Actually, example without lookup at all:
- name: Test random
set_fact:
rand_result: "{{ 5 | random }}"
until: rand_result == 'NEVER'
retries: 10
delay: 1
If I run ansible in verbose mode I see that on all iterations rand_result
var have the same value, so jinja template evaluated once.
How can I force reevaluate it on every iteration?
