Puppet module for managing Foreman

Installs and configures Foreman, part of the Foreman installer or to be used as a Puppet module.

Many Foreman plugins can be installed by adding additional foreman::plugin::* classes, extra compute resource support via foreman::compute::* classes and the Hammer CLI can be installed by adding foreman::cli.

By default, it configures Foreman to run as a standalone service fronted by Apache as a reverse proxy with a PostgreSQL database.

The web interface is configured to use Puppet's SSL certificates by default, so ensure they're present first, reconfigure server_ssl_* or disable the ssl parameter. When used with the 'puppet' module, it will generate a new CA and the required certificate.

Lots of parameters are supplied to tune the default installation, which may be found in the class documentation at the top of each manifest.

Other modules may be used in combination with this one: puppet for managing a Puppet master and agent, and foreman_proxy to configure Foreman's Smart Proxy and related services.

Database support

The default database is PostgreSQL, which will be fully installed and managed on the host this module is applied to. Databases will be created with using the en_US.utf8 locale, which means a respective OS locale must be available on the database host. The database management can be disabled with db_manage.

Rails Cache support

Foreman supports different backends as Rails cache. This is handled by this module using the parameter rails_cache_store. The parameter takes a hash containing the type and options specfic to the backend.

The default is the file backend, configured via {'type' => 'file'}. To setup for redis use a hash similar to {'type' => 'redis', 'urls' => ['localhost:8479/4'], 'options' => {'compress' => 'true', 'namespace' => 'foreman'}} where urls takes an array of redis urls which get prepended with redis:// and options using a hash with options from rails falling back to {'compress' => 'true', 'namespace' => 'foreman'} if no option is provided.

An example configuration for activating the redis backend with a local instance could look like this:

class { 'foreman':
  rails_cache_store => {
    'type' => 'redis',
    'urls' => ['localhost:8479/4'],
    'options' => {
      'compress' => 'true',
      'namespace' => 'foreman'
    }
  }
}

Support policy

At any time, the module supports two releases, however the previous version may require parameters to be changed from their default values. These should be noted below.

Thus 'master' will support the upcoming major version and the current stable. The latest release (git tag, Puppet Forge) should support current and the previous stable release.

Foreman version compatibility notes

This module targets Foreman 3.1+. The module can not be used to manage Foreman installations on EL7.

This module configures Apache to serve static assets from /var/lib/foreman/public directly. This requires an appropriate SELinux policy, like the one introduced in foreman-selinux version 3.5. Additionally, some plugin packages might be incomplatible with such a deployment. To serve assets via Rails again, set foreman::config::apache::proxy_assets to true.

Types and providers

foreman_config_entry can be used to manage settings in Foreman's database, as seen in Administer > Settings. The cli provider uses foreman-rake to change settings.

foreman_smartproxy can create and manage registered smart proxies in Foreman's database. The rest_v3 provider uses the API with Ruby's HTTP library, OAuth and JSON.

foreman_hostgroup can be used to create and destroy hostgroups. Nested hostgroups are supported and hostgroups can be assigned to locations/organizations. The type currently doesn't support other properties such as environment, puppet classes etc.

Foreman ENC via hiera

There is a function foreman::enc to retrieve the ENC data. This returns the data as a hash and can be used in Hiera. This requires the URL to use the Puppet CA infrastructure:

---
version: 5
hierarchy:
  - name: "Foreman ENC"
    data_hash: foreman::enc
    options:
      url: https://foreman.example.com

It is also possible to use HTTP basic auth by adding a username/password to the URL in the form of https://username:password@foreman.example.com.

Then within your manifests you can use lookup. For example, in manifests/site.pp:

node default {
  lookup('classes', {merge => unique}).include
}
