Overview

The yum_cron module manages either the yum-cron or dnf-automatic (RHEL/CentOS 8+) package to allow for automatic updates and available updates notifications.

Backwards Compatibility

Version 3.x of this module modified the way apply_updates and download_updates parameters are handled. apply_updates now takes precedence over download_updates. If apply_updates is true then download_updates has no effect.

Version 2.x of this module added and removed many parameters. See CHANGELOG for detailed list of all the changes.

Version 1.x of this module replaced the disable_yum_autoupdate and remove_yum_autoupdate parameters with yum_autoupdate_ensure. The default behavior is still to disable yum-autoupdate.

Usage

Class: yum_cron

The default parameters will install and enable yum-cron to only check for updates and notify root if any are available. Generally, dnf-automatic uses different paths, but functions very similarly and has a similar config file. For the rest of the documentation, you can generally assuming that references to yum-cron also apply to dnf-automatic.

On Scientific Linux the default behavior is also to disable yum-autoupdate.

class { 'yum_cron': }

These are the actions taken by the module with default parameter values:

• Install yum-cron/dnf-automatic
• Set configuration values to enable checking for updates and notify root
• Start and enable the yum-cron/dnf-automatic service
• Disable yum-autoupdate by setting ENABLED="false" in /etc/sysconfig/yum-autoupdate (Scientific Linux only)

This is an example of enabling automatic updates

class { 'yum_cron':
  apply_updates => true,
}

Refer to the yum-cron manpage for all available configuration options.

Additional configuration values can be passed to the yum-cron configurations via the extra_configs parameter.

To define additional configuration options for EL6:

class { 'yum_cron':
  extra_configs => {
    'yum_cron ERROR_LEVEL' => { 'variable' => 'ERROR_LEVEL', 'value' => '1' }
  }
}

To define additional configuration options for EL7:

class { 'yum_cron':
  extra_configs => {
    'email/email_from' => { 'value' => 'foo@bar.com' }
  }
}
