Puppet module for configuring systems for automatic package updates. This module provides a custom update mechanism which utilizes distribution package managers, allowing for a consistent update experience across supported distributions.
This module is designed to run from a cron task, and will only output on a failed return code from a task.
The following distributions are known to be supported:
- CentOS/RHEL 5-7
- Ubuntu 14.04
Please file an issue if you have successfully tested this on other apt/yum systems.
Default update mechanism is once a week on Wed at 4am with a random minute (0-59). These can be customized with class paramaters.
class { '::systemupdates':
day => 'Wed',
hour => '4',
minute => fqdn_rand(59),
auto_reboot => false,
}
You can use Hiera to customize the configuration more granularly. Make sure to use single quotes if referencing the shell script variables
systemupdates::use_crontab: false
systemupdates::use_anacron: 'daily'
systemupdates::pkgtosvcrestart:
jre:
- elasticsearch
- logstash
elasticsearch: "elasticsearch"
systemupdates::custom_commands:
- 'apt-get -y $APTARGS dist-upgrade puppet'
- 'apt-get -y $APTARGS -f install'
- 'apt-get -y $APTARGS autoremove'
systemupdates::pkgtosystemreboot:
- glibc
- openssl
