# Class: profiles::yum::epel
#
# This class manages the EPEL yum repository for the system.
#
# Parameters:
# -----------
# - $baseurl: The base URL for the EPEL yum repository. This should be the root
#             URL of your EPEL mirror server.
#
# Actions:
# --------
# - Checks the OS release version.
#
# - If the release version is 7, 8, or 9, it sets up the 'epel' yum repository 
#   and installs the EPEL release RPM from the provided baseurl.
#
# - If the release version is not supported, it raises an error.
#
# - The repo configuration includes the baseurl parameterized with the OS
#   release version and architecture, and specifies the GPG key.
#
# Example usage:
# --------------
# To use this class with the default parameters:
#   include profiles::yum::epel
#
# To specify a custom base URL:
#   class { 'profiles::yum::epel':
#     baseurl => 'http://mylocalmirror.com/yum',
#   }
class profiles::yum::epel (
  Array[String] $managed_repos,

  $basearch = $facts['os']['architecture']

  if 'epel' in $managed_repos {
    if ($releasever in [7,8,9]) {
      $source = "${baseurl}/epel-release-latest-${releasever}.noarch.rpm"

      yum::install { 'epel-release':
        ensure => present,
        source => $source,
      }
    } else {
      err("Unsupported OS release ${releasever}")
    }
