# Class: puppetdb::server
#
# This class provides a simple way to get a puppetdb instance up and running
# with minimal effort.  It will install and configure all necessary packages for
# the puppetdb server, but will *not* manage the database (e.g., postgres) server
# or instance (unless you are using the embedded database, in which case there
# is not much to manage).
#
# This class is intended as a high-level abstraction to help simplify the process
# of getting your puppetdb server up and running; it manages the puppetdb
# package and service, as well as several puppetdb configuration files.  For
# maximum configurability, you may choose not to use this class.  You may prefer to
# manage the puppetdb package / service on your own, and perhaps use the
# individual classes inside of the `puppetdb::server` namespace to manage some
# or all of your configuration files.
#
# In addition to this class, you'll need to configure your puppetdb postgres
# database if you are using postgres.  You can optionally do by using the
# `puppetdb::database::postgresql` class.
#
# You'll also need to configure your puppet master to use puppetdb.  You can
# use the `puppetdb::master::config` class to accomplish this.
#
# Parameters:
#   ['ssl_listen_address'] - The address that the web server should bind to
#                            for HTTPS requests.  (defaults to `$::clientcert`.)
#   ['ssl_listen_port']    - The port on which the puppetdb web server should
#                            accept HTTPS requests.
#   ['database']           - Which database backend to use; legal values are
#                            `postgres` (default) or `embedded`.  (The `embedded`
#                            db 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']      - The hostname or IP address of the database server.
#                            (defaults to `localhost`; ignored for `embedded` db)
#   ['database_port']      - The port that the database server listens on.
#                            (defaults to `5432`; ignored for `embedded` db)
#   ['database_user']      - The name of the database user to connect as.
#                            (defaults to `puppetdb`; ignored for `embedded` db)
#   ['database_password']  - The password for the database user.
#                            (defaults to `puppetdb`; ignored for `embedded` db)
#   ['database_name']      - The name of the database instance to connect to.
#                            (defaults to `puppetdb`; ignored for `embedded` db)
#   ['manage_redhat_firewall'] - boolean indicating whether or not the module
#                            should open a port in the firewall on redhat-based
#                            systems.  Defaults to `true`.  This parameter is
#                            likely to change in future versions.  Possible
#                            changes include support for non-RedHat systems and
#                            finer-grained control over the firewall rule
#                            (currently, it simply opens up the postgres port to
#                            all TCP connections).
#   ['confdir']            - The puppetdb configuration directory; defaults to
#                            `/etc/puppetdb/conf.d`.
#
# Actions:
# - Creates and manages a puppetdb server
#
# Requires:
# - `inkling/postgresql`
#
# Sample Usage:
#     class { 'puppetdb::server':
#         database_host     => 'puppetdb-postgres',
#     }
