Overview

This module installs, configures, and manages ksplice for rebootless kernel upgrades.

Module Description

The ksplice module installs, configures, and manages ksplice to update your kernel without needing to reboot.

A license/access key from ksplice is required for rebootless upgrades to work.

The module will install the ksplice repository, install the uptrack package, and manage the ksplice configuration file.

This module follows semantic versioning.

Usage

Beginning with ksplice

If you have a license key and want to check for kernel updates every 30 minutes and automatically install them. This is what the normal manual installation of ksplice will do.

class { '::ksplice':
  config_accesskey => 'YOUR_LICENSE_KEY',
}

Custom cron times

By default uptrack runs every 30 minutes unless you give it a custom cron time.

class { '::ksplice':
  config_accesskey  => 'YOUR_LICENSE_KEY',
  config_proxy      => 'https://your.proxy.server:port',
  cron_minute       => '13',
  cron_hour         => '03',
  cron_month        => '*',
  cron_monthday     => '*',
  cron_weekday      => '*',
}

Facts

uptrack-uname will print out the effective version of kernel after patching. It accepts uname(1) command-line options and produces compatible output. There are facts, using uptrack-uname, corresponding to the kernel facts that already come with facter.

  • ksplice_kernelrelease: effective kernel release
  • ksplice_kernelversion: effective kernel version
  • ksplice_kernelmajversion: effective kernel major version
  • ksplice_kernel_package_version: effective version of the distribution's kernel package

Development

Install necessary gems:

bundle install --path vendor/bundle

Check syntax of all puppet manifests, erb templates, and ruby files:

bundle exec rake validate

Run puppetlint on all puppet files:

bundle exec rake lint

Run spec tests in a clean fixtures directory

bundle exec rake spec

Run acceptance tests with a ksplice license:

KSPLICE_LICENSE=abc123 PUPPET_INSTALL_TYPE=agent BEAKER_set=centos-7-x64 bundle exec rake acceptance

Run acceptance tests on docker without a ksplice license (faster):

PUPPET_INSTALL_TYPE=agent BEAKER_set=docker/centos-7-x64 bundle exec rake acceptance
