Description

This module is an interface for cron jobs with the main idea to be tidy. That means that any jobs that are not managed should not exist. Once you switch all cron jobs to this module, simply removing the definition is sufficient without worrying about setting ensure => disable and waiting for changes to propagate.

Setup

Beginning with cron

To start out with cron:

include cron

This will start purging all unmanaged cron resources and also make sure the 'cron' package is installed and the service is running.

WARNING: All existing unmanaged cron jobs will be purged!

Usage

Also manage /etc/cron.d directory

class { 'cron':
  purge_crond => true,
}

Same result through Hiera:

cron::purge_crond: true

Wipe it all out

class { 'cron':
  ensure => absent,
}

Same result through Hiera:

cron::ensure: absent

cron::job example

cron::job { 'backup':
  user     => 'backup', # default: 'root'
  minute   => '3-59/5',
  hour     => '9-17',
  monthday => '*/2',
  month    => [ 4, 8, 12 ],
  weekday  => '0-4',
}

cron::whitelist example

cron::whitelist { 'pkg_backup': }

This will make /etc/cron.d/pkg_backup immune, and keep the file's contents untouched.

Reference

Type Aliases

  • Cron::Command - Used for cron::job::command parameter. Does not allow newline characters (which breaks crontab).
  • Cron::User - Match username to fail early if invalid username is provided.
  • Cron::Minute - Stricter cron::job::minute.
  • Cron::Hour - Stricter cron::job::hour.
  • Cron::Monthday - Stricter cron::job::monthday.
  • Cron::Month - Stricter cron::job::month.
  • Cron::Weekday - Stricter cron::job::weekday.

Limitations

  • Made for and tested only on the following Ubuntu distributions:
    • 14.04
    • 16.04
    • 18.04
  • Custom Cron::* time types are a lot stricter than builtin cron ones. Careful - this may break existing cron jobs you are converting.
  • All cron jobs managed by built-in cron type are fair play. They won't be purged as long as they're in the catalog. But using this module's cron::job type does have its advantages.

Development

I'll be happy to know you're using this for one reason or the other. And if you want to contribute - even better. Feel free to submit an issue / fire up a PR / whatever.
