By guiding puppetdb setup and configuration with a Puppet master, the PuppetDB module provides fast, streamlined access to data on puppetized infrastructure.
The PuppetDB module provides a quick way to get started using PuppetDB, an open source inventory resource service that manages storage and retrieval of platform-generated data. The module will install PostgreSQL and PuppetDB if you don't have them, as well as set up the connection to Puppet master. The module will also provide a dashboard you can use to view the current state of your system.
For more information about PuppetDB please see the official PuppetDB documentation.
What PuppetDB affects:
- package/service/configuration files for PuppetDB
- package/service/configuration files for PostgreSQL (optional, but set as default)
- Puppet master's runtime (via plugins)
- Puppet master's configuration
- note: Using the
puppetdb::master::config
class will cause your routes.yaml file to be overwritten entirely (see Usage below for options and more information )
- note: Using the
- system firewall (optional)
- listened-to ports
Introductory Questions
To begin using PuppetDB, you’ll have to make a few decisions:
- Which database back-end should I use?
- PostgreSQL (default) or our embedded database
- Embedded database
- note: As of PuppetDB 4.0, the embedded database is no longer supported as an option. When running PuppetDB 3.x, we suggest using the embedded database only for experimental environments rather than production, as it does not scale well and can cause difficulty in migrating to PostgreSQL.
- Should I run the database on the same node that I run PuppetDB on?
- Should I run PuppetDB on the same node that I run my master on?
The answers to those questions will be largely dependent on your answers to questions about your Puppet environment:
- How many nodes are you managing?
- What kind of hardware are you running on?
- Is your current load approaching the limits of your hardware?
Depending on your answers to all of the questions above, you will likely fall under one of these set-up options:
This approach assumes you will use our default database (PostgreSQL) and run everything (PostgreSQL, PuppetDB, Puppet master) all on the same node. This setup will be great for a testing or experimental environment. In this case, your manifest will look like:
node <hostname> {
# Configure puppetdb and its underlying database
class { 'puppetdb': }
# Configure the Puppet master to use puppetdb
class { 'puppetdb::master::config': }
}
You can provide some parameters for these classes if you’d like more control, but that is literally all that it will take to get you up and running with the default configuration.
This approach is for those who prefer not to install PuppetDB on the same node as the Puppet master. Your environment will be easier to scale if you are able to dedicate hardware to the individual system components. You may even choose to run the puppetdb server on a different node from the PostgreSQL database that it uses to store its data. So let’s have a look at what a manifest for that scenario might look like:
This is an example of a very basic 3-node setup for PuppetDB.
$puppetdb_host = 'puppetdb.example.lan'
$postgres_host = 'postgres.example.lan'
node 'master.example.lan' {
# Here we configure the Puppet master to use PuppetDB,
# telling it the hostname of the PuppetDB node
class { 'puppetdb::master::config':
puppetdb_server => $puppetdb_host,
}
}
node 'postgres.example.lan' {
# Here we install and configure PostgreSQL and the PuppetDB
# database instance, and tell PostgreSQL that it should
# listen for connections to the `$postgres_host`
class { 'puppetdb::database::postgresql':
listen_addresses => $postgres_host,
}
}
node 'puppetdb.example.lan' {
# Here we install and configure PuppetDB, and tell it where to
# find the PostgreSQL database.
class { 'puppetdb::server':
database_host => $postgres_host,
}
}
This should be all it takes to get a 3-node, distributed installation of PuppetDB up and running. Note that, if you prefer, you could easily move two of these classes to a single node and end up with a 2-node setup instead.
To use SSL connections for the single node setup, use the following manifest:
node <hostname> {
# Here we configure puppetdb and PostgreSQL to use ssl connections
class { 'puppetdb':
postgresql_ssl_on => true,
database_host => '<hostname>',
database_listen_address => '0.0.0.0'
}
# Configure the Puppet master to use puppetdb
class { 'puppetdb::master::config': }
To use SSL connections for the multiple nodes setup, use the following manifest:
$puppetdb_host = 'puppetdb.example.lan'
$postgres_host = 'postgres.example.lan'
node 'master.example.lan' {
# Here we configure the Puppet master to use PuppetDB,
# telling it the hostname of the PuppetDB node.
class { 'puppetdb::master::config':
puppetdb_server => $puppetdb_host,
}
}
node 'postgres.example.lan' {
# Here we install and configure PostgreSQL and the PuppetDB
# database instance, and tell PostgreSQL that it should
# listen for connections to the `$postgres_host`.
# We also enable SSL connections.
class { 'puppetdb::database::postgresql':
listen_addresses => $postgres_host,
postgresql_ssl_on => true,
puppetdb_server => $puppetdb_host
}
}
node 'puppetdb.example.lan' {
# Here we install and configure PuppetDB, and tell it where to
# find the PostgreSQL database. We also enable SSL connections.
class { 'puppetdb::server':
database_host => $postgres_host,
postgresql_ssl_on => true
}
}
Whether you choose a single node development setup or a multi-node setup, a basic setup of PuppetDB will cause: PostgreSQL to install on the node if it’s not already there; PuppetDB postgres database instance and user account to be created; the postgres connection to be validated and, if successful, PuppetDB to be installed and configured; PuppetDB connection to be validated and, if successful, the Puppet master config files to be modified to use PuppetDB; and the Puppet master to be restarted so that it will pick up the config changes.
If your logging level is set to INFO or finer, you should start seeing PuppetDB-related log messages appear in both your Puppet master log and your puppetdb log as subsequent agent runs occur.
It is worth noting that there are some cross-node dependencies, which means that the first time you add the module's configurations to your manifests, you may see a few failed puppet runs on the affected nodes.
PuppetDB handles cross-node dependencies by taking a sort of "eventual consistency" approach. There’s nothing that the module can do to control the order in which your nodes check in, but the module can check to verify that the services it depends on are up and running before it makes configuration changes--so that’s what it does.
When your Puppet master node checks in, it will validate the connectivity to the puppetdb server before it applies its changes to the Puppet master config files. If it can’t connect to puppetdb, then the puppet run will fail and the previous config files will be left intact. This prevents your master from getting into a broken state where all incoming puppet runs fail because the master is configured to use a puppetdb server that doesn’t exist yet. The same strategy is used to handle the dependency between the puppetdb server and the postgres server.
Hence the failed puppet runs. These failures should be limited to 1 failed run on the puppetdb node, and up to 2 failed runs on the Puppet master node. After that, all of the dependencies should be satisfied and your puppet runs should start to succeed again.
You can also manually trigger puppet runs on the nodes in the correct order (Postgres, PuppetDB, Puppet master), which will avoid any failed runs.
Significant parameter changes are listed below:
- The PuppetDB module defaults to Puppet 4 pathing and assumes
puppetserver
is the master service by default - The PuppetDB module manages Postgres repos by default. To turn this behavior
off, set
manage_package_repo
tofalse
. - To specify a specific version of PuppetDB to manage, you'll need to use the
puppetdb::globals
class to set the version of PuppetDB you're using explicitly. The ability to configure the version in thepuppetdb::server
andpuppetdb
class have been removed.
For example if your config looked like this before:
class {'puppetdb':
puppetdb_version => '3.2.4-1.el7',
}
class { 'puppetdb::master::config': }
and you'd still like to use the module with PuppetDB 3.2.4, all you'd have to change would be:
class { 'puppetdb::globals':
version => '3.2.4-1.el7',
}
class { 'puppetdb' : }
class { 'puppetdb::master::config' : }
The globals
class above takes into account the following PuppetDB 3 and Puppet
4 related changes:
* The puppetdb::master:puppetdb_conf
class has added a $legacy_terminus
to support the PuppetDB 2.x terminus configuration.
* The default test_url
for the PuppetDBConnValidator
has also been
changed to /pdb/meta/v1/version
but will default to /v3/version
when
using a PuppetDB 2.x version.
* The configuration pathing for Puppet and PuppetDB has changed with Puppet
4 and PuppetDB 3, using PuppetDB 2.x or older assumes the old
configuration pathing.
See the CHANGELOG file for more detailed information on changes for each release.
For this release, all dependency versions have been bumped to their latest. Significant parameter changes are listed below:
- The PuppetDB module now only supports Puppet 3.7.1 or later
puppetlabs/postgresql
4.0.0 or later is now requiredpuppetlabs/inifile
1.1.3 or later is now requiredpuppetlabs/firewall
1.1.3 or later is now requiredpuppetlabs/stdlib
4.2.2 or later is now required- The parameter
manage_firewall
for the classpuppetdb::database::postgresql
has now been removed, since the PostgreSQL module no longer supports this. - The parameter
open_postgres_port
for the classpuppetdb
has also been removed, due to PostgreSQL changes.
See the CHANGELOG file for more detailed information on changes for each release.
For this release a major dependency has changed. The module
pupppetlabs/postgresql
must now be version 3.x. Upgrading the module should
upgrade the puppetlabs/postgresql
module for you, but if another module has a
fixed dependency that module will have to be fixed before you can continue.
Some other changes include:
- The parameter
manage_redhat_firewall
for the classpuppetdb
has now been removed completely in favor ofopen_postgres_port
andopen_ssl_listen_port
. - The parameter
manage_redhat_firewall
for the classpuppetdb::database::postgresql
, has now been renamed tomanage_firewall
. - The parameter
manage_redhat_firewall
for the classpuppetdb::server
has now been removed completely in favor ofopen_listen_port
andopen_ssl_listen_port
. - The internal class:
puppetdb::database::postgresql_db
has been removed. If you were using this, it is now defunct. - The class
puppetdb::server::firewall
has been marked as private, do not use it directly. - The class
puppetdb::server::jetty_ini
andpuppetdb::server::database_ini
have been marked as private, do not use it directly.
A major dependency has been changed, so now when you upgrade to 2.0 the
dependency cprice404/inifile
has been replaced with puppetlabs/inifile
. This
may interfere with other modules as they may depend on the old
cprice404/inifile
instead, so upgrading should be done with caution. Check
that your other modules use the newer puppetlabs/inifile
module as
interoperation with the old cprice404/inifile
module will no longer be
supported by this module.
Depending on how you install your modules, changing the dependency may require
manual intervention. Double check your modules contain the newer
puppetlabs/inifile
after installing this latest module.
Otherwise, all existing parameters from 1.x should still work correctly.
PuppetDB supports a large number of configuration options for both configuring the puppetdb service and connecting that service to the Puppet master.
The puppetdb::globals
class is intended to provide similar functionality to
the postgresql::globals
class in the puppetlabs-postgresql
module by
exposing a top-level entry-point into the module so that we can properly set
defaults for the puppetdb::params
class based on the version of puppetdb
you
are using. This setting defaults to present
.
You must declare the class to use it:
class { 'puppetdb::globals': }
Parameters within puppetdb::globals
:
The version of the puppetdb
package that should be installed. You may specify
an explicit version number, 'present', or 'latest' (defaults to 'present').
The puppetdb
class is intended as a high-level abstraction (sort of an
'all-in-one' class) to help simplify the process of getting your puppetdb server
up and running. It wraps the slightly-lower-level classes puppetdb::server
and
puppetdb::database::*
, and it'll get you up and running with everything you
need (including database setup and management) on the server side. For maximum
configurability, you may choose not to use this class. You may prefer to use the
puppetdb::server
class directly, or manage your puppetdb setup on your own.
You must declare the class to use it:
class { 'puppetdb': }
Parameters within puppetdb
:
The address that the web server should bind to for HTTP requests. Defaults to
localhost
. Set to 0.0.0.0
to listen on all addresses.

(e.g. SSL_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
).
Defaults to undef
.
If true
, puppetdb will automatically migrate to the latest database format at startup. If false
, if the database format supplied by this version of PuppetDB doesn't match the version expected (whether newer or older), PuppetDB will exit with an error status. Defaults to true
.
If true, the PostgreSQL server will be managed by this module. Defaults to true
.
If true, the PostgreSQL database will be managed by this module. Defaults to true
.
Which database backend to use; legal values are postgres
(default)
or embedded
. The embedded
option is not supported on PuppetDB
4.0.0 or later. embedded
can be used for very small installations or
for testing, but is not recommended for use in production
environments. For more info, see the puppetdb
docs.
Hostname to use for the database connection. For single case installations this
should be left as the default. Defaults to localhost
, ignored for embedded
database.
The port that the database server listens on. Defaults to 5432
, ignored for
embedded
database.
The name of the database user to connect as. Defaults to puppetdb
, ignored for
embedded
database.
The password for the database user. Defaults to puppetdb
, ignored for
embedded
database.
Whether or not the database password in database.ini will be managed by this module.
Set this to false
if you want to set the password some other way.
Defaults to true
The name of the database instance to connect to. Defaults to puppetdb
, ignored
for embedded
database.
The text to append to the JDBC connection URI. This should begin with a '?'
character. For example, to use SSL for the PostgreSQL connection, set this
parameter's value to ?ssl=true
.
This setting is only available when using PostgreSQL; when using HyperSQL (the
embedded
database), it does nothing.
If true, the module will attempt to connect to the database using the specified
settings and fail if it is not able to do so. Defaults to true
.
Embedded Database Only Changes the path location for the HSQLDB database. Does not provide migration for old data, so if you change this value and you have an existing database you will need to manually move the content also. (defaults to package default for 2.x release).
The length of time a node can go without receiving any new data before it's automatically deactivated. (defaults to '7d', which is a 7-day period. Set to '0d' to disable auto-deactivation). This option is supported in PuppetDB >= 1.1.0.
The length of time a node can be deactivated before it's deleted from the database. (defaults to '14d', which is a 14-day period. Set to '0d' to disable purging). This option is supported in PuppetDB >= 1.2.0.
The length of time reports should be stored before being deleted. (defaults to
14d
, which is a 14-day period). This option is supported in PuppetDB >= 1.1.0.
This controls how often (in minutes) to compact the database. The compaction process reclaims space and deletes unnecessary rows. If not supplied, the default is every 60 minutes. This option is supported in PuppetDB >= 0.9.
This sets the number of seconds before an SQL query is considered "slow." Slow SQL queries are logged as warnings, to assist in debugging and tuning. Note PuppetDB does not interrupt slow queries; it simply reports them after they complete.
The default value is 10
seconds. A value of 0 will disable logging of slow
queries. This option is supported in PuppetDB >= 1.1.
The maximum time (in minutes) for a pooled connection to remain unused before it is closed off.
If not supplied, we default to 60
minutes. This option is supported in PuppetDB >= 1.1.
This sets the time (in minutes) for a connection to remain idle before sending a test query to the DB. This is useful to prevent a DB from timing out connections on its end.
If not supplied, we default to 45 minutes. This option is supported in PuppetDB >= 1.1.
The maximum time (in minutes) a pooled connection should remain open. Any connections older than this setting will be closed off. Connections currently in use will not be affected until they are returned to the pool.
If not supplied, we won't terminate connections based on their age alone. This option is supported in PuppetDB >= 1.4.
The PuppetDB package name in the package manager. Defaults to present
.
The name of the PuppetDB service. Defaults to puppetdb
.
Sets whether the service should be running
or stopped
. When set to stopped
the
service doesn't start on boot either. Valid values are true
, running
,
false
, and stopped
.
The PuppetDB configuration directory. Defaults to /etc/puppetdb/conf.d
.
The parent directory for the MQ's data directory.
Java VM options used for overriding default Java VM options specified in
PuppetDB package. Defaults to {}
. See
PuppetDB Configuration
to get more details about the current defaults.
For example, to set -Xmx512m -Xms256m
options use:
{
'-Xmx' => '512m',
'-Xms' => '256m',
}
Sets whether the provided java args should be merged with the defaults, or
should override the defaults. This setting is necessary if any of the defaults
are to be removed. Defaults to true. If false
, the java_args
in the PuppetDB
init config file will reflect only what is passed via the java_args
param.
Jetty option to explicitly set max-threads
. Defaults to undef
, so the
PuppetDB-Jetty default is used.
Which database backend to use for the read database. Only supports
postgres
(default). This option is supported in PuppetDB >= 1.6.
This parameter must be set to enable the PuppetDB read-database.
The hostname or IP address of the read database server. Defaults to undef
.
The default is to use the regular database for reads and writes. This option is
supported in PuppetDB >= 1.6.
The port that the read database server listens on. Defaults to 5432
. This
option is supported in PuppetDB >= 1.6.
The name of the read database user to connect as. Defaults to puppetdb
. This
option is supported in PuppetDB >= 1.6.
The password for the read database user. Defaults to puppetdb
. This option is
supported in PuppetDB >= 1.6.
Whether or not the database password in read-database.ini will be managed by this module.
Set this to false
if you want to set the password some other way.
Defaults to true
The name of the read database instance to connect to. Defaults to puppetdb
.
This option is supported in PuppetDB >= 1.6.
This sets the number of seconds before an SQL query to the read database is considered "slow." Slow SQL queries are logged as warnings, to assist in debugging and tuning. Note PuppetDB does not interrupt slow queries; it simply reports them after they complete.
The default value is 10 seconds. A value of 0 will disable logging of slow queries. This option is supported in PuppetDB >= 1.6.
The maximum time (in minutes) for a pooled read database connection to remain unused before it is closed off.
If not supplied, we default to 60 minutes. This option is supported in PuppetDB >= 1.6.
This sets the time (in minutes) for a read database connection to remain idle before sending a test query to the DB. This is useful to prevent a DB from timing out connections on its end.
If not supplied, we default to 45 minutes. This option is supported in PuppetDB >= 1.6.
The maximum time (in minutes) a pooled read database connection should remain open. Any connections older than this setting will be closed off. Connections currently in use will not be affected until they are returned to the pool.
If not supplied, we won't terminate connections based on their age alone. This option is supported in PuppetDB >= 1.6.
Base directory for PuppetDB SSL configuration. Defaults to /etc/puppetdb/ssl
or /etc/puppetlabs/puppetdb/ssl
for FOSS and PE respectively.
A switch to enable or disable the management of SSL certificates in your
jetty.ini
configuration file.
Path to your SSL certificate for populating jetty.ini
.
Path to your SSL key for populating jetty.ini
.
Path to your SSL CA for populating jetty.ini
.
A boolean switch to enable or disable the management of SSL keys in your
ssl_dir
. Default is false
.
Contents of your SSL key, as a string.
Contents of your SSL certificate, as a string.
Contents of your SSL CA certificate, as a string.
If true
, puppet will manage your iptables rules for PuppetDB via the
puppetlabs-firewall class.
The number of command processing threads to use. Defaults to undef
, using the
PuppetDB built-in default.
The number of threads allowed to write to disk at any one time. Defaults to
undef
, which uses the PuppetDB built-in default.
The amount of disk space (in MB) to allow for persistent message storage.
Defaults to undef
, using the PuppetDB built-in default.
The amount of disk space (in MB) to allow for temporary message storage.
Defaults to undef
, using the PuppetDB built-in default.
Setting this to true disables checking for updated versions of PuppetDB and sending basic analytics data to Puppet.
Defaults to undef
, using the PuppetDB built-in default.
The name of the certificate whitelist file to set up and configure in PuppetDB. Defaults to /etc/puppetdb/certificate-whitelist
or /etc/puppetlabs/puppetdb/certificate-whitelist
for FOSS and PE respectively.
Array of the X.509 certificate Common Names of clients allowed to connect to PuppetDB. Defaults to empty. Be aware that this permits full access to all Puppet clients to download anything contained in PuppetDB, including the full catalogs of all nodes, which possibly contain sensitive information. Set to [ $::servername ]
to allow access only from your (single) Puppet master, which is enough for normal operation. Set to a list of Puppet masters if you have multiple.
PuppetDB creates Dead Letter Office. Those are reports of failed requests. They spill up the disk. This parameter is a boolean and defaults to false. You can enable automatic cleanup of DLO reports by setting this to true.
The DLO cleanup is a systemd timer if systemd is available, otherwise a
cronjob. The variable configures the systemd.timer option onCalender.
It defaults to *-*-* ${fqdn_rand(24)}:${fqdn_rand(60)}:00
. This will start
the cleanup service on a daily basis. The exact minute and hour is random
per node based on the fqdn_rand
method. On non-systemd systems, the cron runs daily and the $puppetdb_user
needs
to be able to run cron jobs. On systemd systems you need the camptocamp/systemd
module, which is an optional dependency and not automatically installed!
This is a positive integer. It describes the amount of days you want to keep the DLO reports. The default value is 90 days.
The puppetdb::server
class manages the PuppetDB server independently of the
underlying database that it depends on. It will manage the PuppetDB package,
service, config files, etc., but will still allow you to manage the database
(e.g. PostgreSQL) however you see fit.
class { 'puppetdb::server':
database_host => 'pg1.mydomain.com',
}
The puppetdb::master::config
class directs your Puppet master to use PuppetDB,
which means that this class should be used on your Puppet master node. It’ll
verify that it can successfully communicate with your PuppetDB server, and then
configure your master to use PuppetDB.
Using this class allows the module to manipulate the puppet configuration files
puppet.conf and routes.yaml. The puppet.conf changes are supplemental and should
not affect any of your existing settings, but the routes.yaml file will be
overwritten entirely. If you have an existing routes.yaml file, you will want to
take care to use the manage_routes
parameter of this class to prevent the module
from managing that file, and you’ll need to manage it yourself.
class { 'puppetdb::master::config':
puppetdb_server => 'my.host.name',
puppetdb_port => 8081,
}
Parameters within puppetdb::master::config
:
The dns name or ip of the PuppetDB server. Defaults to the hostname of the
current node, i.e. $::fqdn
.
The port that the PuppetDB server is running on. Defaults to 8081
.
If true, use plain HTTP to talk to PuppetDB. Defaults to the value of
disable_ssl
if PuppetDB is on the same server as the Puppet Master, or else
false. If you set this, you probably need to set puppetdb_port
to match the HTTP
port of the PuppetDB.
Boolean to fail in a soft manner if PuppetDB is not accessible for command
submission Defaults to false
.
If true
, the module will overwrite the Puppet master's routes file to
configure it to use PuppetDB. Defaults to true
.
If true
, the module will manage the Puppet master's storeconfig settings.
Defaults to true
.
If true
, the module will manage the 'reports' field in the puppet.conf file to
enable or disable the PuppetDB report processor. Defaults to false
.
If true
, the module will store values from puppetdb_server
and puppetdb_port
parameters in the PuppetDB configuration file. If false
, an existing PuppetDB
configuration file will be used to retrieve server and port values.
If true
, AND if restart_puppet
is true, then the module will create a service
resource for puppet_service_name
if it has not been defined. Defaults to true
.
If you are already declaring the puppet_service_name
service resource in another
part of your code, setting this to false
will avoid creation of that service
resource by this module, avoiding potential duplicate resource errors.
If true
, the module will fail if PuppetDB is not reachable, otherwise it will
preconfigure PuppetDB without checking.
Ignored unless manage_report_processor
is true
, in which case this setting
will determine whether or not the PuppetDB report processor is enabled (true
)
or disabled (false
) in the puppet.conf file.
Ignored unless manage_storeconfigs
is true
, in which case this setting
will determine whether or not client configuration storage is enabled (true
)
or disabled (false
) in the puppet.conf file.
Puppet's config directory. Defaults to /etc/puppet
.
Puppet's config file. Defaults to /etc/puppet/puppet.conf
.
A boolean switch to enable or disable the masterless setup of PuppetDB. Defaults
to false
.
Name of the package to use that represents the PuppetDB terminus code. Defaults
to puppetdb-termini
, when puppetdb_version
is set to <= 2.3.x
the default
changes to puppetdb-terminus
.
Name of the service that represents Puppet. You can change this to apache2
or
httpd
depending on your operating system, if you plan on having Puppet run
using Apache/Passenger for example.
The maximum amount of time that the module should wait for PuppetDB to start up. This is most important during the initial install of PuppetDB (defaults to 15 seconds).
If true
, the module will restart the Puppet master when PuppetDB configuration
files are changed by the module. Defaults to true
. If set to false
, you
must restart the service manually in order to pick up changes to the config
files (other than puppet.conf
).
The puppetdb::database::postgresql
class manages a PostgreSQL server for use
by PuppetDB. It can manage the PostgreSQL packages and service, as well as
creating and managing the PuppetDB database and database user accounts.
class { 'puppetdb::database::postgresql':
listen_addresses => 'my.postgres.host.name',
}
The listen_address
is a comma-separated list of hostnames or IP addresses on
which the postgres server should listen for incoming connections. This defaults
to localhost
. This parameter maps directly to PostgreSQL's listen_addresses
config option. Use a *
to allow connections on any accessible address.
Sets the name of the database. Defaults to puppetdb
.
Creates a user for access the database. Defaults to puppetdb
.
Sets the password for the database user above. Defaults to puppetdb
.
Conditionally manages the PostgreSQL server via postgresql::server
. Defaults
to true
. If set to false
, this class will create the database and user via
postgresql::server::db
but not attempt to install or manage the server itself.
The URL to use for testing if the PuppetDB instance is running. Defaults to
/pdb/meta/v1/version
.
If true
, the official postgresql.org repo will be added and postgres won't
be installed from the regular repository. Defaults to true
.
If the postgresql.org repo is installed, you can install several versions of
postgres. Defaults to 9.6
in module version 6.0+ and 9.4
in older versions.
In addition to the classes and variables mentioned above, PuppetDB includes:
puppetdb::master::routes
Configures the Puppet master to use PuppetDB as the facts terminus. WARNING: the current implementation simply overwrites your routes.yaml file; if you have an existing routes.yaml file that you are using for other purposes, you should not use this.
class { 'puppetdb::master::routes':
puppet_confdir => '/etc/puppet'
}
The optional parameter routes can be used to specify a custom route configuration. For example to configure routes for masterless puppet.
class { 'puppetdb::master::routes':
routes => {
'apply' => {
'facts' => {
'terminus' => 'facter',
'cache' => 'puppetdb_apply',
}
}
}
}
puppetdb::master::storeconfigs
Configures the Puppet master to enable storeconfigs and to use PuppetDB as the storeconfigs backend.
class { 'puppetdb::master::storeconfigs':
puppet_conf => '/etc/puppet/puppet.conf'
}
puppetdb::server::validate_db
Validates that a successful database connection can be established between the node on which this resource is run and the specified PuppetDB database instance (host/port/user/password/database name).
puppetdb::server::validate_db { 'validate my puppetdb database connection':
database_host => 'my.postgres.host',
database_username => 'mydbuser',
database_password => 'mydbpassword',
database_name => 'mydbname',
}
puppetdb_conn_validator
Verifies that a connection can be successfully established between a node and the PuppetDB server. Its primary use is as a precondition to prevent configuration changes from being applied if the PuppetDB server cannot be reached, but it could potentially be used for other purposes such as monitoring.
Currently, PuppetDB is compatible with:

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.
We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
