I do this using git and SaltStack. Here is my Salt state for managing the
root crontab.
cron:
service.running:
- name: cron
- enable: True
root-crontab:
file.managed:
- name: /root/root-crontab
- source: salt://cronjobs/root-crontab
- template: jinja
cmd.run:
- name: cd /root; /usr/bin/crontab -r; /usr/bin/crontab root-crontab
The file called root-crontab is under revision control. One of the things
that is in root-crontab is first, updating the Salt states and second,
invoking them. That could include updating the root-crontab. There are
other ways of doing this in SaltStack.
