Module description

This is yet another puppet-cron module. It will set up cron (by installed the package and making sure the service is running) and also includes a defined type which will put cron jobs in /etc/cron.d

The cron::job type can:

  • Set up locking, using flock, meaning cronjobs don't clobber each other
  • If you use sensu, alert when they fail, using sensu-wrapper

This module has some similarities to Yelp's puppet-cron with the intention of being much simpler while still providing some of the cool stuff in that module

Setup

What puppet-cron affects

  • puppet-cron will ensure the cronie or cron package is installed
  • It will may modify the permissions of several cron directories, like /etc/crond.d

Beginning with puppet-cron

Simply include the cron module like so:

  include ::cron

You may want to use a class include if you wish to override parameters:

  class { '::cron' :
        crond_dir => '/etc/cron'
  }

Usage

I just want to manage cron, what's the minimum I need

  include ::cron

I want to create a cron job

Use the cron::job defined type:

  ::cron::job {
    minute => '02',
    hour   => '1',
    lock   => true
  }

This will create a cronjob file in $crond_dir (default: /etc/cron.d) which will run on the schedule you specified.
