/modules

The binder configuration file. Puppet reads this file on each request to configure the bindings system. If set to nil (the default), a $confdir/binder_config.yaml is optionally loaded. If it does not exists, a default configuration is used. If the setting :binding_config is specified, it must reference a valid and existing yaml file.

• Default: ``

Where FileBucket files are stored.

• Default: $vardir/bucket

The expected fingerprint of the CA certificate. If specified, the agent will compare the CA certificate fingerprint that it downloads against this value and reject the CA certificate if the values do not match. This only applies during the first download of the CA certificate.

• Default: ``

The name to use the Certificate Authority certificate.

• Default: Puppet CA: $certname

The port to use for the certificate authority.

• Default: $serverport

The server to use for certificate authority requests. It's a separate server because it cannot and does not need to horizontally scale.

• Default: $server

The default TTL for new certificates. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 5y

The CA certificate.

• Default: $cadir/ca_crt.pem

The certificate revocation list (CRL) for the CA.

• Default: $cadir/ca_crl.pem

The root directory for the certificate authority.

• Default: /etc/puppetlabs/puppetserver/ca

The CA private key.

• Default: $cadir/ca_key.pem

The CA public key.

• Default: $cadir/ca_pub.pem

How to store cached catalogs. Valid values are 'json', 'msgpack' and 'yaml'. The agent application defaults to 'json'.

• Default: ``

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

• Default: compiler

The inventory file. This is a text file to which the CA writes a complete listing of all certificates.

• Default: $cadir/inventory.txt

The certificate directory.

• Default: $ssldir/certs

Whether certificate revocation checking should be enabled, and what level of checking should be performed.

When certificate revocation is enabled, Puppet expects the contents of its CRL to be one or more PEM-encoded CRLs concatenated together. When using a cert bundle, CRLs for all CAs in the chain of trust must be included in the crl file. The chain should be ordered from least to most authoritative, with the first CRL listed being for the root of the chain and the last being for the leaf CA.

When certificate_revocation is set to 'true' or 'chain', Puppet ensures that each CA in the chain of trust has not been revoked by its issuing CA.

When certificate_revocation is set to 'leaf', Puppet verifies certs against the issuing CA's revocation list, but it does not verify the revocation status of the issuing CA or any CA above it within the chain of trust.

When certificate_revocation is set to 'false', Puppet disables all certificate revocation checking and does not attempt to download the CRL.

• Default: chain

The name to use when handling certificates. When a node requests a certificate from the CA Puppet Server, it uses the value of the certname setting as its requested Subject CN.

This is the name used when managing a node's permissions in Puppet Server's auth.conf. In most cases, it is also used as the node's name when matching node definitions and requesting data from an ENC. (This can be changed with the node_name_value and node_name_fact settings, although you should only do so if you have a compelling reason.)

A node's certname is available in Puppet manifests as $trusted['certname']. (See Facts and Built-In Variables for more details.)

• For best compatibility, you should limit the value of certname to only use lowercase letters, numbers, periods, underscores, and dashes. (That is, it should match /A[a-z0-9._-]+Z/.)

• The special value ca is reserved, and can't be used as the certname for a normal node.

  Note: You must set the certname in the main section of the puppet.conf file. Setting it in a different section causes errors.

Defaults to the node's fully qualified domain name.

• Default: the Host's fully qualified domain name, as determined by Facter

The list of ciphersuites for TLS connections initiated by puppet. The default value is chosen to support TLS 1.0 and up, but can be made more restrictive if needed. The ciphersuites must be specified in OpenSSL format, not IANA.

• Default: ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA256:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256

The file in which puppet agent stores a list of the classes associated with the retrieved configuration. Can be loaded in the separate puppet executable using the --loadclasses option.

• Default: $statedir/classes.txt

The directory in which serialized data is stored on the client.

• Default: $vardir/client_data

Where FileBucket files are stored locally.

• Default: $vardir/clientbucket

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

• Default: $vardir/client_yaml

Code to parse directly. This is essentially only used by puppet, and should only be set if you're writing your own Puppet executable.

The main Puppet code directory. The default for this setting is calculated based on the user. If the process is running as root or the user that Puppet is supposed to run as, it defaults to a system directory, but if it's running as any other user, it defaults to being in the user's home directory.

• Default: Unix/Linux: /etc/puppetlabs/code -- Windows: C:\ProgramData\PuppetLabs\code -- Non-root user: ~/.puppetlabs/etc/code

Whether to use colors when logging to the console. Valid values are ansi (equivalent to true), html, and false, which produces no color.

• Default: ansi

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

• Default: Unix/Linux: /etc/puppetlabs/puppet -- Windows: C:\ProgramData\PuppetLabs\puppet\etc -- Non-root user: ~/.puppetlabs/etc/puppet

The configuration file for the current puppet application.

• Default: $confdir/${config_file_name}

The name of the puppet config file.

• Default: puppet.conf

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.

Setting a global value for config_version in puppet.conf is not allowed (but it can be overridden from the commandline). Please set a per-environment value in environment.conf instead. For more info, see https://puppet.com/docs/puppet/latest/environments_about.html

Prints the value of a specific configuration setting. If the name of a setting is provided for this, then the value is printed and puppet exits. Comma-separate multiple values. For a list of all values, specify 'all'. This setting is deprecated, the 'puppet config' command replaces this functionality.

How often the Puppet agent refreshes its local CRL. By default the CRL is only downloaded once, and never refreshed. If a duration is specified, then the agent will refresh its CRL whenever it next runs and the elapsed time since the CRL was last refreshed exceeds the duration.

In general, the duration should be greater than the runinterval. Setting it to an equal or lesser value will cause the CRL to be refreshed on every run.

If the agent downloads a new CRL, the agent will use it for subsequent network requests. If the refresh request fails or if the CRL is unchanged on the server, then the agent run will continue using the local CRL it already has.This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: ``

An optional file containing custom attributes to add to certificate signing requests (CSRs). You should ensure that this file does not exist on your CA Puppet Server; if it does, unwanted certificate extensions may leak into certificates created with the puppetserver ca generate command.

If present, this file must be a YAML hash containing a custom_attributes key and/or an extension_requests key. The value of each key must be a hash, where each key is a valid OID and each value is an object that can be cast to a string.

Custom attributes can be used by the CA when deciding whether to sign the certificate, but are then discarded. Attribute OIDs can be any OID value except the standard CSR attributes (i.e. attributes described in RFC 2985 section 5.4). This is useful for embedding a pre-shared key for autosigning policy executables (see the autosign setting), often by using the 1.2.840.113549.1.9.7 ("challenge password") OID.

Extension requests will be permanently embedded in the final certificate. Extension OIDs must be in the "ppRegCertExt" (1.3.6.1.4.1.34380.1.1), "ppPrivCertExt" (1.3.6.1.4.1.34380.1.2), or "ppAuthCertExt" (1.3.6.1.4.1.34380.1.3) OID arcs. The ppRegCertExt arc is reserved for four of the most common pieces of data to embed: pp_uuid (.1), pp_instance_id (.2), pp_image_name (.3), and pp_preshared_key (.4) --- in the YAML file, these can be referred to by their short descriptive names instead of their full OID. The ppPrivCertExt arc is unregulated, and can be used for site-specific extensions. The ppAuthCert arc is reserved for two pieces of data to embed: pp_authorization (.1) and pp_auth_role (.13). As with ppRegCertExt, in the YAML file, these can be referred to by their short descriptive name instead of their full OID.

• Default: $confdir/csr_attributes.yaml

Where the CA stores certificate requests.

• Default: $cadir/requests

Whether to send the process into the background. This defaults to true on POSIX systems, and to false on Windows (where Puppet currently cannot daemonize).

• Default: true

This setting has been deprecated. Use of any value other than 'hiera' should instead be configured in a version 5 hiera.yaml. Until this setting is removed, it controls which data binding terminus to use for global automatic data binding (across all environments). By default this value is 'hiera'. A value of 'none' turns off the global binding.

• Default: hiera

The default source for files if no server is given in a uri, e.g. puppet:///file. The default of rest causes the file to be retrieved using the server setting. When running apply the default is file_server, causing requests to be filled locally.

• Default: rest

The default main manifest for directory environments. Any environment that doesn't set the manifest setting in its environment.conf file will use this manifest.

This setting's value can be an absolute or relative path. An absolute path will make all environments default to the same main manifest; a relative path will allow each environment to use its own manifest, and Puppet will resolve the path relative to each environment's main directory.

In either case, the path can point to a single file or to a directory of manifests to be evaluated in alphabetical order.

• Default: ./manifests

Boolean; whether to generate the default schedule resources. Setting this to false is useful for keeping external report processors clean of skipped schedule resources.

• Default: true

The root directory of devices' $confdir.

• Default: $confdir/devices

Path to the device config file for puppet device.

• Default: $confdir/device.conf

The root directory of devices' $vardir.

• Default: $vardir/devices

Which diff command to use when printing differences between files. This setting has no default value on Windows, as standard diff is not available, but Puppet can use many third-party diff tools.

• Default: diff

Which arguments to pass to the diff command when printing differences between files. The command to use can be chosen with the diff setting.

• Default: -u

Which digest algorithm to use for file resources and the filebucket. Valid values are sha256, sha384, sha512, sha224, md5. Default is sha256.

• Default: sha256

If true, turns off all translations of Puppet and module log messages, which affects error, warning, and info log messages, as well as any translations in the report and CLI.

• Default: true

Whether to disallow an environment-specific main manifest. When set to true, Puppet will use the manifest specified in the default_manifest setting for all environments. If an environment specifies a different main manifest in its environment.conf file, catalog requests for that environment will fail with an error.

This setting requires default_manifest to be set to an absolute path.

• Default: false

A comma-separated list of warning types to suppress. If large numbers of warnings are making Puppet's logs too large or difficult to use, you can temporarily silence them with this setting.

If you are preparing to upgrade Puppet to a new major version, you should re-enable all warnings for a while.

Valid values for this setting are:

• deprecations --- disables deprecation warnings.

• undefined_variables --- disables warnings about non existing variables.

• undefined_resources --- disables warnings about non existing resources.

• Default: []

A comma-separated list of alternate DNS names for Puppet Server. These are extra hostnames (in addition to its certname) that the server is allowed to use when serving agents. Puppet checks this setting when automatically creating a certificate for Puppet agent or Puppet Server. These can be either IP or DNS, and the type should be specified and followed with a colon. Untyped inputs will default to DNS.

In order to handle agent requests at a given hostname (like "puppet.example.com"), Puppet Server needs a certificate that proves it's allowed to use that name; if a server shows a certificate that doesn't include its hostname, Puppet agents will refuse to trust it. If you use a single hostname for Puppet traffic but load-balance it to multiple Puppet Servers, each of those servers needs to include the official hostname in its list of extra names.

Note: The list of alternate names is locked in when the server's certificate is signed. If you need to change the list later, you can't just change this setting; you also need to regenerate the certificate. For more information on that process, see the cert regen docs.

To see all the alternate names your servers are using, log into your CA server and run puppetserver ca list --all, then check the output for (alt names: ...). Most agent nodes should NOT have alternate names; the only certs that should have them are Puppet Server nodes that you want other agents to trust.

Whether to document all resources when using puppet doc to generate manifest documentation.

• Default: false

The environment in which Puppet is running. For clients, such as puppet agent, this determines the environment itself, which Puppet uses to find modules and much more. For servers, such as puppet server, this provides the default environment for nodes that Puppet knows nothing about.

When defining an environment in the [agent] section, this refers to the environment that the agent requests from the primary server. The environment doesn't have to exist on the local filesystem because the agent fetches it from the primary server. This definition is used when running puppet agent.

When defined in the [user] section, the environment refers to the path that Puppet uses to search for code and modules related to its execution. This requires the environment to exist locally on the filesystem where puppet is being executed. Puppet subcommands, including puppet module and puppet apply, use this definition.

Given that the context and effects vary depending on the config section in which the environment setting is defined, do not set it globally.

• Default: production

The name of a registered environment data provider used when obtaining environment specific data. The three built in and registered providers are 'none' (no data), 'function' (data obtained by calling the function 'environment::data()') and 'hiera' (data obtained using a data provider configured using a hiera.yaml file in root of the environment). Other environment data providers may be registered in modules on the module path. For such custom data providers see the respective module documentation. This setting is deprecated.

• Default: ``

How long the Puppet server should cache data it loads from an environment.

A value of 0 will disable caching. This setting can also be set to unlimited, which will cache environments until the server is restarted or told to refresh the cache. All other values will result in Puppet server evicting environments that haven't been used within the last environment_timeout seconds.

You should change this setting once your Puppet deployment is doing non-trivial work. We chose the default value of 0 because it lets new users update their code without any extra steps, but it lowers the performance of your Puppet server. We recommend either:

• Setting this to unlimited and explicitly refreshing your Puppet server as part of your code deployment process.

• Setting this to a number that will keep your most actively used environments cached, but allow testing environments to fall out of the cache and reduce memory usage. A value of 3 minutes (3m) is a reasonable value.

Once you set environment_timeout to a non-zero value, you need to tell Puppet server to read new code from disk using the environment-cache API endpoint after you deploy new code. See the docs for the Puppet Server administrative API.

• Default: 0

A search path for directory environments, as a list of directories separated by the system path separator character. (The POSIX path separator is ':', and the Windows path separator is ';'.)

This setting must have a value set to enable directory environments. The recommended value is $codedir/environments. For more details, see https://puppet.com/docs/puppet/latest/environments_about.html

• Default: $codedir/environments

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

• Default: false

Whether to omit data about unchanged resources from reports. This can decrease the size of reports significantly.

• Default: false

The external node classifier (ENC) script to use for node data. Puppet combines this data with the main manifest to produce node catalogs.

To enable this setting, set the node_terminus setting to exec.

This setting's value must be the path to an executable command that can produce node information. The command must:

• Take the name of a node as a command-line argument.

• Return a YAML hash with up to three keys:

  • classes --- A list of classes, as an array or hash.

  • environment --- A string.

  • parameters --- A list of top-scope variables to set, as a hash.

• For unknown nodes, exit with a non-zero exit code.

Generally, an ENC script makes requests to an external data source.

For more info, see the ENC documentation.

• Default: none

The soft limit for the length of a fact name.

• Default: 2560

The soft limit for the length of a fact value.

• Default: 4096

Where Puppet should look for facts. Multiple directories should be separated by the system path separator character. (The POSIX path separator is ':', and the Windows path separator is ';'.)

• Default: $vardir/lib/facter:$vardir/facts

The node facts terminus.

• Default: facter

Where the fileserver configuration is stored.

• Default: $confdir/fileserver.conf

The minimum time to wait between checking for updates in configuration files. This timeout determines how quickly Puppet checks whether a file (such as manifests or puppet.conf) has changed on disk. The default will change in a future release to be 'unlimited', requiring a reload of the Puppet service to pick up changes to its internal configuration. Currently we do not accept a value of 'unlimited'. To reparse files within an environment in Puppet Server please use the environment_cache endpoint

• Default: 15s

The authorization key to connect to the Puppet Forge. Leave blank for unauthorized or license based connections

• Default: ``

Freezes the 'main' class, disallowing any code to be added to it. This essentially means that you can't have any code outside of a node, class, or definition other than in the site manifest.

• Default: false

When true, causes Puppet applications to print an example config file to stdout and exit. The example will include descriptions of each setting, and the current (or default) value of each setting, incorporating any settings overridden on the CLI (with the exception of genconfig itself). This setting only makes sense when specified on the command line as --genconfig.

• Default: false

Whether to just print a manifest to stdout and exit. Only makes sense when specified on the command line as --genmanifest. Takes into account arguments specified on the CLI.

• Default: false

Whether to create .dot graph files, which let you visualize the dependency and containment relationships in Puppet's catalog. You can load and view these files with tools like OmniGraffle (OS X) or graphviz (multi-platform).

Graph files are created when applying a catalog, so this setting should be used on nodes running puppet agent or puppet apply.

The graphdir setting determines where Puppet will save graphs. Note that we don't save graphs for historical runs; Puppet will replace the previous .dot files with new ones every time it applies a catalog.

See your graphing software's documentation for details on opening .dot files. If you're using GraphViz's dot command, you can do a quick PNG render with dot -Tpng <DOT FILE> -o <OUTPUT FILE>.

• Default: false

Where to save .dot-format graphs (when the graph setting is enabled).

• Default: $statedir/graphs

The group Puppet Server will run as. Used to ensure the agent side processes (agent, apply, etc) create files and directories readable by Puppet Server when necessary.

• Default: puppet

The hiera configuration file. Puppet only reads this file on startup, so you must restart the puppet server every time you edit it.

• Default: $confdir/hiera.yaml. However, for backwards compatibility, if a file exists at $codedir/hiera.yaml, Puppet uses that instead.

Where individual hosts store and look for their certificates.

• Default: $certdir/$certname.pem

Where the host's certificate revocation list can be found. This is distinct from the certificate authority's CRL.

• Default: $ssldir/crl.pem

Where individual hosts store their certificate request (CSR) while waiting for the CA to issue their certificate.

• Default: $requestdir/$certname.pem

Where individual hosts store and look for their private key.

• Default: $privatekeydir/$certname.pem

Where individual hosts store and look for their public key.

• Default: $publickeydir/$certname.pem

The maximum amount of time to wait when establishing an HTTP connection. The default value is 2 minutes. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 2m

Whether to write HTTP request and responses to stderr. This should never be used in a production environment.

• Default: false

The list of extra headers that will be sent with http requests to the primary server. The header definition consists of a name and a value separated by a colon.

• Default: []

The maximum amount of time a persistent HTTP connection can remain idle in the connection pool, before it is closed. This timeout should be shorter than the keepalive timeout used on the HTTP server, e.g. Apache KeepAliveTimeout directive. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 4s

The HTTP proxy host to use for outgoing connections. The proxy will be bypassed if the server's hostname matches the NO_PROXY environment variable or no_proxy setting. Note: You may need to use a FQDN for the server hostname when using a proxy. Environment variable http_proxy or HTTP_PROXY will override this value.

• Default: none

The password for the user of an authenticated HTTP proxy. Requires the http_proxy_user setting.

Note that passwords must be valid when used as part of a URL. If a password contains any characters with special meanings in URLs (as specified by RFC 3986 section 2.2), they must be URL-encoded. (For example, # would become %23.)

• Default: none

The HTTP proxy port to use for outgoing connections

• Default: 3128

The user name for an authenticated HTTP proxy. Requires the http_proxy_host setting.

• Default: none

The time to wait for data to be read from an HTTP connection. If nothing is read after the elapsed interval then the connection will be closed. The default value is 10 minutes. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 10m

The HTTP User-Agent string to send when making network requests.

• Default: Puppet/7.14.0 Ruby/2.6.3-p62 (x86_64-darwin19)

Whether the puppet run should ignore errors during pluginsync. If the setting is false and there are errors during pluginsync, then the agent will abort the run and submit a report containing information about the failed run.

• Default: false

Skip searching for classes and definitions that were missing during a prior compilation. The list of missing objects is maintained per-environment and persists until the environment is cleared or the primary server is restarted.

• Default: false

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

• Default: false

Boolean; whether legacy facts are sent to puppetserver when requesting a catalog.

• Default: true

The type of private key. Valid values are rsa and ec. Default is rsa.

• Default: rsa

The bit length of keys.

• Default: 4096

Where puppet agent stores the last run report summary in yaml format.

• Default: $publicdir/last_run_summary.yaml

Where Puppet Agent stores the last run report, by default, in yaml format. The format of the report can be changed by setting the cache key of the report terminus in the routes.yaml file. To avoid mismatches between content and file extension, this setting needs to be manually updated to reflect the terminus changes.

• Default: $statedir/last_run_report.yaml

The LDAP attributes to include when querying LDAP for nodes. All returned attributes are set as variables in the top-level scope. Multiple values should be comma-separated. The value 'all' returns all attributes.

• Default: all

The search base for LDAP searches. It's impossible to provide a meaningful default here, although the LDAP libraries might have one already set. Generally, it should be the 'ou=Hosts' branch under your main directory.

The LDAP attributes to use to define Puppet classes. Values should be comma-separated.

• Default: puppetclass

The attribute to use to define the parent node.

• Default: parentnode

The password to use to connect to LDAP.

The LDAP port.

• Default: 389

The LDAP server.

• Default: ldap

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

• Default: false

The LDAP attributes that should be stacked to arrays by adding the values in all hierarchy elements of the tree. Values should be comma-separated.

• Default: puppetvar

The search string used to find an LDAP node.

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

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

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

An extra search path for Puppet. This is only useful for those files that Puppet will load on demand, and is only guaranteed to work for those cases. In fact, the autoload mechanism is responsible for making sure this directory is in Ruby's search path

• Default: $vardir/lib

Where each client stores the CA certificate.

• Default: $certdir/ca.pem

Where Puppet should store translation files that it pulls down from the central server.

• Default: $vardir/locales

From where to retrieve translation files. The standard Puppet file type is used for retrieval, so anything that is a valid file source can be used here.

• Default: puppet:///locales

This will allow sending the name + password and the cookie header to all hosts that puppet may redirect to. This may or may not introduce a security breach if puppet redirects you to a site to which you'll send your authentication info and cookies.

• Default: false

Default logging level for messages from Puppet. Allowed values are:

• debug

• info

• notice

• warning

• err

• alert

• emerg

• crit

• Default: notice

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. Multiple destinations can be set using a comma separated list (eg: /path/file1,console,/path/file2)

• Default: ``

The directory in which to store log files

• Default: Unix/Linux: /var/log/puppetlabs/puppet -- Windows: C:\ProgramData\PuppetLabs\puppet\var\log -- Non-root user: ~/.puppetlabs/var/log

Whether Puppet should manage the owner, group, and mode of files it uses internally. Note: For Windows agents, the default is false for versions 4.10.13 and greater, versions 5.5.6 and greater, and versions 6.0 and greater.

• Default: true

The entry-point manifest for the primary server. This can be one file or a directory of manifests to be evaluated in alphabetical order. Puppet manages this path as a directory if one exists or if the path ends with a / or .

Setting a global value for manifest in puppet.conf is not allowed (but it can be overridden from the commandline). Please use directory environments instead. If you need to use something other than the environment's manifests directory as the main manifest, you can set manifest in environment.conf. For more info, see https://puppet.com/docs/puppet/latest/environments_about.html

• Default: ``

The default port puppet subcommands use to communicate with Puppet Server. (eg puppet facts upload, puppet agent). May be overridden by more specific settings (see ca_port, report_port).

• Default: 8140

Sets the max number of logged/displayed parser validation deprecation warnings in case multiple deprecation warnings have been detected. A value of 0 blocks the logging of deprecation warnings. The count is per manifest.

• Default: 10

Sets the max number of logged/displayed parser validation errors in case multiple errors have been detected. A value of 0 is the same as a value of 1; a minimum of one error is always raised. The count is per manifest.

• Default: 10

Sets the max number of logged/displayed parser validation warnings in case multiple warnings have been detected. A value of 0 blocks logging of warnings. The count is per manifest.

• Default: 10

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

The maximum amount of time the Puppet agent should wait for its certificate request to be signed. A value of unlimited will cause puppet agent to ask for a signed certificate indefinitely. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: unlimited

The maximum amount of time the puppet agent should wait for an already running puppet agent to finish before starting a new one. This is set by default to 1 minute. A value of unlimited will cause puppet agent to wait indefinitely. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 1m

Whether to merge class-level dependency failure warnings.

When a class has a failed dependency, every resource in the class generates a notice level message about the dependency failure, and a warning level message about skipping the resource.

If true, all messages caused by a class dependency failure are merged into one message associated with the class.

• Default: false

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

• Default: false

Extra module groups to request from the Puppet Forge. This is an internal setting, and users should never change it.

• Default: ``

The module repository

• Default: https://forgeapi.puppet.com

The directory into which module tool data is stored

• Default: $vardir/puppet-module

The search path for modules, as a list of directories separated by the system path separator character. (The POSIX path separator is ':', and the Windows path separator is ';'.)

Setting a global value for modulepath in puppet.conf is not allowed (but it can be overridden from the commandline). Please use directory environments instead. If you need to use something other than the default modulepath of <ACTIVE ENVIRONMENT'S MODULES DIR>:$basemodulepath, you can set modulepath in environment.conf. For more info, see https://puppet.com/docs/puppet/latest/environments_about.html

The name of the application, if we are running as one. The default is essentially $0 without the path or .rb.

• Default: ``

The short name for the EC curve used to generate the EC private key. Valid values must be one of the curves in OpenSSL::PKey::EC.builtin_curves. Default is prime256v1.

• Default: prime256v1

List of host or domain names that should not go through http_proxy_host. Environment variable no_proxy or NO_PROXY will override this value. Names can be specified as an FQDN host.example.com, wildcard *.example.com, dotted domain .example.com, or suffix example.com.

• Default: localhost, 127.0.0.1

How to store cached nodes. Valid values are (none), 'json', 'msgpack', or 'yaml'.

• Default: ``

The fact name used to determine the node name used for all requests the agent makes to the primary server. WARNING: This setting is mutually exclusive with node_name_value. Changing this setting also requires changes to Puppet Server's default auth.conf.

The explicit value used for the node name for all requests the agent makes to the primary server. WARNING: This setting is mutually exclusive with node_name_fact. Changing this setting also requires changes to Puppet Server's default auth.conf.

• Default: $certname

Which node data plugin to use when compiling node catalogs.

When Puppet compiles a catalog, it combines two primary sources of info: the main manifest, and a node data plugin (often called a "node terminus," for historical reasons). Node data plugins provide three things for a given node name:

1. A list of classes to add to that node's catalog (and, optionally, values for their parameters).

2. Which Puppet environment the node should use.

3. A list of additional top-scope variables to set.

The three main node data plugins are:

• plain --- Returns no data, so that the main manifest controls all node configuration.

• exec --- Uses an external node classifier (ENC), configured by the external_nodes setting. This lets you pull a list of Puppet classes from any external system, using a small glue script to perform the request and format the result as YAML.

• classifier (formerly console) --- Specific to Puppet Enterprise. Uses the PE console for node data."

• Default: plain

Whether to apply catalogs in noop mode, which allows Puppet to partially simulate a normal run. This setting affects puppet agent and puppet apply.

When running in noop mode, Puppet will check whether each resource is in sync, like it does when running normally. However, if a resource attribute is not in the desired state (as declared in the catalog), Puppet will take no action, and will instead report the changes it would have made. These simulated changes will appear in the report sent to the primary Puppet server, or be shown on the console if running puppet agent or puppet apply in the foreground. The simulated changes will not send refresh events to any subscribing or notified resources, although Puppet will log that a refresh event would have been sent.

Important note: The noop metaparameter allows you to apply individual resources in noop mode, and will override the global value of the noop setting. This means a resource with noop => false will be changed if necessary, even when running puppet agent with noop = true or --noop. (Conversely, a resource with noop => true will only be simulated, even when noop mode is globally disabled.)

• Default: false

The soft limit for the total number of facts.

• Default: 2048

Perform one configuration run and exit, rather than spawning a long-running daemon. This is useful for interactively running puppet agent, or running puppet agent from cron.

• Default: false

Where puppet agent stores the password for its private key. Generally unused.

• Default: $privatedir/password

The shell search path. Defaults to whatever is inherited from the parent process.

This setting can only be set in the [main] section of puppet.conf; it cannot be set in [server], [agent], or an environment config section.

• Default: none

The soft limit for the size of the payload.

• Default: 16777216

The file containing the PID of a running process. This file is intended to be used by service management frameworks and monitoring systems to determine if a puppet process is still in the process table.

• Default: $rundir/${run_mode}.pid

Where Puppet should store plugins that it pulls down from the central server.

• Default: $libdir

Where Puppet should store external facts that are being handled by pluginsync

• Default: $vardir/facts.d

Where to retrieve external facts for pluginsync

• Default: puppet:///pluginfacts

What files to ignore when pulling down plugins.

• Default: .svn CVS .git .hg

From where to retrieve plugins. The standard Puppet file type is used for retrieval, so anything that is a valid file source can be used here.

• Default: puppet:///plugins

Whether plugins should be synced with the central server. This setting is deprecated.

• Default: true

A command to run after every agent run. If this command returns a non-zero return code, the entire Puppet run will be considered to have failed, even though it might have performed work during the normal run.

The preferred means of serializing ruby instances for passing over the wire. This won't guarantee that all instances will be serialized using this method, since not all classes can be guaranteed to support this format, but it will be used for all classes that support it.

• Default: json

Whether deferred commands are preprocessed or called on demand. When set to false, other resources in the catalog can serve as inputs to the deferred function. If the deferred function fails, then only that resource fails, while unrelated resources are still applied.

• Default: true

A command to run before every agent run. If this command returns a non-zero return code, the entire Puppet run will fail.

The directory where catalog previews per node are generated.

• Default: $vardir/preview

The scheduling priority of the process. Valid values are 'high', 'normal', 'low', or 'idle', which are mapped to platform-specific values. The priority can also be specified as an integer value and will be passed as is, e.g. -5. Puppet must be running as a privileged user in order to increase scheduling priority.

• Default: ``

Where the client stores private certificate information.

• Default: $ssldir/private

The private key directory.

• Default: $ssldir/private_keys

Whether to enable experimental performance profiling

• Default: false

Where Puppet stores public files.

• Default: Unix/Linux: /opt/puppetlabs/puppet/public -- Windows: C:\ProgramData\PuppetLabs\puppet\public -- Non-root user: ~/.puppetlabs/opt/puppet/public

The public key directory.

• Default: $ssldir/public_keys

Whether to print the Puppet stack trace on some errors. This is a noop if trace is also set.

• Default: false

The fallback log file. This is only used when the --logdest option is not specified AND Puppet is running on an operating system where both the POSIX syslog service and the Windows Event Log are unavailable. (Currently, no supported operating systems match that description.)

Despite the name, both puppet agent and puppet server will use this file as the fallback logging destination.

For control over logging destinations, see the --logdest command line option in the manual pages for puppet server, puppet agent, and puppet apply. You can see man pages by running puppet <SUBCOMMAND> --help, or read them online at https://puppet.com/docs/puppet/latest/man/.

• Default: $logdir/puppetd.log

Whether to send reports after every transaction.

• Default: true

Whether to report the full directory path to the environment before resolving symlinks as the source for resources in a catalog. If set to false, Puppet reports the path to the resource after resolving symlinks.

• Default: true

Whether the 'http' report processor should include the system certificate store when submitting reports to HTTPS URLs. If false, then the 'http' processor will only trust HTTPS report servers whose certificates are issued by the puppet CA or one of its intermediate CAs. If true, the processor will additionally trust CA certificates in the system's certificate store.

• Default: false

The port to communicate with the report_server.

• Default: $serverport

The server to send transaction reports to.

• Default: $server

The directory in which to store reports. Each node gets a separate subdirectory in this directory. This setting is only used when the store report processor is enabled (see the reports setting).

• Default: $vardir/reports

The list of report handlers to use. When using multiple report handlers, their names should be comma-separated, with whitespace allowed. (For example, reports = http, store.)

This setting is relevant to puppet server and puppet apply. The primary Puppet server will call these report handlers with the reports it receives from agent nodes, and puppet apply will call them with its own report. (In all cases, the node applying the catalog must have report = true.)

See the report reference for information on the built-in report handlers; custom report handlers can also be loaded from modules. (Report handlers are loaded from the lib directory, at puppet/reports/NAME.rb.)

To turn off reports entirely, set this to none

• Default: store

The URL that reports should be forwarded to. This setting is only used when the http report processor is enabled (see the reports setting).

• Default: http://localhost:3000/reports/upload

Where host certificate requests are stored.

• Default: $ssldir/certificate_requests

The file in which puppet agent stores a list of the resources associated with the retrieved configuration.

• Default: $statedir/resources.txt

Whether to send updated facts after every transaction. By default puppet only submits facts at the beginning of the transaction before applying a catalog. Since puppet can modify the state of the system, the value of the facts may change after puppet finishes. Therefore, any facts stored in puppetdb may not be consistent until the agent next runs, typically in 30 minutes. If this feature is enabled, puppet will resubmit facts after applying its catalog, ensuring facts for the node stored in puppetdb are current. However, this will double the fact submission load on puppetdb, so it is disabled by default.

• Default: false

Enables having extended data in the catalog by storing them as a hash with the special key __ptype. When enabled, resource containing values of the data types Binary, Regexp, SemVer, SemVerRange, Timespan and Timestamp, as well as instances of types derived from Object retain their data type.

• Default: true

The YAML file containing indirector route configuration.

• Default: $confdir/routes.yaml

Where Puppet PID files are kept.

• Default: Unix/Linux: /var/run/puppetlabs -- Windows: C:\ProgramData\PuppetLabs\puppet\var\run -- Non-root user: ~/.puppetlabs/var/run

How often puppet agent applies the catalog. Note that a runinterval of 0 means "run continuously" rather than "never run." This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 30m

The maximum amount of time an agent run is allowed to take. A Puppet agent run that exceeds this timeout will be aborted. A value of 0 disables the timeout. Defaults to 1 hour. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 1h

Where the serial number for certificates is stored.

• Default: $cadir/serial

The primary Puppet server to which the Puppet agent should connect.

• Default: puppet

The directory in which serialized data is stored, usually in a subdirectory.

• Default: $vardir/server_data

The list of primary Puppet servers to which the Puppet agent should connect, in the order that they will be tried. Each value should be a fully qualified domain name, followed by an optional ':' and port number. If a port is omitted, Puppet uses masterport for that host.

• Default: []

The default port puppet subcommands use to communicate with Puppet Server. (eg puppet facts upload, puppet agent). May be overridden by more specific settings (see ca_port, report_port).

• Default: 8140

Whether to compile and apply the settings catalog

• Default: true

Whether to log and report a contextual diff when files are being replaced. This causes partial file contents to pass through Puppet's normal logging and reporting system, so this setting should be used with caution if you are sending Puppet's reports to an insecure destination. This feature currently requires the diff/lcs Ruby library.

• Default: false

Where the CA stores signed certificates.

• Default: $cadir/signed

Tags to use to filter resources. If this is set, then only resources not tagged with the specified tags will be applied. Values must be comma-separated.

The address the agent should use to initiate requests.

• Default: ``

Whether to sleep for a random amount of time, ranging from immediately up to its $splaylimit, before performing its first agent run after a service restart. After this period, the agent runs periodically on its $runinterval.

For example, assume a default 30-minute $runinterval, splay set to its default of false, and an agent starting at :00 past the hour. The agent would check in every 30 minutes at :01 and :31 past the hour.

With splay enabled, it waits any amount of time up to its $splaylimit before its first run. For example, it might randomly wait 8 minutes, then start its first run at :08 past the hour. With the $runinterval at its default 30 minutes, its next run will be at :38 past the hour.

If you restart an agent's puppet service with splay enabled, it recalculates its splay period and delays its first agent run after restarting for this new period. If you simultaneously restart a group of puppet agents with splay enabled, their checkins to your primary servers can be distributed more evenly.

• Default: false

The maximum time to delay before an agent's first run when splay is enabled. Defaults to the agent's $runinterval. The splay interval is random and recalculated each time the agent is started or restarted. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: $runinterval

The domain which will be queried to find the SRV records of servers to use.

• Default: hoffman-C02Q72LKFVH6

The header containing an authenticated client's SSL DN. This header must be set by the proxy to the authenticated client's SSL DN (e.g., /CN=puppet.puppetlabs.com). Puppet will parse out the Common Name (CN) from the Distinguished Name (DN) and use the value of the CN field for authorization.

Note that the name of the HTTP header gets munged by the web server common gateway interface: an HTTP_ prefix is added, dashes are converted to underscores, and all letters are uppercased. Thus, to use the X-Client-DN header, this setting should be HTTP_X_CLIENT_DN.

• Default: HTTP_X_CLIENT_DN

The header containing the status message of the client verification. This header must be set by the proxy to 'SUCCESS' if the client successfully authenticated, and anything else otherwise.

Note that the name of the HTTP header gets munged by the web server common gateway interface: an HTTP_ prefix is added, dashes are converted to underscores, and all letters are uppercased. Thus, to use the X-Client-Verify header, this setting should be HTTP_X_CLIENT_VERIFY.

• Default: HTTP_X_CLIENT_VERIFY

A lock file to indicate that the ssl bootstrap process is currently in progress.

• Default: $ssldir/ssl.lock

A file containing CA certificates in PEM format that puppet should trust when making HTTPS requests. This only applies to https requests to non-puppet infrastructure, such as retrieving file metadata and content from https file sources, puppet module tool and the 'http' report processor. This setting is ignored when making requests to puppet:// URLs such as catalog and report requests.

• Default: ``

Where SSL certificates are kept.

• Default: $confdir/ssl

The directory where Puppet state is stored. Generally, this directory can be removed without causing harm (although it might result in spurious service restarts).

• Default: $vardir/state

Where Puppet agent and Puppet Server store state associated with the running configuration. In the case of Puppet Server, this file reflects the state discovered through interacting with clients.

• Default: $statedir/state.yaml

How long the Puppet agent should cache when a resource was last checked or synced. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y). A value of 0 or unlimited will disable cache pruning.

This setting affects the usage of schedule resources, as the information about when a resource was last checked (and therefore when it needs to be checked again) is stored in the statefile. The statettl needs to be large enough to ensure that a resource will not trigger multiple times during a schedule due to its entry expiring from the cache.

• Default: 32d

Whether to compile a static catalog, which occurs only on Puppet Server when the code-id-command and code-content-command settings are configured in its puppetserver.conf file.

• Default: true

Whether to store each client's configuration, including catalogs, facts, and related data. This also enables the import and export of resources in the Puppet language - a mechanism for exchange resources between nodes.

By default this uses the 'puppetdb' backend.

You can adjust the backend using the storeconfigs_backend setting.

• Default: false

Configure the backend terminus used for StoreConfigs. By default, this uses the PuppetDB store, which must be installed and configured before turning on StoreConfigs.

• Default: puppetdb

The strictness level of puppet. Allowed values are:

• off - do not perform extra validation, do not report

• warning - perform extra validation, report as warning (default)

• error - perform extra validation, fail with error

The strictness level is for both language semantics and runtime evaluation validation. In addition to controlling the behavior with this primary server switch some individual warnings may also be controlled by the disable_warnings setting.

No new validations will be added to a micro (x.y.z) release, but may be added in minor releases (x.y.0). In major releases it expected that most (if not all) strictness validation become standard behavior.

• Default: warning

Whether the agent specified environment should be considered authoritative, causing the run to fail if the retrieved catalog does not match it.

• Default: false

Causes an evaluation error when referencing unknown variables. (This does not affect referencing variables that are explicitly set to undef).

• Default: false

Whether to print a transaction summary.

• Default: false

Checksum types supported by this agent for use in file resources of a static catalog. Values must be comma-separated. Valid types are sha256, sha256lite, sha384, sha512, sha224, sha1, sha1lite, md5, md5lite, mtime, ctime. Default is sha256, sha384, sha512, sha224, md5.

• Default: ["sha256", "sha384", "sha512", "sha224", "md5"]

What syslog facility to use when logging to syslog. Syslog has a fixed list of valid facilities, and you must choose one of those; you cannot just make one up.

• Default: daemon

Tags to use to find resources. If this is set, then only resources tagged with the specified tags will be applied. Values must be comma-separated.

Turns on experimental support for tasks and plans in the puppet language. This is for internal API use only. Do not change this setting.

• Default: false

The soft limit for the number of top level facts.

• Default: 512

Whether to print stack traces on some errors. Will print internal Ruby stack trace interleaved with Puppet function frames.

• Default: false

Transactional storage file for persisting data between transactions for the purposes of infering information (such as corrective_change) on new data received.

• Default: $statedir/transactionstore.yaml

The external trusted facts script or directory to use. This setting's value can be set to the path to an executable command that can produce external trusted facts or to a directory containing those executable commands. The command(s) must:

• Take the name of a node as a command-line argument.

• Return a JSON hash with the external trusted facts for this node.

• For unknown or invalid nodes, exit with a non-zero exit code.

If the setting points to an executable command, then the external trusted facts will be stored in the 'external' key of the trusted facts hash. Otherwise for each executable file in the directory, the external trusted facts will be stored in the <basename> key of the trusted['external'] hash. For example, if the files foo.rb and bar.sh are in the directory, then trusted['external'] will be the hash { 'foo' => <foo.rb output>, 'bar' => <bar.sh output> }.

• Default: ``

File that provides mapping between custom SSL oids and user-friendly names

• Default: $confdir/custom_trusted_oid_mapping.yaml

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. Because a Puppet agent using cached catalogs does not contact the primary server for a new catalog, it also does not upload facts at the beginning of the Puppet run.

• Default: false

Puppet saves both the initial and converged environment in the last_run_summary file. If they differ, and this setting is set to true, we will use the last converged environment and skip the node request.

When set to false, we will do the node request and ignore the environment data from the last_run_summary file.

• Default: true

Whether the server will search for SRV records in DNS for the current domain.

• Default: false

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

The user Puppet Server will run as. Used to ensure the agent side processes (agent, apply, etc) create files and directories readable by Puppet Server when necessary.

• Default: puppet

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

• Default: Unix/Linux: /opt/puppetlabs/puppet/cache -- Windows: C:\ProgramData\PuppetLabs\puppet\cache -- Non-root user: ~/.puppetlabs/opt/puppet/cache

The directory containing vendored modules. These modules will be used by all environments like those in the basemodulepath. The only difference is that modules in the basemodulepath are pluginsynced, while vendored modules are not

• Default: /opt/puppetlabs/puppet/vendor_modules

Whether or not to look for versioned environment directories, symlinked from $environmentpath/<environment>. This is an experimental feature and should be used with caution.

• Default: false

How frequently puppet agent should ask for a signed certificate.

When starting for the first time, puppet agent will submit a certificate signing request (CSR) to the server named in the ca_server setting (usually the primary Puppet server); this may be autosigned, or may need to be approved by a human, depending on the CA server's configuration.

Puppet agent cannot apply configurations until its approved certificate is available. Since the certificate may or may not be available immediately, puppet agent will repeatedly try to fetch it at this interval. You can turn off waiting for certificates by specifying a time of 0, or a maximum amount of time to wait in the maxwaitforcert setting, in which case puppet agent will exit if it cannot get a cert. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 2m

How frequently puppet agent should try running when there is an already ongoing puppet agent instance.

This argument is by default disabled (value set to 0). In this case puppet agent will immediately exit if it cannot run at that moment. When a value other than 0 is set, this can also be used in combination with the maxwaitforlock argument. This setting can be a time interval in seconds (30 or 30s), minutes (30m), hours (6h), days (2d), or years (5y).

• Default: 0

Whether to write the classfile and resourcefile after applying the catalog. It is enabled by default, except when running puppet apply.

• Default: true

The directory in which YAML data is stored, usually in a subdirectory.

• Default: $vardir/yaml
