z3c.recipe.usercrontab

Z3c.recipe.usercrontab is a project mainly written in Python, based on the View license.

User Crontab install buildout recipe

====================== z3c.recipe.usercrontab

The problem

When deploying applications, it can be useful to have maintenance tasks be started periodically. On Unix platforms this is usually done using cron which starts cronjobs. Adding cronjobs to the system-wide cron directory (for example by placing a file in /etc/cron.d) can be handled using the zc.recipe.deployment package, but it does not support adding cronjobs by normal users. (as /etc/cron.d usually is world-writable).

The solution

z3c.recipe.usercrontab interfaces with cron using crontab(1), and allows normal users to install their own cronjobs. This is done by having buildout add and remove cronjobs when installing and uninstalling packages.

How to use it

To use z3c.recipe.usercrontab you need to add the following to your buildout.cfg::

[mycronjob] recipe = z3c.recipe.usercrontab times = 0 12 * command = echo nothing happens at noon

and finally add mycronjob to the parts line(s) of your buildout.cfg
