I'm still pretty new to ansible, so I feel like I am probably doing
something really stupid, but I cannot get the assert module to work.
I have ansible version 1.5.3. I'm getting "ERROR: assert is not a legal
parameter in an Ansible task or handler" in all my attempts to use an
assert. I've been searching the docs and all I can find is the doc which
gives a snippet example of using assert and my attempts to copy that aren't
working, and I can't find an actual complete playbook example that includes
the use of assert to compare to.
What I'm trying to do, assert may not even be the right approach for.
Basically I'm developing a playbook for automated reboots that is *very*
dangerous during production hours and which should only ever be allowed to
run on a Saturday during a designated window, and so I want the playbook to
include some explicit rules that will prevent it from rebooting when it's
not supposed to, even if some chucklehead accidentally executes it during
the week.
Ideally, I'd be able just reference an ansible fact for the day of the
week, but I can't seem to find one? So I'm using the date command to get
the day of the week and registering that into a variable. Then I want to
abort the playbook when that and another condition are not met.
My test playbook looks like this (the tasks that set commonWeekday and
commonResultBackup are in roles/common/tasks/main.yml):
REBOOTGROUP_SAT_10AM.yml:
---
- hosts: REBOOTGROUP_SAT_10AM
roles:
- common
tasks:
- assert:
that:
- commonWeekday.stdout == "Saturday"
- ansible_date_time.hour == "10"
- commonResultBackup!success
- name: Reboot the server with warning delay - Don't wait for it to
complete
command: shutdown -r +5 Automated Weekly Reboot
sudo: yes
async: 600
poll: 0
ignore_errors: true
And if I test it:
$ ansible-playbook --syntax-check REBOOTGROUP_SAT_10AM.yml
playbook: REBOOTGROUP_SAT_10AM.yml
ERROR: assert is not a legal parameter in an Ansible task or handler
