Hi,
I am introducing group_vars & children in my inventory into my Ansible
environment as I need to update cron-tabs for different geographical
regions using templates the basics of what you can see below. When I run
the playbook it produces the error as seen at the bottom. A bit of research
tells me that I am not the only 1 to see similar errors. Is this a bug that
can be fixed with an upgrade or are there work-arounds? I've tried the vars
file with different formatting to no avail.
Version Info : ansible 2.2.1.0
e.g. Template
{{ daily_min }} {{ daily_hr }} * * 0 /path/weekly.sh > /dev/null 2>&1
{{ weekly_min }} {{ weekly_hr }} * * * /path/chk.sh > /dev/null 2>&1
e.g. Group_var
---
- crons:
- { daily-min: "15", daily-hr: "01" }
- { weekly-min: "15", weekly-hr: "03" }
e.g. Playbook
- name: create crontab
tags: cron
template:
src: templates/cron.template
dest: /var/spool/cron/user
owner: root
group: root
mode: 0644
backup: yes
# ansible-playbook --ask-become-pass push-crons.yml --limit hostname
--check -vvv
