    class { 'hosts': }

Install hosts with the recommended parameters.

    class { 'hosts':
      config_file_template => "hosts/${::lsbdistcodename}/etc/hosts.erb",
    }

Usage

Update the hosts package.

    class { 'hosts':
      package_ensure => 'latest',
    }

Remove the hosts package.

    class { 'hosts':
      package_ensure => 'absent',
    }

Purge the hosts package (All configuration files will be removed).

    class { 'hosts':
      package_ensure => 'purged',
    }

Deploy the configuration files from source directory.

    class { 'hosts':
      config_dir_source => "puppet:///modules/hosts/${::lsbdistcodename}/etc",
    }

Deploy the configuration files from source directory (Unmanaged configuration files will be removed).

    class { 'hosts':
      config_dir_purge  => true,
      config_dir_source => "puppet:///modules/hosts/${::lsbdistcodename}/etc",
    }

Deploy the configuration file from source.

    class { 'hosts':
      config_file_source => "puppet:///modules/hosts/${::lsbdistcodename}/etc/hosts",
    }

Deploy the configuration file from string.

    class { 'hosts':
      config_file_string => '# THIS FILE IS MANAGED BY PUPPET',
    }

Deploy the configuration file from template.

    class { 'hosts':
      config_file_template => "hosts/${::lsbdistcodename}/etc/hosts.erb",
    }

Deploy the configuration file from custom template (Additional parameters can be defined).

    class { 'hosts':
      config_file_template     => "hosts/${::lsbdistcodename}/etc/hosts.erb",
      config_file_options_hash => {
        'key' => 'value',
      },
    }

Deploy additional configuration files from source, string or template.

    class { 'hosts':
      config_file_hash => {
        'hosts.2nd' => {
          config_file_path   => '/etc/hosts.2nd',
          config_file_source => "puppet:///modules/hosts/${::lsbdistcodename}/etc/hosts.2nd",
        },
        'hosts.3rd' => {
          config_file_path   => '/etc/hosts.3rd',
          config_file_string => '# THIS FILE IS MANAGED BY PUPPET',
        },
        'hosts.4th' => {
          config_file_path     => '/etc/hosts.4th',
