By guiding puppetdb setup and configuration with a Puppet master, the PuppetDB module provides fast, streamlined access to data on puppetized infrastructure.

Module Description

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 )
  • system firewall (optional)
  • listened-to ports

Introductory Questions

To begin using PuppetDB, you’ll have to make a few decisions:

  • 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:

  1. Single Node (Testing and Development)
  2. Multiple Node (Recommended)

Single Node Setup

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.

Multiple Node Setup

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.

Enable SSL connections

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 => ''
  # 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

Beginning with PuppetDB

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.

Cross-node Dependencies

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.


Upgrading from 4.x to 5.x

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 to false.
  • 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 the puppetdb::server and puppetdb 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.

Upgrading from 3.x to 4.x

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 required
  • puppetlabs/inifile 1.1.3 or later is now required
  • puppetlabs/firewall 1.1.3 or later is now required
  • puppetlabs/stdlib 4.2.2 or later is now required
  • The parameter manage_firewall for the class puppetdb::database::postgresql has now been removed, since the PostgreSQL module no longer supports this.
  • The parameter open_postgres_port for the class puppetdb has also been removed, due to PostgreSQL changes.

See the CHANGELOG file for more detailed information on changes for each release.

Upgrading from 2.x to 3.x

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 class puppetdb has now been removed completely in favor of open_postgres_port and open_ssl_listen_port.
  • The parameter manage_redhat_firewall for the class puppetdb::database::postgresql, has now been renamed to manage_firewall.
  • The parameter manage_redhat_firewall for the class puppetdb::server has now been removed completely in favor of open_listen_port and open_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 and puppetdb::server::database_ini have been marked as private, do not use it directly.

Upgrading from 1.x to 2.x

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': }


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': }


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 => '',


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 => '',
  puppetdb_port   => 8081,


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 => '',


Resource overview

In addition to the classes and variables mentioned above, PuppetDB includes:


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',


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'


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     => '',
  database_username => 'mydbuser',
  database_password => 'mydbpassword',
  database_name     => 'mydbname',

Custom Types


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:
