Puppet module for installing the Puppet agent and master

Installs and configures the Puppet agent and optionally a Puppet master (when server is true). Part of the Foreman installer or to be used as a Puppet module.

The Puppet master is configured under Apache and Passenger by default, unless server_passenger is set to false. When using Puppet Labs AIO packages (puppet-agent) the JVM-based Puppet Server is installed by default. For Puppet 3.x based installation, server_implementation can be set to puppetserver to switch to the JVM-based Puppet Server.

When using Puppet Server 2 (version 2.0 was the first version to support Puppet 4), the module supports and assumes you will be installing the latest version. If you know you'll be installing an earlier or specific version, you will need to override server_puppetserver_version. More information in the Puppet Server section below.

Many puppet.conf options for agents, masters and other are parameterized, with class documentation provided at the top of the manifests. In addition, there are hash parameters for each configuration section that can be used to supply any options that are not explicitly supported.

Environments support

The module helps configure Puppet environments using directory environments on Puppet 3.6+ and config environments on older versions. These are set up under /etc/puppet/environments/ - change server_environments to define the list to create, or use puppet::server::env for more control. When using directory environments with R10K you need to set the server_environments parameter to an empty array ie. [] to prevent r10k deploy environments from reporting an error caused by the creation of top level environment directory(s).

Git repo support

Environments can be backed by git by setting server_git_repo to true, which sets up /var/lib/puppet/puppet.git where each branch maps to one environment. Avoid using 'master' as this name isn't permitted. On each push to the repo, a hook updates /etc/puppet/environments with the contents of the branch.

Requires theforeman/git.

Foreman integration

With the 3.0.0 release the Foreman integration became optional. It will still by default install the Foreman integration when server is true, so if you wish to run a Puppet master without Foreman, it can be disabled by setting server_foreman to false.

Requires theforeman/foreman.

PuppetDB integration

The Puppet master can be configured to export catalogs and reports to a PuppetDB instance, using the puppetlabs/puppetdb module. Use its puppetdb::server class to install the PuppetDB server and this module to configure the Puppet master to connect to PuppetDB.

Requires puppetlabs/puppetdb <5.0.0.

Installation

Available from GitHub (via cloning or tarball), Puppet Forge or as part of the Foreman installer.

Usage

As a parameterized class, all the configurable options can be overridden from your wrapper classes or even your ENC (if it supports param classes). For example:

# Agent and cron (or daemon):
class { '::puppet': runmode => 'cron' }

# Agent and puppetmaster:
class { '::puppet': server => true }

# You want to use git?
class { '::puppet':
  server          => true
  server_git_repo => true
}

# You need need your own template for puppet.conf?
class { '::puppet':
  agent_template  => 'puppetagent/puppet.conf.core.erb',
  server          => true,
  server_template => 'puppetserver/puppet.conf.master.erb',
}

# Maybe you're using gitolite, new hooks, and a different port?
class { '::puppet':
  server                   => true
  server_port              => 8141,
  server_git_repo          => true,
  server_git_repo_path     => '/var/lib/gitolite/repositories/puppet.git',
  server_post_hook_name    => 'post-receive.puppet',
  server_post_hook_content => 'puppetserver/post-hook.puppet',
}

# Configure master without Foreman integration
class { '::puppet':
  server                => true,
  server_foreman        => false,
  server_reports        => 'store',
  server_external_nodes => '',
}

# The same example as above but overriding `server_environments` for R10K
class { '::puppet':
  server                => true,
  server_foreman        => false,
  server_reports        => 'store',
  server_external_nodes => '',
  server_environments   => [],
}

# Want to integrate with an existing PuppetDB?
class { '::puppet':
  server                      => true,
  server_puppetdb_host        => 'mypuppetdb.example.com',
  server_reports              => 'puppetdb,foreman',
  server_storeconfigs_backend => 'puppetdb',
}

Look in init.pp for what can be configured this way, see Contributing if anything doesn't work.

To use this in standalone mode, edit a file (e.g. install.pp), put in a class resource, as per the examples above, and the execute puppet apply e.g:

cat > install.pp <<EOF
class { '::puppet': server => true }
EOF
puppet apply install.pp --modulepath /path_to/extracted_tarball

Advanced scenarios

An HTTP (non-SSL) puppetmaster instance can be set up (standalone or in addition to the SSL instance) by setting the server_http parameter to true. This is useful for reverse proxy or load balancer scenarios where the proxy/load balancer takes care of SSL termination. The HTTP puppetmaster instance expects the X-Client-Verify, X-SSL-Client-DN and X-SSL-Subject HTTP headers to have been set on the front end server.

The listening port can be configured by setting server_http_port (which defaults to 8139).

By default, this HTTP instance accepts no connection (deny all in the <Directory> snippet). Allowed hosts can be configured by setting the server_http_allow parameter (which expects an array).

** Note that running an HTTP puppetmaster is a huge security risk when improperly configured. Allowed hosts should be tightly controlled; anyone with access to an allowed host can access all client catalogues and client certificates. **

# Configure an HTTP puppetmaster vhost in addition to the standard SSL vhost
class { '::puppet':
  server               => true,
  server_http          => true,
  server_http_port     => 8130, # default: 8139
  server_http_allow    => ['10.20.30.1', 'puppetbalancer.my.corp'],
}

Puppet Server configuration

Puppet Server requires slightly different configuration between different versions, which this module supports. It's recommended that you set the server_puppetserver_version parameter to the MAJOR.MINOR.PATCH version you have installed. By default the module will configure for the latest version available.

Currently supported values and configuration behaviours are:

• 2.5.x - configures the certificate authority in ca.cfg
• 2.4.99 (default) - configures for both 2.4 and 2.5, with bootstrap.cfg and ca.cfg
• 2.3.x, 2.4.x - configures the certificate authority and versioned-code-service in bootstrap.cfg
• 2.2.x or lower - configures the certificate authority in bootstrap.cfg
