cronner

The cronner cookbook installs cronner
and provides an LWRP for configuring cron jobs that are wrapped with cronner.
The LWRP is a wrapper of the cron_d LWRP and injects the cronner invocation
before your command allowing the status and metrics to be collected.

License

This cookbook is licensed under the Apache 2.0 License. Please refer to
the LICENSE
file for the full contents of the license.

Recipe Usage

This cookbook intends to try and track all major versions of the cronner
binary, to make it easy to switch between versions just with an attribute
change. By default this cookbook uses the latest version if one is not specified
otherwise. To install cronner, just execute the cronner::default recipe by
including it one of your recipes or by adding it to the run_list.

Recipe Attributes

This cookbook only has one attribute to impact the installation
(node['cronner']['default_install_version']), which takes the cronner version
string (e.g., 0.4.2) that you want to have installed.

LWRP Usage

The cronner cookbook provides an LWRP to install cron jobs that are monitored
by cronner. This LWRP is a light wrapper around the stellar cron_d LWRP from
the cron cookbook. That means the
cronner LWRP has all the same attributes available as the cron_d LWRP. For
information on the cron_d resource please view the Resource and Providers
section of the cron cookbook's
README.

  # cronner is meant to replace the usage of mailto to alert you of errors or problems
  # however, it's a good idea to still set it if cronner were to hit its own internal issues
  # this actually happened in an early version of cronner where it would randomly hit a stdlib bug
