Overview

Manage yum.conf and schedule automatic yum updates.

Usage

Default behaviour is for the module to hash the node's IP address to generate an hour and a minute for the update cron job to run, to stagger yum updates across your esate between 02:00 and 07:59 on weekdays.

hour

Cron hour that the update job should run, from 0-23. Default: $::cron_hour (a random value between 2-7)

minute

Cron minute that the update job should run, from 0-59. Default: $::cron_minute (a random value between 0-59)

weekday

Day(s) of the week that the update job should run, specified as an array. Default: ['1-5'] (weekdays only)

exclude

Array of packages to exclude from the update job

include ::yumupdate

If you want to force the same time on every node, set these parameters:

class { 'yumupdate':
  hour   => 5,
  minute => 30,
}

Example where we don't upgrade the kernel:

class { 'yumupdate':
  exclude => ['kernel'],
}

Limitations

Only works on systems that use Yum for package management. Designed with CentOS but should work on any RHEL-compatible Linux distribution.
