Overview

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.

Setup

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:

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:

Single Node (Testing and Development)
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.

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

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.

Usage

PuppetDB supports a large number of configuration options for both configuring the puppetdb service and connecting that service to the Puppet master.

puppetdb::globals

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:

`version`

The version of the puppetdb package that should be installed. You may specify an explicit version number, 'present', or 'latest' (defaults to 'present').

puppetdb

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:

`listen_address`

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.

`listen_port`

The port on which the puppetdb web server should accept HTTP requests. Defaults to 8080.

`disable_cleartext`

If true, the puppetdb web server will only serve HTTPS and not HTTP requests (defaults to false).

`open_listen_port`

If true, open the http_listen_port on the firewall. Defaults to false.

`ssl_listen_address`

The address that the web server should bind to for HTTPS requests. Defaults to 0.0.0.0 to listen on all addresses.

`ssl_listen_port`

The port on which the puppetdb web server should accept HTTPS requests. Defaults to 8081.

`disable_ssl`

If true, the puppetdb web server will only serve HTTP and not HTTPS requests. Defaults to false.

`open_ssl_listen_port`

If true, open the ssl_listen_port on the firewall. Defaults to undef.

`ssl_protocols`

Specify the supported SSL protocols for PuppetDB (e.g. TLSv1, TLSv1.1, TLSv1.2.)

`cipher_suites`

Configure jetty's supported cipher-suites (e.g. SSL_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384). Defaults to undef.

`migrate`

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.

`manage_dbserver`

If true, the PostgreSQL server will be managed by this module. Defaults to true.

`manage_database`

If true, the PostgreSQL database will be managed by this module. Defaults to true.

`database`

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.

`database_host`

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.

`database_port`

The port that the database server listens on. Defaults to 5432, ignored for embedded database.

`database_username`

The name of the database user to connect as. Defaults to puppetdb, ignored for embedded database.

`database_password`

The password for the database user. Defaults to puppetdb, ignored for embedded database.

`manage_db_password`

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

`database_name`

The name of the database instance to connect to. Defaults to puppetdb, ignored for embedded database.

`jdbc_ssl_properties`

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.

`database_validate`

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.

`database_embedded_path`

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).

`node_ttl`

The length of time a node can go without receiving any new data before it's automatically deactivated. (defaults to '0', which disables auto-deactivation). This option is supported in PuppetDB >= 1.1.0.

`node_purge_ttl`

The length of time a node can be deactivated before it's deleted from the database. (defaults to '0', which disables purging). This option is supported in PuppetDB >= 1.2.0.

`report_ttl`

The length of time reports should be stored before being deleted. (defaults to 7d, which is a 7-day period). This option is supported in PuppetDB >= 1.1.0.

`gc_interval`

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.

`log_slow_statements`

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.

`conn_max_age`

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.

`conn_keep_alive`

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.

`conn_lifetime`

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.

`puppetdb_package`

The PuppetDB package name in the package manager. Defaults to present.

`puppetdb_service`

The name of the PuppetDB service. Defaults to puppetdb.

`puppetdb_service_status`

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.

`confdir`

The PuppetDB configuration directory. Defaults to /etc/puppetdb/conf.d.

`vardir`

The parent directory for the MQ's data directory.

`java_args`

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',
}

`merge_default_java_args`

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.

`max_threads`

Jetty option to explicitly set max-threads. Defaults to undef, so the PuppetDB-Jetty default is used.

`read_database`

Which database backend to use for the read database. Only supports postgres (default). This option is supported in PuppetDB >= 1.6.

`read_database_host`

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.

`read_database_port`

The port that the read database server listens on. Defaults to 5432. This option is supported in PuppetDB >= 1.6.

`read_database_username`

The name of the read database user to connect as. Defaults to puppetdb. This option is supported in PuppetDB >= 1.6.

`read_database_password`

The password for the read database user. Defaults to puppetdb. This option is supported in PuppetDB >= 1.6.

`manage_read_db_password`

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

`read_database_name`

The name of the read database instance to connect to. Defaults to puppetdb. This option is supported in PuppetDB >= 1.6.

`read_log_slow_statements`

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.

`read_conn_max_age`

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.

`read_conn_keep_alive`

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.

`read_conn_lifetime`

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.

`ssl_dir`

Base directory for PuppetDB SSL configuration. Defaults to /etc/puppetdb/ssl or /etc/puppetlabs/puppetdb/ssl for FOSS and PE respectively.

`ssl_set_cert_paths`

A switch to enable or disable the management of SSL certificates in your jetty.ini configuration file.

`ssl_cert_path`

Path to your SSL certificate for populating jetty.ini.

`ssl_key_path`

Path to your SSL key for populating jetty.ini.

`ssl_ca_cert_path`

Path to your SSL CA for populating jetty.ini.

`ssl_deploy_certs`

A boolean switch to enable or disable the management of SSL keys in your ssl_dir. Default is false.

`ssl_key`

Contents of your SSL key, as a string.

`ssl_cert`

Contents of your SSL certificate, as a string.

`ssl_ca_cert`

Contents of your SSL CA certificate, as a string.

`manage_firewall`

If true, puppet will manage your iptables rules for PuppetDB via the puppetlabs-firewall class.

`command_threads`

The number of command processing threads to use. Defaults to undef, using the PuppetDB built-in default.

`concurrent_writes`

The number of threads allowed to write to disk at any one time. Defaults to undef, which uses the PuppetDB built-in default.

`store_usage`

The amount of disk space (in MB) to allow for persistent message storage. Defaults to undef, using the PuppetDB built-in default.

`temp_usage`

The amount of disk space (in MB) to allow for temporary message storage. Defaults to undef, using the PuppetDB built-in default.

`disable_update_checking`

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.

`certificate_whitelist_file`

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.

`certificate_whitelist`

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.

`automatic_dlo_cleanup`

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.

`cleanup_timer_interval`

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!

`dlo_max_age`

This is a positive integer. It describes the amount of days you want to keep the DLO reports. The default value is 90 days.

puppetdb::server

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',
}

puppetdb::master::config

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:

`puppetdb_server`

The dns name or ip of the PuppetDB server. Defaults to the hostname of the current node, i.e. $::fqdn.

`puppetdb_port`

The port that the PuppetDB server is running on. Defaults to 8081.

`puppetdb_disable_ssl`

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.

`puppetdb_soft_write_failure`

Boolean to fail in a soft manner if PuppetDB is not accessible for command submission Defaults to false.

`manage_routes`

If true, the module will overwrite the Puppet master's routes file to configure it to use PuppetDB. Defaults to true.

`manage_storeconfigs`

If true, the module will manage the Puppet master's storeconfig settings. Defaults to true.

`manage_report_processor`

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.

`manage_config`

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.

`create_puppet_service_resource`

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.

`strict_validation`

If true, the module will fail if PuppetDB is not reachable, otherwise it will preconfigure PuppetDB without checking.

`enable_reports`

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.

`enable_storeconfigs`

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_confdir`

Puppet's config directory. Defaults to /etc/puppet.

`puppet_conf`

Puppet's config file. Defaults to /etc/puppet/puppet.conf.

`masterless`

A boolean switch to enable or disable the masterless setup of PuppetDB. Defaults to false.

`terminus_package`

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.

`puppet_service_name`

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.

`puppetdb_startup_timeout`

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).

`restart_puppet`

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).

puppetdb::database::postgresql

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',
}

`listen_addresses`

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.

`database_name`

Sets the name of the database. Defaults to puppetdb.

`database_username`

Creates a user for access the database. Defaults to puppetdb.

`database_password`

Sets the password for the database user above. Defaults to puppetdb.

`manage_server`

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.

`test_url`

The URL to use for testing if the PuppetDB instance is running. Defaults to /pdb/meta/v1/version.

`manage_package_repo`

If true, the official postgresql.org repo will be added and postgres won't be installed from the regular repository. Defaults to true.

`postgres_version`

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.

Implementation

Resource overview

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':

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',
}

Custom Types

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.

Limitations

Currently, PuppetDB is compatible with:

Puppet Version: 4.10+

Platforms:

EL 5, 6, 7
Debian 6, 7
Ubuntu 10.04, 12.04, 14.04

Community Maintained Platforms:

Archlinux
OpenBSD 5.6-current and newer
SLES 11 SP1

Development

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.

You can read the complete contribution guide.
