puppet-module-cron

Manage the cron configuration files.

• /etc/crontab
• /etc/cron.allow
• /etc/cron.deny
• /etc/cron.d/
• /etc/cron.hourly
• /etc/cron.daily
• /etc/cron.weekly
• /etc/cron.monthly
• /etc/cron.yearly

Compatibility

This module has been tested to work on the following systems with Puppet v3 (with and without the future parser) and Puppet v4 with Ruby versions 1.8.7, 1.9.3, 2.0.0, 2.1.0 and 2.3.1.

• EL 5
• EL 6
• SLES 10
• SLES 11
• SLES 12
• Ubuntu 12

Note that SLES patches ISC's cron such that if cron.allow and cron.deny are both missing, then root will not be able to access the crontabs. This will cause errors. Please see the Hiera example below.

Sample usage:

Work on Suse

cron::cron_allow: 'present'

  - root

Define crontab variables

cron::crontab_vars:
  SHELL: /bin/bash
  PATH: /sbin:/bin:/usr/sbin:/usr/bin
  MAILTO: root
  HOME: /root

Create /etc/cron.daily/daily_task

cron::cron_files:
     'daily_task':
       ensure: 'present'
       type: 'daily'
       content: |
            #!/bin/bash
            # This File is managed by puppet
            command

Manage /etc/cron.allow

cron::cron_allow_users:
     - user1

Manage /etc/cron.deny

cron::cron_deny: 'present'
cron::cron_deny_users:
     - user1

Manage /etc/crontab

cron::crontab_tasks:
   'task1':
    - "* 12 * * 7 username echo 'Hello World'"

   'task2':

By default this is called from the parent class cron. Data is provided for description.

Group owner of the user's crontab file. Default is undef which will result in the filename and group being the same.

• Default: undef

Usage

Simply insert the hiera data in your hiera hierarchy and there will be a hiera_hash of all hiera levels.

Hiera data structure to be used by the parent class cron:

cron::user_crontabs:
  'user1':
    vars:
      'SHELL': '/bin/bash'
      'MYECHO': '$(which echo)'
    entries:
      '# Echo Hello World':
        - '* 1 * * * $MYECHO "Hello World!" 2>&1'
  'user2':
    vars:
      'SHELL': '/bin/bash'
      'MYECHO': '$(which echo)'
    entries:
      '# Echo Hello World':
        - '* 3 * * * $MYECHO "Hello user2!" 2>&1'

Example of how to create resources function outside of the cron module.

  $user_crontabs => {
    'user1' => {'vars' => [ 'SHELL': '/bin/bash', 'MYECHO': '$(which echo)' ], 'entries' => [ '# Echo Hello World': '* 1 * * * $MYECHO "Hello World!"' ]},
    'user2' => {'vars' => [ 'SHELL': '/bin/bash', 'MYECHO': '$(which echo)' ], 'entries' => [ '# Echo Hello World': '* 3 * * * $MYECHO "Hello user2!"' ]}
  }
  create_resources(cron::user::crontab, $user_crontabs)
