I made a simple playbook to show the issue. It seems ansible evalutes all
variables regardless of the conditional result before ternary.
If you run the playbook twice, once with "simpleDict" defined, and again
with it commented out.
---
#TESTING: ternary behaviour
- name: Run - Testing ternary
sudo: yes
hosts: "{{hosts}}"
gather_facts: no
vars:
simpleDict:
# name: 'A simple dictionary'
# nestedDict: {}
tasks:
- set_fact: foo="{{ simpleDict is defined |
ternary(simpleDict.nestedDict|default({}),"simpleDict not defined") }}"
- debug: var=foo
Thanks
