puppetlabs-puppetdb

Purpose: Install and manage the PuppetDB server and database, and configure the Puppet master to use PuppetDB Module: puppetlabs/puppetdb (http://forge.puppetlabs.com/puppetlabs/puppetdb) Puppet Version: 2.7+ Platforms: RHEL6, Debian6, Ubuntu 10.04

Installing and configuring PuppetDB isn’t too difficult, but we knew that it could and should be even easier than it was. That’s where the new puppetlabs/puppetdb module comes in. Whether you just want to throw PuppetDB onto a test system as quickly as possible so that you can check it out, or you want finer-grained access to managing the individual settings and configuration, this module aims to let you dive in at exactly the level of involvement that you desire.

Here are some of the capabilities of the module; almost all of these are optional, so you are free to pick and choose which ones suit your needs:

• Installs and manages the core PuppetDB server
• Installs and manages the underlying database server (PostgreSQL or a simple embedded database)
• Configures your Puppet master to use PuppetDB
• Optional support for opening the PuppetDB port in your firewall on RedHat-based distros
• Validates your database connection before applying PuppetDB configuration changes, to help make sure that PuppetDB doesn’t end up in a broken state
• Validates your PuppetDB connection before applying configuration changes to the Puppet master, to help make sure that your master doesn’t end up in a broken state

Examples

In the tests directory, there are example manifests that show how you can do a basic setup in a few different configurations. They include examples of setting up PuppetDB and all of its dependencies all on the same node as your Puppet master, and also an example of a 3-node distributed setup in which Puppet, PuppetDB, and PostgreSQL are all running on separate machines.

Also, see README_GETTING_STARTED.md for a little more of a guided tour.

Resource Overview

puppetdb class

This is a sort of ‘all-in-one’ class for the PuppetDB server. It’ll get you up and running with everything you need (including database setup and management) on the server side. The only other thing you’ll need to do is to configure your Puppet master to use PuppetDB... which leads us to:

puppetdb::master::config class

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.

NOTE: Using this class involves allowing the module to manipulate your puppet configuration files; in particular: 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.

puppetdb::server class

This is for managing the PuppetDB server independently of the underlying database that it depends on; so it’ll manage the PuppetDB package, service, config files, etc., but will allow you to manage the database (e.g. postgresql) however you see fit.

puppetdb::database::postgresql class

This is a class for managing 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.

Low-level classes

There are several lower-level classes in the module (e.g., puppetdb::master::* and puppetdb::server::* which you can use to manage individual configuration files or other parts of the system. In the interest of brevity, we’ll skip over those for now... but if you need more fine-grained control over your setup, feel free to dive into the module and have a look!)
